# In-App Experiences Implement Scenes, In-App Automations, custom views, and embedded content to deliver engaging in-app experiences to your users. # In-App Experiences > Integrate Scenes & In-App Automations into your Apple app to display embedded content and create custom in-app experiences with minimal code. In-App Experiences use Airship's on-device automation framework to provide instant, personalized content that integrates natively with your app. This includes [Scenes](https://www.airship.com/docs/reference/glossary/#scene), which can be displayed as modal or fullscreen overlays or embedded directly within your app screens, and In-App Automations (IAA), which power banner, modal, and fullscreen in-app messages triggered by events. Scenes are fully customizable in the Airship dashboard and require minimal SDK integration. For advanced In-App Automation customization options, see [In-App Automation](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/in-app-automation/). ## Requirements To use In-App Experiences, you need: - The `AirshipAutomation` module installed (see [Getting Started](https://www.airship.com/docs/developer/sdk-integration/apple/installation/getting-started/)) - Airship SDK initialized with `takeOff` (see [Getting Started](https://www.airship.com/docs/developer/sdk-integration/apple/installation/getting-started/)) > **Note:** **In-App Experiences work out of the box**: Once you install the `AirshipAutomation` module and initialize Airship with `takeOff`, In-App Experiences will function automatically. The rest of this documentation covers optional customization and advanced features. ## Adding custom fonts Custom fonts added to your app bundle can be used in In-App Experiences. To add fonts to your app, follow Apple's guide on [Adding a Custom Font to Your App](https://developer.apple.com/documentation/uikit/text_display_and_fonts/adding_a_custom_font_to_your_app). Once added, you'll need the font family name to use it in Airship. To find the family name: 1. Add the font files to your Xcode project 2. Use this code to print all available font family names: #### Swift ```swift for family in UIFont.familyNames.sorted() { print("Family: \(family)") for name in UIFont.fontNames(forFamilyName: family) { print(" - \(name)") } } ``` #### Objective-C ```objc for (NSString *familyName in [UIFont familyNames]) { NSLog(@"Family: %@", familyName); for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) { NSLog(@" - %@", fontName); } } ``` After adding fonts to your app, create a Font Stack in the Airship dashboard by following the steps in [Setting brand guidelines](https://www.airship.com/docs/guides/messaging/features/brand-guidelines/). You can then select the stack when [setting In-App Experience defaults](https://www.airship.com/docs/guides/messaging/in-app-experiences/configuration/defaults/) and creating in-app messages. ## Controlling display Control when and how In-App Experiences are displayed in your app. You can auto-pause displays on launch (useful for splash screens), manually pause all in-app displays, set intervals between displays, control when individual messages are ready to display, and specify which scene window displays messages in multi-scene apps. ### Auto-pausing on launch For apps with splash screens, you can configure Airship to automatically pause In-App Automation on launch. This prevents In-App Experiences from displaying during the splash screen. Once your app is ready, resume display by setting `isPaused` to `false`. Set the `autoPauseInAppAutomationOnLaunch` option in your Airship config when calling `takeOff`: #### Swift ```swift var config = AirshipConfig() // ... other config settings ... // Auto-pause on launch for splash screen config.autoPauseInAppAutomationOnLaunch = true try! Airship.takeOff(config) // Later, when splash screen is dismissed and app is ready: Airship.inAppAutomation.isPaused = false ``` #### Objective-C ```obj-c UAConfig *config = [UAConfig config]; // ... other config settings ... // Auto-pause on launch for splash screen config.autoPauseInAppAutomationOnLaunch = YES; [UAirship takeOff:config error:&airshipError]; // Later, when splash screen is dismissed and app is ready: UAirship.inAppAutomation.isPaused = NO; ``` ### Pausing display Pausing will still allow In-App Experiences to be triggered and queued up for execution, but they will not display. This is useful for preventing in-app experiences from displaying on screens where it would be detrimental to the user experience, such as splash screens, settings screens, or landing pages. #### Swift ```swift Airship.inAppAutomation.isPaused = true ``` #### Objective-C ```obj-c Airship.inAppAutomation.isPaused = YES ``` ### Display interval The display interval controls the amount of time to wait before the manager can display the next triggered In-App