AppDelegate未侦听APNS推送通知

当我的应用进入后台时，AppDelegate未侦听来自APNS的新推送通知。但奇怪的是，它不会一直发生。有时它起作用，有时它不起作用。我无法弄清楚为什么。AppDelegate未侦听APNS推送通知

下面是用于收听APNS通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 8.0) 
    { 
     UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:(UIRemoteNotificationTypeBadge 
                          |UIRemoteNotificationTypeSound 
                          |UIRemoteNotificationTypeAlert) categories:nil]; 
     [[UIApplication sharedApplication] registerUserNotificationSettings:settings]; 
    } 
    else 
    { 
     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert)]; 
    } 

    if (launchOptions != nil) 
    { 
     NSDictionary *dictionary = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey]; 
     if (dictionary != nil) 
     { 
     } 
    } 
    return YES; 
} 

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo 
{ 
    NSLog(@"Received notification: %@", userInfo); 
    [self application:application didReceiveRemoteNotification:userInfo fetchCompletionHandler:nil]; 
} 

-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler 
{ 
    NSLog(@"Received notification background: %@", userInfo); 
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 5 * NSEC_PER_SEC), 
        dispatch_get_main_queue(), ^{ 
         // Check result of your operation and call completion block with the result 
         completionHandler(UIBackgroundFetchResultNewData); 
        }); 
} 

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings { 
    [application registerForRemoteNotifications]; 
}

在背景/闭合模式下我的示例代码，没有代码将执行并且没有委托方法将是invoked.This时间推送通知由OS本身处理。应用徽章由来自服务器端的推送通知负载值设置。 如果你没有得到在后台程序的徽章，这是从服务器side.Check徽章数量问题的推送通知的有效载荷是否包含应用领域的徽章，并设置为值大于0

This link较大的有同样的问题，解决它。

服务器端发送通知内容可用：1和应用程序应该从服务器获取数据。但是，didReceiveRemoteNotification没有被调用 - 但它并不是一直发生的。有时候，它可以工作。我不明白这一点。顺便说一句，谢谢你的回复。 – user3781953 2014-10-08 09:08:17

didReceiveRemoteNotification将只在应用程序处于运行状态且没有代码在后台状态下执行时调用。如何了解某个时间其工作？ – 2014-10-08 09:32:24

我把日志行放在applicationDidEnterBackground中，这样我就知道应用何时进入后台状态。并且在didReceiveRemoteNotification中有一个日志行来打印通知，有时我可以在日志中看到通知。 – user3781953 2014-10-08 10:06:52

试图改变自己的行..

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) { 
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeAlert|UIUserNotificationTypeSound categories:nil]]; 
} else { 
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeAlert|UIRemoteNotificationTypeBadge|UIRemoteNotificationTypeSound]; 
}

在iOS的8

你必须使用 “UIUserNotificationTypeBadge” ......

希望这会为你工作..
