didReceiveRemoteNotification non appelée, iOS 10

Question

Dans iOS 9.3, la méthode didReceiveRemoteNotification est appelée aux deux occasions suivantes.

1) Lorsque la notification Push est reçue 2) Lorsque l'utilisateur lance l'application en appuyant sur la notification.

Mais sur iOS 10, je remarque que la méthode didReceiveRemoteNotification ne PAS se déclenche lorsque l'utilisateur lance l'application en appuyant sur la notification. Il n'est appelé que lorsque la notification est reçue. Par conséquent, je ne peux plus rien faire après le lancement de l'application à partir de la notification.

Quel devrait être le correctif pour cela? Une idée?

    return true
}

  for i in 0..<deviceToken.count {

AppDelegate.h a ces lignes:

Étape 1

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

Étape 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)  

Étape 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;
}

Cela se déclenchera à la suite de l'appel de registerForRemoteNotifications:

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

Ensuite, lorsqu'un utilisateur appuie sur une notification, cela déclenche:

Cela se déclenche sous iOS 10 lorsque l'application est au premier plan ou en arrière-plan, mais n'est pas fermée

 -(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 );  
}  
}  

ou utiliser

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

Puis pour iOS 10, ces deux méthodes:

- (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
   }

Answer 2

J'ai eu le même problème. La bannière de notification est apparue, mais la méthode -application:didReceiveRemoteNotification:fetchCompletionHandler: n’a pas été appelée. La solution pour moi qui a fonctionné a été d'ajouter l'implémentation de la méthode - application:didReceiveRemoteNotification: et de transférer l'appel à -application:didReceiveRemoteNotification:fetchCompletionHandler::

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

Answer 3

C'est un bug iOS. Il sera corrigé dans iOS 10.1. Mais attendez la publication de la version 10.1 en octobre au lieu d’implémenter une nouvelle bibliothèque et supprimez-la plus tard.

code Swift:

    // Override point for customization after application launch.

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

    // ...

    return true

Version de travail iOS 11, Swift 4, Xcode 9. Il suffit de copier-coller le code ci-dessous dans AppDelegate.

import UIKit
import UserNotifications
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate {

    var window: UIWindow?


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

Answer 6

BTW, ce problème semble être résolu dans iOS 10.1. J'ai testé mon application sur 10.1, tout fonctionne bien

Answer 7

Swift 4 et IOS 12.

Bien qu'il puisse y avoir plusieurs raisons (déjà mentionnées dans d'autres réponses) pour expliquer ce problème, dans mon cas, la solution était liée à la charge utile lors de l'envoi de la notification Push:

Vous devez définir la clé "content-available" sur la charge utile json sur 1.

par exemple:

{"aps": {"alert": "Test", "content-available": 1 , "badge" : 1, "son": "par défaut"}}

Answer 8

Swift 4, Si vous utilisez version de iOS 11 ou xcode supérieure à 9., vous devez avoir la méthode délégué UNUserNotification pour appeler le didReceiveRemoteNotification

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

//Your code to handle events

}
