objective-c - 推一則訊息，收到多個重複推播（5個）

Question

1. 描述你的問題
   我在雲端推送一條訊息，有兩台設備，iOS9.2和iOS7.3，9.2收到5條重複數據，7.3正常收到一條數據，這讓我非常困惑，有大神能指點下嗎。

2. 貼上相關程式碼
   註冊推播程式碼如下：

—— (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];
}
}

返回確認不成功吧。然而客戶端應該檢查合併通知的id呀
