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];
}
}

Answer 1

返回确认不成功吧。然而客户端应该检查合并通知的id呀

Answer 2

我也遇到了同样的问题，只是收到了两条重复的消息。
我的解决办法是:
把[application registerUserNotificationSettings:settings];注释掉，
只保留[application registerForRemoteNotifications];
