#pragma mark - 重写方法
#pragma mark 在这里做一些初始化配置（比如添加子控件）
- (void)prepare

#pragma mark 在这里设置子控件的位置和尺寸
- (void)placeSubviews
{
    [super placeSubviews];
    self.loading.center = CGPointMake(self.mj_w/2 , self.mj_h * 0.5);
}

#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
