重写-handlePan:在UIScrollView中

如果有人感兴趣,我所做的不是重写,而是禁用默认的UIPanGestureRecognizer,并添加映射到我的自定义处理程序的UIPanGestureRecognizer的另一个实例。

为twerdster编辑:

//disables the built-in pan gesture
for (UIGestureRecognizer *gesture in scrollView.gestureRecognizers){
  if ([gesture isKindOfClass:[UIPanGestureRecognizer class]]){
    gesture.enabled = NO;
  }
}

//add your own
UIPanGestureRecognizer *myPan = [[UIPanGestureRecognizer alloc] init...];
//customize myPan here
[scrollView addGestureRecognizer:myPan];
[myPan release];

//disables the built-in pan gesture
scrollView.panGestureRecognizer.enabled = NO;

//add your own
UIPanGestureRecognizer *myPan = [[UIPanGestureRecognizer alloc] init...];
[scrollView addGestureRecognizer:myPan];
[myPan release];
