iOS - UIRemoteNotificationTypeBadge & Push

Question

如果我的应用程序已经启动，并且只启动了。我实现了应用程序:didReceiveRemoteNotification:接收有效载荷。如果消息被发送到我的iPhone，是否对每种注册类型都调用此方法，如下面的方法？

[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:**UIRemoteNotificationTypeNone**]; //1

[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:**UIRemoteNotificationTypeBadge**]; //2

[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:**UIRemoteNotificationTypeSound**];  //3

[[UIApplication sharedApplication]
registerForRemoteNotificationTypes:**UIRemoteNotificationTypeAlert**];  //4

我对解决方案1有很大怀疑..。

Answer 1

该方法只需要调用一次。类型参数是要为其注册的类型的位掩码：

[[UIApplication sharedApplication] registerForRemoteNotificationTypes: UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];

上面的代码将注册徽章和声音远程通知。
