didReceiveRemoteNotification nicht aufgerufen, iOS 10

In iOS 9.3 wird die didReceiveRemoteNotificationMethode bei beiden folgenden Gelegenheiten aufgerufen.

1) Wenn die Push-Benachrichtigung empfangen wird 2) Wenn der Benutzer die App durch Tippen auf die Benachrichtigung startet.

Unter iOS 10 stelle ich jedoch fest, dass die didReceiveRemoteNotificationMethode NICHT ausgelöst wird, wenn der Benutzer die App durch Tippen auf die Benachrichtigung startet. Es wird nur aufgerufen, wenn die Benachrichtigung empfangen wird. Daher kann ich keine weiteren Aktionen ausführen, nachdem die App von der Benachrichtigung aus gestartet wurde.

Was sollte das Problem beheben? Irgendeine Idee?

Beispiel siehe hier

Importieren Sie das UserNotificationsFramework und fügen Sie das UNUserNotificationCenterDelegatein Appdelegate hinzu

import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate  


func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    //create the notificationCenter
    let center  = UNUserNotificationCenter.current()
    center.delegate = self
    // set the type as sound or badge
    center.requestAuthorization(options: [.sound,.alert,.badge,  .providesAppNotificationSettings]) { (granted, error) in
        // Enable or disable features based on authorization

        }
        application.registerForRemoteNotifications()

    return true
}


 func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
 // let chars = UnsafePointer<CChar>((deviceToken as NSData).bytes)
  var token = ""

  for i in 0..<deviceToken.count {
//token += String(format: "%02.2hhx", arguments: [chars[i]])
   token = token + String(format: "%02.2hhx", arguments: [deviceToken[i]])
  }

  print("Registration succeeded!")
  print("Token: ", token)
 }

 func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
  print("Registration failed!")
 }

Erhalten Sie die Benachrichtigungen mit diesen Delegaten

 func userNotificationCenter(_ center: UNUserNotificationCenter,  willPresent notification: UNNotification, withCompletionHandler   completionHandler: @escaping (_ options:   UNNotificationPresentationOptions) -> Void) {
    print("Handle push from foreground")
    // custom code to handle push while app is in the foreground
    print("\(notification.request.content.userInfo)")
 }

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print("Handle push from background or closed")
    // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background
    print("\(response.notification.request.content.userInfo)")
}

func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {
let navController = self.window?.rootViewController as! UINavigationController
let notificationSettingsVC = NotificationSettingsViewController()
navController.pushViewController(notificationSettingsVC, animated: true)
}

Ziel c

AppDelegate.h hat folgende Zeilen:

Schritt 1

//Add Framework in your project "UserNotifications"
#import <UserNotifications/UserNotifications.h>  
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>  

Schritt 2

AppDelegate.m

  // define macro
  #define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)  
  #define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)  

Schritt 3

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
application.applicationIconBadgeNumber = 0;
    if( SYSTEM_VERSION_LESS_THAN( @"10.0" ) ) {  
        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound |    UIUserNotificationTypeAlert | UIUserNotificationTypeBadge |  UIUserNotificationTypeprovidesAppNotificationSettings) categories:nil]];  
        [[UIApplication sharedApplication] registerForRemoteNotifications];  

        //if( option != nil )  
        //{  
        //    NSLog( @"registerForPushWithOptions:" );  
        //}  
    } else {  
      UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];  
      center.delegate = self;  
      [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if( !error ) {
            // required to get the app to do anything at all about push notifications  
            [[UIApplication sharedApplication] registerForRemoteNotifications];
            NSLog( @"Push registration success." );  
        } else {
            NSLog( @"Push registration FAILED" );  
            NSLog( @"ERROR: %@ - %@", error.localizedFailureReason, error.localizedDescription );  
            NSLog( @"SUGGESTIONS: %@ - %@", error.localizedRecoveryOptions, error.localizedRecoverySuggestion );  
        }
        }];
    }

    return YES;
}

Dies wird durch den Aufruf von registerForRemoteNotifications ausgelöst:

 - (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken  
{  
// custom stuff we do to register the device with our AWS middleman  
 }

