当UIScrollView将touch事件截获时，我们可以要写个UIScrollView的类别，把事件从UIScrollView传出去！

@implementation UIScrollView (UITouch)
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //if(!self.dragging)
    {
        [[self nextResponder] touchesBegan:touches withEvent:event];
    }
    [super touchesBegan:touches withEvent:event];
}
-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event
{
    //if(!self.dragging)
    {
        [[self nextResponder] touchesMoved:touches withEvent:event];
    }
    [super touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    //if(!self.dragging)
    {
        [[self nextResponder] touchesEnded:touches withEvent:event];
    }
    [super touchesEnded:touches withEvent:event];
}
@end

然后重写nextResponder的touch方法就可以了。
