Reference
* Due to there are more functions of this framework,Don't write specific text describe its usage
* You can directly reference examples MJTableViewController、MJCollectionViewController、MJWebViewController,More intuitive and fast.

The drop-down refresh 01-Default
self.tableView.mj_header = [MJRefreshNormalHeader headerWithRefreshingBlock:^{
//Call this Block When enter the refresh status automatically
}];
