Installation and initialization

Before using the AppMetrica Push SDK 2.2.1, you need to enable and initialize the AppMetrica SDK version 5.0.0 or higher.

Step 1. Enable the library

The library can work with the following dependency managers:

To connect the Push SDK library, add the following dependencies to your project's Podfile:

pod 'AppMetricaPush', '~> 2.2.1' # Main module for working with Push SDK, it's required for connecting
pod 'AppMetricaPushLazy', '~> 2.2.1' # Additional module for lazy push notifications

Integration via the Xcode interface

To connect the library, follow these steps:

  1. In the Xcode project navigator (Project Navigator) window, select your project (if Workspace is used). In the top menu, click File and select Add Package Dependencies....

  2. Specify the repository URL https://github.com/appmetrica/push-sdk-ios.

  3. Leave only the required modules (to disable a module, select None in Add to Target):

    • AppMetricaPush: The main mandatory Push SDK module. You need to enable it to use AppMetrica.
    • AppMetricaPushLazy: Additional module for lazy push notifications.

Integration via the Package.swift manifest

First, add the following dependency to the dependencies: array of your package:

dependencies: [
   .package(
      url: "https://github.com/appmetrica/push-sdk-ios",
      from: "2.2.1"
   )
],

The AppMetrica Push SDK modules that you can enable depending on the needs of your project:

  • AppMetricaPush: The main mandatory Push SDK module. You need to enable it to use AppMetrica.
  • AppMetricaPushLazy: Additional module for lazy push notifications.

Example of connecting modules in the dependencies: array of the target:

.target(
   name: "MyTargetName",
   dependencies: [
      .product(name: "AppMetricaPush", package: "push-sdk-ios"),
      // .product(name: "AppMetricaPushLazy", package: "push-sdk-ios"), // This module is disabled
   ]
),

Step 2. Register your app in the Apple Push Notification Service (APNs)

Registration prepares the app to work with push notifications. To send notifications to iOS devices, make the following changes to the app's code:

let center = UNUserNotificationCenter.current()
center.requestAuthorization(options:\[.badge, .alert, .sound\]) { (granted, error) in
  // Enable or disable features based on authorization.
}
application.registerForRemoteNotifications()

This data is usually passed in the following method:

func application(_ application: UIApplication, didFinishLaunchingWithOptions
                 launchOptions: [UIApplicationLaunchOptionsKey :Any]? = nil) -> Bool

For more details about the methods used, see the documentation at developer.apple.com:

UNAuthorizationOptions options =
  UNAuthorizationOptionAlert |
    UNAuthorizationOptionBadge |
    UNAuthorizationOptionSound;
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:options completionHandler:^(BOOL granted, NSError *error) {
  // Enable or disable features based on authorization.
}];
[application registerForRemoteNotifications];

This data is usually passed in the following method:

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

For more details about the methods used, see the documentation at developer.apple.com:

Step 3. Register a device token for your app

To send push notifications using AppMetrica, your app's device token is required. To register it:

Add the following code to AppDelegate:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    // If the AppMetrica SDK library was not initialized before this step,
    // calling the method causes the app to crash.
    AppMetricaPush.setDeviceTokenFrom(deviceToken)
}

Add the following code to your implementation of UIApplicationDelegate:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    // If the AppMetrica SDK library was not initialized before this step,
    // calling the method causes the app to crash.
    [AMPAppMetricaPush setDeviceTokenFromData:deviceToken];
}

To register the device token and send the APN environments, add the following code:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
{
    // If the AppMetrica SDK library was not initialized before this step,
    // calling the method causes the app to crash.
    #if DEBUG
        let pushEnvironment = AppMetricaPushEnvironment.development
    #else
        let pushEnvironment = AppMetricaPushEnvironment.production
    #endif
    AppMetricaPush.setDeviceTokenFrom(deviceToken, pushEnvironment: pushEnvironment)
}
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    // If the AppMetrica SDK library was not initialized before this step,
    // calling the method causes the app to crash.
    #ifdef DEBUG
        AMPAppMetricaPushEnvironment pushEnvironment = AMPAppMetricaPushEnvironmentDevelopment;
    #else
        AMPAppMetricaPushEnvironment pushEnvironment = AMPAppMetricaPushEnvironmentProduction;
    #endif
    [AMPAppMetricaPush setDeviceTokenFromData:deviceToken pushEnvironment:pushEnvironment];
}

Alert

AppMetrica allows you to send push notifications to Sandbox APNs. However, push notification processing may not work correctly if versions of the application with different environments were run on the device(development and production). To avoid this issue, you can use a separate test API key for development environment.

