Apple 推送通知：未收到设备令牌？

Question

在一个涉及推送通知的应用程序中，我可以很好地接收设备令牌，但我客户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。这就是我的 AppDelegate:

-(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];
}

客户端没有收到任何表示 APN 注册失败的 UIAlert，这意味着 didFailToRegisterForRemoteNotificationsWithError 没有被调用。我已尝试从我的解析服务器中删除所有安装，删除应用程序并根据 Apple 技术说明 TN2265 的指导再次重新安装。该应用程序不会在首次启动时提示客户端授权推送通知，也不会出现在通知中心（这令人困惑，因为 didRegisterUserNotificationSettings: 也在那里）。但所有这一切在我的 iPad、iPhone 5S、iPod 5、iPhone 4s 上运行良好。有什么想法可能导致此设备在应用程序中出现设备变量行为吗？！这是 sc 客户端发给我的。notificationCenterScreenShot

试试下面的代码

    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)];
    }

在您的 AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法中 class
