Question

在涉及推送通知的应用中，我接收设备令牌就好了，但我客户端的设备没有收到设备令牌（因此导致无法接收推送通知）。我正在使用Parse进行推送通知。这就是我AppDelegate中的内容：

-(void)application:(UIApplication *)application
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)newDeviceToken {
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:newDeviceToken];
    PFACL *objectACL = [[PFACL alloc] init];
    [objectACL setPublicReadAccess:YES];
    [objectACL setPublicWriteAccess:YES];

    [currentInstallation saveInBackground];
}

-(void) application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error
{

    NSString *errorString = [NSString stringWithFormat:@"%@", error];
    UIAlertView *errorAlertView = [[UIAlertView alloc] initWithTitle:@"Error" message:errorString delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];

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

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    [Parse setApplicationId:PARSE_APPLICATION_ID
                  clientKey:PARSE_CUSTOMER_KEY];
    [PFFacebookUtils initializeFacebook];

    [self.window makeKeyAndVisible];

    // create the Login controller instance:

    [application registerForRemoteNotificationTypes:
     UIRemoteNotificationTypeBadge |
     UIRemoteNotificationTypeAlert |
     UIRemoteNotificationTypeSound];
}

客户端未收到任何表示未通过APN注册的UIAlert，因此无法调用didFailToRegisterForRemoteNotificationsWithError。我已经尝试从我的解析服务器中删除所有安装，删除了应用程序＆amp;根据Apple技术说明TN2265的指导原则重新安装。该应用程序不会在首次启动时提示客户端授权推送通知。也没有出现在通知中心（这是令人困惑的，因为didRegisterUserNotificationSettings:也存在）。但这一切在我的iPad，iPhone 5S，iPod 5，iPhone 4s上运行良好。任何想法可能导致该设备在应用程序中设备变量行为？这是sc客户端发给我的。notificationCenterScreenShot

尝试以下代码

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

在AppDelegate类的- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法中

Apple推送通知：没有收到设备令牌？
