问题描述
我有一个tvOS应用程序，其中UITabBarController作为主故事板的主要入口点.如果用户未登录，则UITabBarController会模态显示LoginViewController.
I have a tvOS app, with a UITabBarController as the main entry point for the main storyboard. If the user is not logged in, the UITabBarController presents a LoginViewController modally.
当用户按下Siri遥控器上的Menu(菜单)按钮时，系统会自动关闭LoginViewController并显示UITabBarController.我希望该应用程序转而退出tvOS床头板.
When the user presses the Menu button on the Siri remote, the system automatically dismiss the LoginViewController and shows the UITabBarController. I want the app to instead exit to the tvOS headboard.
期望解决方案涉及到UITapGestureRecognizer来覆盖菜单"按钮动作，或者覆盖pressesBegan/pressesTouched，但是我还没有找到解决方案.
Expect the solution to involve either a UITapGestureRecognizer to override the Menu button action, or overriding pressesBegan/pressesTouched, but I haven't found a solution yet.
推荐答案
下面的代码段有效，并且是基于苹果用于遥控器和交互的HIG
This following snippet works, and is acceptable behavior based on the expected behavior for a menu button in Apples HIG for Remotes and Interactions
override func viewDidLoad() {
super.viewDidLoad()
let tapRecognizer = UITapGestureRecognizer(target: self, action: "tapped")
tapRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.Menu.rawValue)];
self.view.addGestureRecognizer(tapRecognizer)
}
func tapped() {
exit(EXIT_SUCCESS)
}
