Comment gérer les notifications à distance d'iOS lorsque l'application est en arrière-plan ?

Question

Je travaille sur la fonctionnalité de notification push d'iOS par le biais de la notification push d'apple, pour l'instant je reçois une notification appropriée lorsque mon application est en arrière-plan ou au premier plan, mais je veux gérer la notification à distance lorsque mon application est en arrière-plan fondamentalement, lorsque mon application est en arrière-plan, elle montre simplement le message d'alerte de la charge utile.

code :

 - (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {
// Override point for customization after application launch.
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0)
{
//        [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge) categories:nil]];
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
else
{
[[UIApplication sharedApplication] registerForRemoteNotificationTypes:
(UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert)];
}
return YES;
}
- (void)application:(UIApplication *)application
didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{
NSLog(@"Did Register for Remote Notifications with Device Token (%@)", error);
}
- (void)application:(UIApplication )application didRegisterForRemoteNotificationsWithDeviceToken:(NSData )deviceToken {
NSLog(@"Did Register for Remote Notifications with Device Token (%@)", deviceToken);
}
-(void)application:(UIApplication )application didReceiveRemoteNotification:(NSDictionary )userInfo fetchCompletionHandler:(void (UIBackgroundFetchResult))completionHandler
{
NSDictionary * aps=[userInfo valueForKey"aps"];
NSLog(@"did recevie %@",aps);
NSLog(@"userinfo details %@",[aps valueForKey"alert"]);
}

Dans iOS 10, vous devez d'abord définir UNUserNotificationCenterDelegate sur AppDelegate.h fichier

@interface AppDelegate : UIResponder <UIApplicationDelegate,CLLocationManagerDelegate,UNUserNotificationCenterDelegate>

Après cela, dans AppDelegate.m écrire le code comme ceci

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.1) {
            // iOS 7.1 or earlier. Disable the deprecation warnings.
            UIRemoteNotificationType allNotificationTypes =
            (UIRemoteNotificationTypeSound |
             UIRemoteNotificationTypeAlert |
             UIRemoteNotificationTypeBadge);
            [application registerForRemoteNotificationTypes:allNotificationTypes];
            [[UIApplication sharedApplication] registerForRemoteNotifications];
        } else {
            // iOS 8 or later
            // [START register_for_notifications]
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 9.0)
    {
                UIUserNotificationType allNotificationTypes =
                (UIUserNotificationTypeSound | UIUserNotificationTypeAlert | UIUserNotificationTypeBadge);
                UIUserNotificationSettings *settings =
                [UIUserNotificationSettings settingsForTypes:allNotificationTypes categories:nil];
                [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
                [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
                [[UIApplication sharedApplication] registerForRemoteNotifications];
                [application registerForRemoteNotifications];
            } else {
                // iOS 10 or later
    #if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
                UNAuthorizationOptions authOptions =
                UNAuthorizationOptionAlert
                | UNAuthorizationOptionSound
                | UNAuthorizationOptionBadge;
                [[UNUserNotificationCenter currentNotificationCenter]
                 requestAuthorizationWithOptions:authOptions
                 completionHandler:^(BOOL granted, NSError * _Nullable error) {
                 }
                 ];
                // For iOS 10 display notification (sent via APNS)
                [[UNUserNotificationCenter currentNotificationCenter] setDelegate:self];            
    [[UIApplication sharedApplication] registerForRemoteNotifications];
         return YES;
}

Maintenant, mettez en œuvre cette méthode pour la version iOS10 ci-dessous

    - (void)application:(UIApplication *)application
    didReceiveRemoteNotification:(NSDictionary *)userInfo
    fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {
        NSLog(@"Notification received: %@", userInfo);
        if( SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO( @"10.0" ) )
        {
            NSLog( @"iOS version >= 10. Let NotificationCenter handle this one." );
            return;
        }
        NSLog( @"HANDLE PUSH, didReceiveRemoteNotification: %@", userInfo );
          else{
            handler( UIBackgroundFetchResultNewData );
}

    }

Apple introduit ces deux méthodes dans iOS10 pour recevoir des notifications push.

Écrivez également ces méthodes

    // Receive displayed notifications for iOS 10 devices.
    #if defined(__IPHONE_10_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_10_0
    - (void)userNotificationCenter:(UNUserNotificationCenter *)center
           willPresentNotification:(UNNotification *)notification
             withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler {

        NSDictionary *userInfo = notification.request.content.userInfo;

        NSLog(@"%@", userInfo);

            completionHandler( UNNotificationPresentationOptionAlert );
   }

-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{

    NSLog(@"Userinfo %@",response.notification.request.content.userInfo);
//    completionHandler(UNNotificationPresentationOptionAlert);
       }

C'est tout.