Experience. The default value is set to **0 seconds** and can be adjusted to any amount of time in seconds. #### Swift ```swift Airship.inAppAutomation.inAppMessaging.displayInterval = 30 ``` #### Objective-C ```obj-c UAirship.inAppAutomation.inAppMessaging.displayInterval = 30 ``` ### Controlling per-message display You can control when individual In-App Experiences are ready to display and listen for when they are displayed or finished. This is useful when you need to check app state before displaying content, such as: - Verifying the current screen or view controller is appropriate for the message - Checking custom data in the message's extras (custom keys) to determine if it should display - Ensuring certain app conditions are met before showing the message - Integrating with other in-app messaging products #### Swift Set a closure on to control the display. You have access to the message and schedule ID: ```swift Airship.inAppAutomation.inAppMessaging.onIsReadyToDisplay = { message, scheduleID in // Return false to prevent display return false } ``` `onIsReadyToDisplay` will be called whenever state in the app changes (screen, app state, message finished displaying, etc...), you can also trigger it manually with `notifyDisplayConditionsChanged`: ```swift Airship.inAppAutomation.inAppMessaging.notifyDisplayConditionsChanged() ``` #### Objective-C Implement the `InAppMessageDisplayDelegate` to control the display. You have access to the message and schedule ID: **Implement the InAppMessageDisplayDelegate** ```obj-c - (BOOL)isMessageReadyToDisplay:(UAInAppMessage *)message scheduleID:(NSString *)scheduleID { // Return NO to prevent display return NO; } ``` **Set the delegate** ```obj-c UAirship.inAppAutomation.inAppMessaging.displayDelegate = self; ``` `isMessageReadyToDisplay` will be called whenever state in the app changes (screen, app state, message finished displaying, etc...), you can also trigger it manually with `notifyDisplayConditionsChanged`: ```obj-c [UAirship.inAppAutomation.inAppMessaging notifyDisplayConditionsChanged]; ``` ### Displaying in multiple scene apps By default, In-App Experiences are displayed in the last active window scene. The [InAppMessageSceneDelegate](https://urbanairship.github.io/ios-library/v20/AirshipAutomation/documentation/airshipautomation/inappmessagescenedelegate) allows you to override this behavior and control which UIWindowScene displays a given in-app message. Use this delegate when your app supports multiple scenes and you need to customize which scene displays the message. #### Swift **Implement the InAppMessageSceneDelegate** ```swift func sceneForMessage(_ message: InAppMessage) -> UIWindowScene? { // return a custom scene or nil to use default } ``` **Set the delegate** ```swift Airship.inAppAutomation.inAppMessaging.sceneDelegate = sceneDelegate ``` #### Objective-C **Implement the InAppMessageSceneDelegate** ```obj-c - (UIWindowScene *)sceneForMessage:(UAInAppMessage *)message { // return a custom scene or nil to use default return nil; } ``` **Set the delegate** ```obj-c UAirship.inAppAutomation.inAppMessaging.sceneDelegate = self; ``` ## Next steps - Learn how to [create Scenes in the Airship dashboard](https://www.airship.com/docs/guides/messaging/in-app-experiences/scenes/create/) - Present Scene content with [Embedded Content](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/embedded-content/) - Create reusable components with [Custom Views](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/custom-views/) - Customize [In-App Automation](https://www.airship.com/docs/developer/sdk-integration/apple/in-app-experiences/in-app-automation/) for IAA # Embedded Content > Integrate Embedded Content into your iOS app to display Scene content directly within your app's screens. For information about Embedded Content, including overview, use cases, and how to create Embedded Content view styles and Scenes, see [Embedded Content](https://www.airship.com/docs/guides/features/messaging/scenes/embedded-content/). ## Adding an embedded view The `AirshipEmbeddedView` is a SwiftUI view that defines a place for an Airship Embedded Content to be displayed. When defining an `AirshipEmbeddedView`, specify the `embeddedId` for the content it should display. The value of the `embeddedId` must be the ID of an Embedded Content view style in your project. **Basic integration** ```swift // Show any "home_banner" Embedded Content AirshipEmbeddedView(embeddedID: "home_banner") ``` ## Placeholders If content is unavailable to display, the default behavior is to show an `EmptyView`. You can customize this by providing a placeholder. **Basic integration with placeholder** ```swift AirshipEmbeddedView(embeddedID: "home_banner") { Text("Placeholder!") } ``` ## Placing in a scroll view When placed directly in a `ScrollView`, or a child view