我想删除UIView用户点击除该视图之外的其他内容后从屏幕上显示。 （为了让您形象化，我将上传我的视图草图）
我想去掉蓝色UIView用户点击此视图中除按钮之外的其他内容后。我应该用什么？
编辑：
穿蓝色衣服UIView有两个按钮，我想在用户点击背景图像时删除该视图
我做了 @yerpy 告诉我的事情，但它不起作用。
func test(gestureRecognizer: UITapGestureRecognizer) {
print("test")
}
func setUpBackgroundImageView() {
self.view.addSubview(backgroundImageView)
backgroundImageView.widthAnchor.constraint(equalTo: view.widthAnchor).isActive = true
backgroundImageView.heightAnchor.constraint(equalTo: view.heightAnchor).isActive = true
backgroundImageView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
backgroundImageView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
let tap = UITapGestureRecognizer(target: self, action: #selector(test(gestureRecognizer:)))
backgroundImageView.addGestureRecognizer(tap)
tap.delegate = self
}
我还添加shouldReceiveTouch功能为UIGestureRecognizerDelegate。我究竟做错了什么？
Add UIGestureRecognizer to the super view :
正如你所说，你有图像视图作为背景。
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(tapped(gestureRecognizer:)))
imageView.addGestureRecognizer(tapRecognizer)
tapRecognizer.delegate = self
添加目标动作：
func tapped(gestureRecognizer: UITapGestureRecognizer) {
// Remove the blue view.
}
然后里面UITapGestureRecognizerDelegate :
extension ViewController : UIGestureRecognizerDelegate {
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool {
if touch.view!.superview!.superclass! .isSubclass(of: UIButton.self) {
return false
}
return true
}
}
希望能帮助到你 ！
EDIT
确保用户可以触摸view通过启用：self.view.userInteractionEnabled = true
