swift - 如何访问 Siri Remote 播放/暂停按钮和覆盖菜单按钮

Question

如何使用 Siri 遥控器访问播放/暂停按钮并覆盖菜单按钮？我目前正在使用它，但它对我不起作用。当我使用此代码时，我的程序崩溃，但仅当我将其称为四个按下暂停按钮的示例时，编码器当前位于 touchesBegan 旁边的 didMoveToView 下方

let tapGesture = UITapGestureRecognizer(target: self, action: "handleTap:")
tapGesture.allowedPressTypes = [NSNumber(integer: UIPressType.Menu.rawValue)]
self.view.addGestureRecognizer(tapGesture)

Answer 1

您的问题是您正在调用一个名为的函数，该函数handleTap:接收一个参数，但您没有一个名为handleTap:. 这就是action这一行中的代表：

let tapGesture = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))

将您更改func tapped()为：

func handleTap(sender: UITapGestureRecognizer) {
    if sender.state == UIGestureRecognizerState.Ended {
        print("Menu button released")
    }
}

Answer 2

我对 Swift 4 使用以下内容（根据问题：@selector() in Swift?）

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(sender:)))
tapGesture.allowedPressTypes = [NSNumber(integer: UIPressType.Menu.rawValue)]
self.view.addGestureRecognizer(tapGesture)

---

@objc func handleTap(sender: UITapGestureRecognizer) {
    if sender.state == UIGestureRecognizerState.Ended {
        print("Menu button released")
    }
}

我通过将tapRecognizer选择器移动到我之前设置的触摸处理程序函数中解决了我的问题，因此代码现在看起来像这样：

private func handleTouches(touches: Set<UITouch>) {
    for touch in touches {
        let touchLocation = touch.locationInNode(self)
        lastTouch = touchLocation

        let tapRecognizer = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
        tapRecognizer.allowedPressTypes = [NSNumber(integer: UIPressType.PlayPause.rawValue)];
        self.view!.addGestureRecognizer(tapRecognizer)
    }
}

func handleTap(sender: UITapGestureRecognizer) {
    if sender.state == UIGestureRecognizerState.Ended {
        print("Menu button released")
    }     
 }
