When app is running and it receive push notification then didReceive is called.
func userNotificationCenter(
_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler: @escaping () -> Void
)
So when above delegate is called then i present a screen using the payload i receive. There is no problem here.
When app is not running and user tap the notification then it should present the same screen like above. It's not working because i didn't added a code in didFinishLaunchingWithOptions.
So, then i added the following code -
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
......
if let userInfo = launchOptions?[UIApplication.LaunchOptionsKey.remoteNotification] as? [AnyHashable: Any] {
......
}
return true
}
But this is not working and i cannot debug because when in debug mode i have to kill the app from background and tap the notification but in this case the debugger won't work. I tried alternative method i.e. showing alert but then alert is also not working
let aps = remoteNotif["aps"] as? [AnyHashable: Any]
let string = "\n Custom: \(String(describing: aps))"
let string1 = "\n Custom: \(String(describing: remoteNotif))"
DispatchQueue.main.asyncAfter(deadline: .now() + 5) { [weak self] in
if var topController = application.windows.first?.rootViewController {
while let presentedViewController = topController.presentedViewController {
topController = presentedViewController
}
let ac = UIAlertController(title: string1, message: string, preferredStyle: .alert)
ac.addAction(UIAlertAction(title: "OK", style: .default))
topController.present(ac, animated: true)
}
}
How should i solve this problem ?
I have solved it by implementing sceneDelegate willConnectTo
method. There is no need to handle it in didFinishLaunchingWithOptions
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
//Remote notification response
if let response = connectionOptions.notificationResponse{
print(response.notification.request.content.userInfo)
}
....
}
This is enough