within the `ScrollView` that is allowed to grow unbounded in the scrollable direction, you need to pass the maximum size of the embedded view to make percent-based sizing work correctly. The easiest way is to wrap the `ScrollView` in a `GeometryReader` and pass the size info to the embedded view. **GeometryReader example** ```swift struct ScrollViewExample: View { var body: some View { GeometryReader { geometryProxy in ScrollView(showsIndicators: false) { AirshipEmbeddedView( embeddedID: "home_banner", embeddedSize: AirshipEmbeddedSize( parentBounds: geometryProxy.size ) ) } } } } ``` When using a `GeometryReader`, it takes up as much space as allowed. To avoid this and instead measure the current size of the content, you can use the view extension `airshipMeasureView`. **airshipMeasureView example** ```swift struct ScrollViewExample: View { @State var state: CGSize? var body: some View { ScrollView(showsIndicators: false) { AirshipEmbeddedView( embeddedID: "home_banner", embeddedSize: AirshipEmbeddedSize( maxWidth: state?.width, maxHeight: state?.height ) ) } .airshipMeasureView(self.$state) } } ``` ## Styling You can set a custom style on the embedded view, which allows you to modify how the content is displayed or what pending content is displayed. In this example, the embedded view has a Dismiss Button above it: **Custom style** ```swift public struct CustomEmbeddedViewStyle: AirshipEmbeddedViewStyle { @ViewBuilder public func makeBody(configuration: AirshipEmbeddedViewStyleConfiguration) -> some View { if let view = configuration.views.first { VStack { Button("Dismiss") { view.dismiss() } view } } else { configuration.placeHolder } } } ``` **Setting the style** ```swift AirshipEmbeddedView(embeddedID: "home_banner") .setAirshipEmbeddedStyle(CustomEmbeddedViewStyle()) ``` ## Observing available embedded content Embedded Content is not always available, and even after being triggered, it still needs to be prepared before it can be displayed. An `AirshipEmbeddedView` will automatically update when content is available and transition from the placeholder to the content once content is available. If you need to query the availability of Embedded Content, you can use an `AirshipEmbeddedObserver` to watch for updates. An `AirshipEmbeddedObserver` is an `ObservableObject` that you can use as a `StateObject` to automatically refresh the view when new Embedded Content is available. It allows for more dynamic handling of Embedded Content than just content or a placeholder. **Observable example** ```swift struct ObservableExample: View { @StateObject private var embeddedObserver: AirshipEmbeddedObserver = AirshipEmbeddedObserver(embeddedID: "home_banner") @State var tabIndex = 0 var body: some View { if (embeddedObserver.embeddedInfos.isEmpty) { Text("No banner available") } else { Text("Banner available") AirshipEmbeddedView(embeddedID: "home_banner") } } } ``` The `AirshipEmbeddedObserver` can be created to watch for one `embeddedID`, all embedded IDs, or use custom filtering for embedded IDs. The `embeddedInfos` is the FIFO order of embedded info, including the extras you can set through the Scene composer when creating the content. # Custom Views > Register custom SwiftUI views with the AirshipCustomViewManager to use them in Scenes. ![Custom View rendered in a Scene on iOS](https://www.airship.com/docs/images/custom-views-apple_hu_32d8fbb68fdc44c2.webp) *Custom View rendered in a Scene on iOS* To use Custom Views, you must first register the view's name with the `AirshipCustomViewManager`. The name is referenced when adding the Custom View to a Scene. The view manager will call through to the view builders registered for that view's name and provide the properties, name, and some layout hints as arguments. All Custom Views should be registered [after takeOff](https://www.airship.com/docs/developer/sdk-integration/apple/installation/getting-started/). #### Swift ```swift struct CustomViewProperties: Decodable { var text: String } AirshipCustomViewManager.shared.register(name: "custom_view") { args in let viewProperties: CustomViewProperties = if let decoded = try? args.properties?.decode() { decoded } else { CustomViewProperties(text: "fallback") } Text(viewProperties.text) } ``` ## Example custom view The following example shows a Custom View that renders an embedded map when called to render a Custom View named `map`. In our example, we have `properties` that defines a single `place` field, which is the address of the location that the map should render. #### Swift First, define the view and its properties: ```swift import SwiftUI import MapKit import CoreLocation struct CustomMapView: View { struct Args: Decodable { let place: String } let args: Args @State private var region: MKCoordinateRegion? @State private var pinCoordinate: CLLocationCoordinate2D? var body: some