手势冲突的解决方法

UIGestureRecognizerDelegate两三事：

-(BOOL)gestureRecognizer:(UIGestureRecognizer*)gestureRecognizer shouldReceiveTouch:(UITouch*)touch {

if([touch.view isKindOfClass:[UIButton class]])

return NO;//不会执行UIGestureRecognizer注册的事件

else

return YES;//会执行UIGestureRecognizer注册的事件

//或者下边这种方式也可以。
CGPoint location = [touch locationInView:self];
if(CGRectContainsPoint(某个冲突button.frame, location)){
return NO;
}
return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;//UIScrollView 和 子View上的UIPanGestureRecognizer都会响应
return NO;//只响应子View上的UIPanGestureRecognizer
}