Step 4. Configure handling the opening of push notifications

Configure handling the opening of push notifications:

  1. Use the delegate UserNotificationCenterDelegate/AMPUserNotificationCenterDelegate. It handles the receipt of push notifications automatically when they're opened.

    Make the following changes to the code:

    import UserNotifications
    
    // In the "func application(_ application: UIApplication, didFinishLaunchingWithOptions
    //                          launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool" method:
    let delegate = AppMetricaPush.userNotificationCenterDelegate
    UNUserNotificationCenter.current().delegate = delegate
    
    #import <UserNotifications/UserNotifications.h>
    
    // In the   "- (BOOL)application:(UIApplication *)application
    // didFinishLaunchingWithOptions:(NSDictionary *)launchOptions" method:
    [UNUserNotificationCenter currentNotificationCenter].delegate =
            [AppMetricaPush userNotificationCenterDelegate];
    

    To track push notification openings and other actions with them, create your own delegate named UNUserNotificationCenterDelegate and add it to nextDelegate:

    AppMetricaPush.userNotificationCenterDelegate.nextDelegate = yourDelegate
    
    [AMPAppMetricaPush userNotificationCenterDelegate].nextDelegate = yourDelegate;
    

    After that, you can use the appropriate methods of your delegate.

  2. If you also use UISceneDelegate, add the following code to the scene(_:willConnectTo:options:) method:

    func scene(_ scene: UIScene, willConnectTo
               session: UISceneSession, options
               connectionOptions: UIScene.ConnectionOptions) {
         AppMetricaPush.handleSceneWillConnectToSession(with: connectionOptions)
    }
    
    - (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session
          options:(UISceneConnectionOptions *)connectionOptions
    {
        [AMPAppMetricaPush handleSceneWillConnectToSessionWithOptions:connectionOptions];
    }
    

Step 5. (Optional) Enable push tokens update

The APNS service can withdraw the push token of the device, for example, if the user did not launch the application for a long time. AppMetrica stores push tokens on the server and can not send a push notification to a device with an obsolete token.

To automatically collect current push token go to the application settings in the AppMetrica interface and enable the Update tokens with a Silent Push notification option in the Push Notifications tab.

Step 6. (Optional) Configure uploading attached files

Note

The functionality is not available in the web interface of push campaigns.

You can configure uploading attached files in push notifications:

  1. Configure uploading attached files in push notifications by calling the downloadAttachmentsForNotificationRequest method in the Push SDK. See an example of integration in the article Uploading attached files.
  2. Add attachments (the attachments parameter) using the Sending push messages operation in the Push API.

Step 7. (Optional) Set up push notification statistics collection

To collect information about push notification delivery, set up statistics collection by following the instructions.

Sending additional information

You can send additional information with the push notification if necessary. This data is specified in the AppMetrica web interface when configuring the push campaign. To get this information, use the following method:

let userData = AppMetricaPush.userData(forNotification: userInfo)
NSString *userData = [AMPAppMetricaPush userDataForNotification:userInfo];

where userInfo contains information about the push notification.

Defining the recipient of a notification

AppMetrica allows you to detect own push notifications, if several Push SDKs were built into the application.

To detect, if the AppMetrica is the recipient of a notification, use the following method:

let isRelatedToAppMetricaSDK = AppMetricaPush.isNotificationRelated(toSDK: userInfo)
BOOL isRelatedToAppMetricaSDK = [AMPAppMetricaPush isNotificationRelatedToSDK:userInfo];