Wenn ein Benutzer auf eine Benachrichtigung tippt, wird Folgendes ausgelöst:

Dies wird in iOS 10 ausgelöst, wenn sich die App im Vordergrund oder im Hintergrund befindet, aber nicht geschlossen ist

 -(void) application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void  
  (^)(UIBackgroundFetchResult))completionHandler  
  {  
// iOS 10 will handle notifications through other methods  

if( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ) )  
{  
  NSLog( @"iOS version >= 10. Let NotificationCenter handle this one." );  
 // set a member variable to tell the new delegate that this is background  
  return;  
}  
NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );  

// custom code to handle notification content  

if( [UIApplication sharedApplication].applicationState == UIApplicationStateInactive )  
{  
  NSLog( @"INACTIVE" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
else if( [UIApplication sharedApplication].applicationState == UIApplicationStateBackground )  
{  
  NSLog( @"BACKGROUND" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
else  
{  
  NSLog( @"FOREGROUND" );  
  completionHandler( UIBackgroundFetchResultNewData );  
}  
}  

oder verwenden

  - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo  
{  
[self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result) {  
}];  
}  

Dann für iOS 10 diese beiden Methoden:

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
    willPresentNotification:(UNNotification *)notification  
  withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler  
    {  
  NSLog( @"Handle push from foreground" );  
  // custom code to handle push while app is in the foreground  
    NSLog(@"%@", notification.request.content.userInfo);
   }  

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
didReceiveNotificationResponse:(UNNotificationResponse *)response  
  withCompletionHandler:(void (^)())completionHandler  
   {  
     NSLog( @"Handle push from background or closed" );  
     // if you set a member variable in didReceiveRemoteNotification, you  will know if this is from closed or background  
     NSLog(@"%@", response.notification.request.content.userInfo);
    }  

    - (void)userNotificationCenter:(UNUserNotificationCenter *)center 
   openSettingsForNotification:(UNNotification *)notification{
        Open notification settings screen in app
   }

Ich hatte das gleiche Problem. Das Benachrichtigungsbanner wurde angezeigt, die -application:didReceiveRemoteNotification:fetchCompletionHandler:Methode wurde jedoch nicht aufgerufen. Die Lösung für mich bestand darin, die Implementierung der - application:didReceiveRemoteNotification:Methode hinzuzufügen und den Aufruf an -application:didReceiveRemoteNotification:fetchCompletionHandler:folgende Adresse weiterzuleiten :

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:^(UIBackgroundFetchResult result){}];
}

Swift 4 und IOS 12.

Obwohl es mehrere Gründe geben kann (bereits in anderen Antworten erwähnt), warum dieses Problem auftreten könnte, hing die Lösung in meinem persönlichen Fall mit der Nutzlast beim Senden der Push-Benachrichtigung zusammen:

Sie müssen den Schlüssel "Inhalt verfügbar" auf dem JSON festlegen Nutzlast auf 1.

zB:

{"aps": {"alert": "Test", "content-available": 1 , "badge": 1, "sound": "default"}}

Schneller Code :

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.

    if #available(iOS 10.0, *) {
        let center = UNUserNotificationCenter.currentNotificationCenter()
        center.delegate = self
    }

    // ...

    return true
}

@available(iOS 10.0, *)
public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {        
    print(response.notification.request.content.userInfo)        
}

@available(iOS 10.0, *)
public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    print(notification.request.content.userInfo)
}

Es ist ein iOS-Fehler. Es wird in iOS 10.1 behoben. Warten Sie jedoch auf die Veröffentlichung von 10.1 im Oktober, anstatt eine neue Bibliothek zu implementieren, und entfernen Sie sie später.

Übrigens scheint dieses Problem in iOS 10.1 behoben zu sein. Ich habe meine App auf 10.1 getestet, alle funktionieren einwandfrei

Swift 4: Wenn Sie eine iOS 11- oder Xcode-Version größer als 9.0 verwenden , müssen Sie die Delegierungsmethode UNUserNotification verwenden, um die didReceiveRemoteNotification aufzurufen

  func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {

//Your code to handle events

}
