要忽略触摸事件并将它们传递给另一个子视图的UIControl对象,您可以遵循以下步骤:
hitTest(_:with:)
方法。这个方法用于确定哪个视图应该接收触摸事件。在这个方法中,您可以返回nil,这将忽略触摸事件。touchesBegan(_:with:)
、touchesMoved(_:with:)
、touchesEnded(_:with:)
和touchesCancelled(_:with:)
方法。在这些方法中,您可以将触摸事件传递给另一个子视图。例如:
class MyUIControl: UIControl {
override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
// 忽略触摸事件
return nil
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
// 将触摸事件传递给另一个子视图
let anotherSubview = self.superview?.subviews.first(where: { $0 is AnotherSubview }) as? AnotherSubview
anotherSubview?.touchesBegan(touches, with: event)
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
// 将触摸事件传递给另一个子视图
let anotherSubview = self.superview?.subviews.first(where: { $0 is AnotherSubview }) as? AnotherSubview
anotherSubview?.touchesMoved(touches, with: event)
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
// 将触摸事件传递给另一个子视图
let anotherSubview = self.superview?.subviews.first(where: { $0 is AnotherSubview }) as? AnotherSubview
anotherSubview?.touchesEnded(touches, with: event)
}
override func touchesCancelled(_ touches: Set<UITouch>, with event: UIEvent?) {
// 将触摸事件传递给另一个子视图
let anotherSubview = self.superview?.subviews.first(where: { $0 is AnotherSubview }) as? AnotherSubview
anotherSubview?.touchesCancelled(touches, with: event)
}
}
这样,当MyUIControl对象接收到触摸事件时,它将忽略这些事件并将它们传递给另一个子视图(在这个例子中是AnotherSubview)。
