尝试在iOS 8.x下注册推送通知时:
application.registerForRemoteNotificationTypes(UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound)
我收到以下错误:
registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.
任何想法是什么新的做法？当我在iOS 7.x上运行这个Swift应用程序时,它确实有效.

在iOS 7.x上,当我包含我得到的条件代码时(SystemVersion条件或#if __IPHONE_OS_VERSION_MAX_ALLOWED> = 80000)