View { if let region = region, let pinCoordinate = pinCoordinate { Map(coordinateRegion: .constant(region), annotationItems: [MapPin(coordinate: pinCoordinate)]) { pin in MapMarker(coordinate: pin.coordinate, tint: Color.red) } } else { Text("Loading map...") .onAppear { geocodePlace() } } } private func geocodePlace() { let geocoder = CLGeocoder() geocoder.geocodeAddressString(args.place) { placemarks, error in if let placemark = placemarks?.first, let location = placemark.location { let coordinate = location.coordinate self.region = MKCoordinateRegion( center: coordinate, span: MKCoordinateSpan(latitudeDelta: 0.05, longitudeDelta: 0.05) ) self.pinCoordinate = coordinate } else { print("Failed to geocode place: \(error?.localizedDescription ?? "Unknown error")") } } } } struct MapPin: Identifiable { let id = UUID() let coordinate: CLLocationCoordinate2D } struct CustomMapView_Previews: PreviewProvider { static var previews: some View { CustomMapView(args: CustomMapView.Args(place: "Eiffel Tower")) } } ``` Then register the view after takeOff: ```swift AirshipCustomViewManager.shared.register(name: "map", builder: { args in if let args: CustomMapView.Args = try? args.properties?.decode() { CustomMapView(args: args) } }) ``` ## Scene Control Custom views control their parent scene through the `AirshipSceneController`, which is automatically injected as an `@EnvironmentObject`. ### Accessing SceneController Declare the scene controller as an `@EnvironmentObject` property in your custom view. #### Swift ```swift struct CustomMapView: View { @EnvironmentObject var sceneController: AirshipSceneController let args: Args var body: some View { // Your custom view content } } ``` ### Dismissing scenes Call `dismiss()` to close the scene, or set `cancelFutureDisplays` to prevent it from displaying again. #### Swift ```swift struct CustomMapView: View { @EnvironmentObject var sceneController: AirshipSceneController var body: some View { VStack { // Map display code... Button("Close Map") { sceneController.dismiss() } Button("Got It") { sceneController.dismiss(cancelFutureDisplays: true) } } } } ``` ### Pager navigation Navigate between pages using the `pager` controller's `canGoBack` and `canGoNext` properties. #### Swift ```swift struct CustomMapView: View { @EnvironmentObject var sceneController: AirshipSceneController var body: some View { HStack { if sceneController.pager.canGoBack { Button("Back") { sceneController.pager.navigate(request: .back) } } if sceneController.pager.canGoNext { Button("Next Location") { sceneController.pager.navigate(request: .next) } } } } } ``` ### Sizing management Use `args.sizeInfo` to determine appropriate sizing for your custom view. #### Swift ```swift AirshipCustomViewManager.shared.register(name: "map") { args in if let args: CustomMapView.Args = try? args.properties?.decode() { CustomMapView(args: args) .frame( width: args.sizeInfo.isAutoWidth ? 350 : nil, height: args.sizeInfo.isAutoHeight ? 500 : nil ) } } ``` ![Map Custom View in a Scene on iOS](https://www.airship.com/docs/images/custom-views-map-scene-apple_hu_46a1471648ebe081.webp) *Map Custom View in a Scene on iOS* ## Embedding Airship Views Airship views like Preference Center can be embedded as custom views. #### Swift ```swift // Full preference center with navigation bar AirshipCustomViewManager.shared.register(name: "preference_center") { args in let id = args.properties?.object?["id"]?.string ?? "default" return PreferenceCenterView(preferenceCenterID: id) .frame( maxWidth: args.sizeInfo.isAutoWidth ? nil : .infinity, maxHeight: args.sizeInfo.isAutoHeight ? nil : .infinity ) } // Content only (no navigation bar) AirshipCustomViewManager.shared.register(name: "preference_center_content") { args in let id = args.properties?.object?["id"]?.string ?? "default" return PreferenceCenterContent(preferenceCenterID: id) .frame( maxWidth: args.sizeInfo.isAutoWidth ? nil : .infinity, maxHeight: args.sizeInfo.isAutoHeight ? nil : .infinity ) } ``` ![Preference Center Custom View in a Scene on iOS](https://www.airship.com/docs/images/custom-views-preference-center-scene-apple_hu_6e4d0728f598b316.webp) *Preference Center Custom View in a Scene on iOS* # In-App Automation > Integrate options for In-App Automation (IAA) customization. In-App Automation (IAA) powers banner, modal, and fullscreen in-app messages. ## Customization Various options are available for customizing the container view for In-App Automation content via the native SDKs. Scenes are fully customizable in the dashboard and cannot be customized via the SDK. ## Styles Plists can be used to modify any of the default message styles that the SDK provides. Each message type can be customized with a different plist: - **Banner**: `UAInAppMessageBannerStyle.plist` - **HTML**: `UAInAppMessageHTMLStyle.plist` - **FullScreen**: `UAInAppMessageFullScreenStyle.plist` - **Modal**: `UAInAppMessageModalStyle.plist` These plists support the following values: - **Banner** - `additionalPadding`: _Padding_.

