解决UIScrollView截获touch事件的一个极其简单有效的办法
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。
