Question

我正试图快速检测出印刷机，我无法检测出印刷机。这是我的代码：

override func pressesBegan(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
    print("test1")
}

override func pressesChanged(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
    print("test2")
}

override func pressesEnded(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
    print("test3")
}

override func pressesCancelled(_ presses: Set<UIPress>, with event: UIPressesEvent?) {
    print("test4")
}

在物理苹果电视和模拟器上执行代码后，控制台仍为空。为什么没有检测到印刷机？任何帮助将不胜感激。

我找到了答案，但我不确定为什么覆盖方法不起作用。

let press:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(pressed))
press.allowedPressTypes = [NSNumber(value: UIPressType.select.rawValue)]
view.addGestureRecognizer(press)

按下没有工作tvos - swift
