objective-c - 推送一条信息，收到多条重复推送（5条）

Question

1. 描述你的问题
   我在云端推送一条消息，有两台设备，iOS9.2和iOS7.3，9.2收到5条重复数据，7.3正常收到一条数据，这让我非常困惑，有大神能指点下吗。

2. 贴上相关代码
   注册推送代码如下：

—— (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

// 注册推送
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert categories:nil];
    [application registerUserNotificationSettings:settings];
    [application registerForRemoteNotifications];
}  else {
    UIRemoteNotificationType myTypes = UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound;
    [application registerForRemoteNotificationTypes:myTypes];
}
}

실패했는지 확인하려면 돌아가세요. 단, 클라이언트에서는 병합 알림 ID를 확인해야 합니다
