self.myScrollView.delaysContentTouches = YES;
self.myScrollView.CanCancelContentTouches=NO;
写了一个继承scrollview的类，并在里面实现了touch事件，但是如果要相应touch事件，必须要先让手指在scrollview上停留一会，否则，手指一滑动，直接进scroll的事件了，根本不会触发touch事件。
下面是我在scrollview里面重写的touch事件，那几个NSLog如果手指不停留，更本就不会触发！
-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"PageScrollView Touch begin");
if(!self.dragging)
{
[[self nextResponder] touchesBegan:touches withEvent:event];
}
[super touchesBegan:touches withEvent:event];
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"PageScrollView Touch Move");
if(!self.dragging)
{
[[self nextResponder] touchesMoved:touches withEvent:event];
}
[super touchesMoved:touches withEvent:event];
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"PageScrollView Touch End");
if(!self.dragging)
{
[[self nextResponder] touchesEnded:touches withEvent:event];
}
[super touchesEnded:touches withEvent:event];
}
具体地实现有所不同，需要先将delaysContentTouches设 置为NO，CanCancelContentTouches设置为YES，而后使用- (BOOL)touchesShouldCancelInContentView:(UIView *)view来决定scrollview是否需要滚动。
