在Xcode 8 / Swift 3.0中注冊推送通知？我正在嘗試讓我的應用程序在Xcode 8.0中運行，并且遇到了錯誤。我知道這個代碼在以前版本的swift中運行良好，但我假設在新版本中更改了代碼。這是我正在嘗試運行的代碼：let settings = UIUserNotificationSettings(forTypes: [.Sound, .Alert, .Badge], categories: nil) UIApplication.sharedApplication().registerUserNotificationSettings(settings)UIApplication.shared().registerForRemoteNotifications()我得到的錯誤是“參數(shù)標簽”（forTypes：，categories :)'與任何可用的重載都不匹配“是否有一個不同的命令，我可以嘗試使其工作？
