问题描述
我正在构建一个iPhone应用程序，让用户重新排列屏幕上的一些UI元素。
I'm building an iPhone app that would let the user rearrange some of the UI elements on the screen.
如何在同一个UIView中添加轻击手势识别器和长按手势识别器？当我从长按中抬起手指时，轻敲手势识别器会触发。如何在用户执行长按时暂时禁用点击手势识别器或阻止其触发？
How can I add a tap gesture recognizer and a long press gesture recognizer to the same UIView? When I lift up the finger from the long press, the tap gesture recognizer fires. How can I temporarily disable the tap gesture recognizer or prevent it from firing when the user is performing a long press?
谢谢！
推荐答案
要允许两个手势一起使用，请实现以下委托方法：
To allow both gestures to work together, implement the following delegate method:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
为了使长按具有第一优先权，请执行：
To make it so that the long press has first priority, do:
[tapGesture requireGestureRecognizerToFail：longPress];
