实现view手势点击响应
在UIViewController中,加入协议UIGestureRecognizerDelegate,然后.m文件里加入以下代码:
UITapGestureRecognizer* singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
[self.view addGestureRecognizer:singleTap];
//这个可以加到任何控件上,比如你只想响应WebView,我正好填满整个屏幕
singleTap.delegate = self;
singleTap.cancelsTouchesInView = NO;
[singleTap release];
然后有一个关键的,要实现一个方法:
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
最后,响应的方法中,可以获取点击的坐标哦!
-(void)handleSingleTap:(UITapGestureRecognizer *)sender
{
CGPoint point = [sender locationInView:self.view];
NSLog(@"handleSingleTap!pointx:%f,y:%f",point.x,point.y);
}
