这两个不能同时使用吗？最初，我在我的 ViewController 中覆盖了 (Swift) touchesBegan/Moved/Ended。
现在，我想在特定情况下将 TapGestureRecognizer 添加到特定 View ，但永远不会触发选择器/操作。
class ViewController: UIViewController, UIGestureRecognizerDelegate {
...
func addTapGesturesOnNumberPadDisplay() {
if tapGestureRecognizerNumberPadView == nil {
tapGestureRecognizerNumberPadView = UITapGestureRecognizer(target: self, action: "handleTap:")
tapGestureRecognizerNumberPadView!.delegate = self
self.numberViewDone?.addGestureRecognizer(tapGestureRecognizerNumberPadView!)
}
}
...
func handleTap(sender: UITapGestureRecognizer) {
//never hit
这不可能吗？我是否应该只在 touchesBegan 中实现自己的点击功能，因为无论如何我都会覆盖它，还是有办法在这里也使用 tapGestureRecognizer？
最佳答案
由于您在 View Controller 中覆盖了 touchesBegan/Moved/Ended，因此它不应该对其他 subview 中的点击手势产生任何影响。理想情况下它应该工作。请检查下面的代码，按预期工作。
class ViewController: UIViewController, UIGestureRecognizerDelegate {
@IBOutlet weak var categoryScrollView: UIScrollView!
var customView: UIView!
var tapGestureRecognizerNumberPadView : UITapGestureRecognizer?
override func viewDidLoad() {
super.viewDidLoad()
customView = UIView()
customView.frame.origin = CGPointMake(50,50)
customView.frame.size = CGSizeMake(100, 100)
customView.backgroundColor = UIColor.blueColor()
self.view.addSubview(customView)
addTapGesturesOnNumberPadDisplay()
}
func addTapGesturesOnNumberPadDisplay() {
if tapGestureRecognizerNumberPadView == nil {
tapGestureRecognizerNumberPadView = UITapGestureRecognizer(target: self, action: "handleTap:")
tapGestureRecognizerNumberPadView!.delegate = self
self.customView?.addGestureRecognizer(tapGestureRecognizerNumberPadView!)
}
}
func handleTap(sender: UITapGestureRecognizer) {
print("handleTap")
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
请检查“numberViewDone” View 是否有任何其他手势。
关于objective-c - 我不能使用 touchesBegan/Moved/Ended 和 UITapGestureRecognizer，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35152443/
