Ios 解析-只有一个设备接收推送通知，而其他设备不接收'；t、 。。。

我注册了推送通知，它在我的iphone上运行良好。。。我收到所有推送通知。。。但当我在ipad mini上运行应用程序时。。。什么也没发生。PN是允许的，但iPad的deviceToken不会显示在数据浏览器下。。。我能做什么？我做错了什么？这是我的密码：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [Parse setApplicationId:@"UbrfAs5qZsm1JnIsKVH79OtuOfleWxxV98LTXAHI"
                  clientKey:@"oHEKHzfaV0fkaPGaes2M0H0sQfaWiSnzYCU5lIu1"];
    [PFAnalytics trackAppOpenedWithLaunchOptions:launchOptions];

     [application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge|
     UIRemoteNotificationTypeAlert|
     UIRemoteNotificationTypeSound];


    // Override point for customization after application launch.
    return YES; }
      - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    // Store the deviceToken in the current installation and save it to Parse.
    PFInstallation *currentInstallation = [PFInstallation currentInstallation];
    [currentInstallation setDeviceTokenFromData:deviceToken];
    [currentInstallation saveInBackground]; }

     - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    [PFPush handlePush:userInfo]; }
