1.MJRefresh基本介绍
使用MJRefresh进行刷新操作，根据需求进行是否分页，从而进行下拉刷新和上拉加载更多；MJRefresh的github地址：https://github.com/CoderMJLee/MJRefresh

下拉刷新和上拉加载之MJRefresh篇：https://www.jianshu.com/p/9b7b86d23a63
- 刷新控件的状态：
typedef NS_ENUM(NSInteger, MJRefreshState) {// 刷新控件的状态
MJRefreshStateIdle = 1,// 普通闲置状态
MJRefreshStatePulling,// 松开就可以进行刷新的状态
MJRefreshStateRefreshing,// 正在刷新中的状态
MJRefreshStateWillRefresh,// 即将刷新的状态
MJRefreshStateNoMoreData// 所有数据加载完毕，没有更多的数据了
};
2.演示Demo如下：
效果图：
下拉-MJRefreshStateIdle
下拉-MJRefreshStatePulling
下拉-MJRefreshStateRefreshing
上拉-MJRefreshStateIdle
上拉-MJRefreshStateRefreshing
上拉-MJRefreshStateNoMoreData
