UIScrollView touches事件不响应解决

//重写UIScrollView的以下三个方法，通过“类别”扩展或是继承自UIScrollView自定义类实现。

 

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