重点关注UIButton时，Siri Remote的菜单按钮未退出应用程序 [英] Siri Remote's Menu Button not exiting application when UIButton is focused

问题描述

我要覆盖pressesBegan以接收Select印刷机.当焦点位于UIButton上时，Siri Remote的菜单按钮不会退出我的应用程序.如果没有将UI元素作为焦点，则菜单按钮将按预期工作.

I'm overriding pressesBegan to receive Select presses. The Siri Remote's Menu Button does not exit my application when the focus is on a UIButton. If no UI element is focused the Menu Button works as expected.

当焦点位于UIButton上时如何接收菜单按钮按下?

How do I receive Menu Button presses when the focus is on a UIButton?

override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) {
    for item in presses {
        if item.type == .Select {
            print("Click")
        }
        if item.type == .Menu {
            print("Menu Button")
            super.pressesBegan(presses, withEvent: event)
        }
    }
}

推荐答案

UIButton仅响应遥控器上的.Select按钮.您可以使用点击手势识别器来捕捉菜单按钮.例如:

UIButton only responds to the .Select button on the remote. You can catch the menu button using a tap gesture recognizer. For example:

let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(ClassName.menuPressed()))
tapRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.Menu.rawValue)];
view.addGestureRecognizer(tapRecognizer)

然后执行:

func menuPressed() {
    // do something
}
