我正在实现自定义UIGestureRecognizer。为简单起见，假设它识别包含>1次触摸的手势。这是Gesture.m:#import"Gesture.h"#import#defineSHOWprintf("%s%d%d%d\n",__FUNCTION__,self.state,touches.count,self.numberOfTouches)@implementationGesture-(void)touchesBegan:(NSSet*)toucheswithEvent:(UIEvent*)event{SHOW;if(self.numberOfTouches==1)retu

我正在检测用户是否按下了2秒:UILongPressGestureRecognizer*longPress=[[UILongPressGestureRecognizeralloc]initWithTarget:selfaction:@selector(handleLongPress:)];longPress.minimumPressDuration=2.0;[selfaddGestureRecognizer:longPress];[longPressrelease];这就是我处理长按的方式:-(void)handleLongPress:(UILongPressGestureRecogn