To add fonts, please read the [The UIKit Custom Fonts Guide](https://developer.apple.com/documentation/uikit/text_display_and_fonts/adding_a_custom_font_to_your_app). ![iOS Custom Font](https://www.airship.com/docs/images/ios/ios-custom-font_hu_abb515eea5dfec6b.webp) *iOS Custom Font* After adding fonts to your app, create a Font Stack in the Airship dashboard by following the steps in [Setting brand guidelines](https://www.airship.com/docs/guides/messaging/features/brand-guidelines/). Then you can select the stack when [setting in-app message defaults](https://www.airship.com/docs/guides/messaging/in-app-experiences/configuration/defaults/) and creating in-app messages. ### Dynamic fonts With HTML in-app messages Most In-App message styles support automatically scaling fonts through the use of Dynamic Type. However, automatically scaling fonts in HTML In-App messages requires you to use the following Apple system fonts when specifying the CSS font property: - `-apple-system-body` - `-apple-system-headline` - `-apple-system-subheadline` - `-apple-system-caption1` - `-apple-system-caption2` - `-apple-system-footnote` - `-apple-system-short-body` - `-apple-system-short-headline` - `-apple-system-short-subheadline` - `-apple-system-short-caption1` - `-apple-system-short-footnote` - `-apple-system-tall-body` For example, to have the HTML body default to the Apple system font body style: ```html body { font: -apple-system-body; // available on Apple devices only } ``` For more information about dynamic type, please see this [WWDC video](https://developer.apple.com/videos/play/wwdc2017/245/). ## Customizing HTML In-App Messages > **Note:** In order for the Airship JavaScript interface to be loaded into the webview, the URL must be specified in the URL Allowlist. See [Advanced Integration](https://www.airship.com/docs/developer/sdk-integration/apple/installation/advanced-integration/#url-allowlist) for configuration details. HTML in-app messages provide a way to display custom content inside a native web view. These types of in-app messages display with a dismiss button built in, but can also be customized to provide their own buttons capable of dismissing the view. Dismissing a view requires calling the dismiss function on the UAirship JavaScript interface with a button resolution object passed in as a parameter. The button resolution object is a JSON object containing information about the interaction type and the button performing the dismissal. It should match the following format: ```javascript { "type" : "button_click", "button_info" : { "id" : "button identifier", "label" : {"text": "foo"} } } ``` The button resolution requires each of the key fields shown above. These include: - `type` — The type key with the value of resolution type `button_click` - `button_info` — The button info object containing required id and label fields - `id` — The button identifier - `label` — Label object containing the required text key - `text` — The text key with a string value representing the label text Providing a basic dismiss button in HTML: ```html ``` ## Custom adapters Providing an adapter allows defining the behavior of the custom type or overriding any of the default message types. The adapter will be created by the in-app messaging manager when a message's schedule is triggered. Once created, the adapter can define when the message is ready to display and the display behavior. After the message is displayed, the caller of the display method must be notified that the message is finished displaying by returning a `CustomDisplayResolution` when finished. This will allow for subsequent in-app messages to be displayed. **Example custom banner adapter** ```swift final class CustomBannerAdapter: CustomDisplayAdapter { private let message: InAppMessage private let assets: AirshipCachedAssetsProtocol init(message: InAppMessage, assets: any AirshipCachedAssetsProtocol) { self.message = message self.assets = assets } @MainActor var isReady: Bool { get { /// Called before display return true } } @MainActor func waitForReady() async { // If `isReady` is false this will be called to wait for the // adapter to be ready } @MainActor func display(scene: UIWindowScene) async -> CustomDisplayResolution { return await withCheckedContinuation { continuation in /// After displaying call the continuation with the result continuation.resume(returning: .userDismissed) } } } ``` **Register a factory block to return the adapter** ```swift /// Set the factory block after takeOff InAppAutomation.shared.inAppMessaging.setAdapterFactoryBlock(forType: .banner) { message, assets in return CustomBannerAdapter(message: message, assets: assets) } ```
