#pragma mark 在这里做一些初始化配置（比如添加子控件）

#pragma mark 在这里设置子控件的位置和尺寸
- (void)placeSubviews

}

#pragma mark 监听scrollView的contentOffset改变
- (void)scrollViewContentOffsetDidChange:(NSDictionary *)change

}

#pragma mark 监听scrollView的contentSize改变
- (void)scrollViewContentSizeDidChange:(NSDictionary *)change

}

#pragma mark 监听scrollView的拖拽状态改变
- (void)scrollViewPanStateDidChange:(NSDictionary *)change
{
    [super scrollViewPanStateDidChange:change];
    
}

#pragma mark 监听控件的刷新状态
- (void)setState:(MJRefreshState)state
