基础使用

//防止循环引用
__weak UITableView *tableView = self.tableView;
__weak typeof(self)weakSelf = self;

 MJRefreshNormalHeader *header = [MJRefreshNormalHeader headerWithRefreshingTarget:self refreshingAction:@selector(refreshHouseData)];
 MJRefreshNormalHeader *header = [MJRefreshNormalHeader headerWithRefreshingBlock:^{
       [weakSelf refreshHouseData];
   }];
tableView.mj_header = header;

//自定义文字
[header setTitle:@"下拉刷新" forState:MJRefreshStateIdle];
[header setTitle:@"松开就可以刷新的状态" forState:MJRefreshStatePulling];
[header setTitle:@"正在努力刷新中...." forState:MJRefreshStateRefreshing];
[header setTitle:@"刷新完毕，没有更多数据" forState:MJRefreshStateNoMoreData];

header.lastUpdatedTimeLabel.hidden = NO;//隐藏上次更新时间
header.stateLabel.hidden = NO;// 隐藏状态

//设置字体
header.stateLabel.font = [UIFont systemFontOfSize:15];
header.lastUpdatedTimeLabel.font = [UIFont systemFontOfSize:15];

//设置颜色
header.stateLabel.textColor = [UIColor redColor];
header.lastUpdatedTimeLabel.textColor = [UIColor blueColor];

// 设置自动切换透明度(在导航栏下面自动隐藏)
header.automaticallyChangeAlpha = YES;

MJRefreshBackNormalFooter *footer = [MJRefreshBackNormalFooter footerWithRefreshingTarget:self refreshingAction:@selector(loadMoreHouseData)];
MJRefreshBackNormalFooter *footer = [MJRefreshBackNormalFooter footerWithRefreshingBlock:^{
        [weakSelf loadMoreHouseData];
    }];
tableView.mj_footer = footer;

[footer setTitle:@"上拉加载" forState:MJRefreshStateIdle];
[footer setTitle:@"松开就可以加载的状态" forState:MJRefreshStatePulling];
[footer setTitle:@"正在努力加载中...." forState:MJRefreshStateRefreshing];
[footer setTitle:@"加载完毕，没有更多数据" forState:MJRefreshStateNoMoreData];

 // 拿到当前的上拉刷新控件，变为没有更多数据的状态
 [tableView.mj_footer endRefreshingWithNoMoreData]
//隐藏当前上拉刷新控件 ，隐藏后就没有刷新控件
 tableView.mj_footer.hidden = YES;

简单动画

 tableView.mj_header = [MJRefreshGifHeader headerWithRefreshingBlock:^{
        [weakSelf refreshHouseData];
    }];
[header setImages:imageArr1  forState:MJRefreshStateIdle];
[header setImages:imageArr2  forState:MJRefreshStateRefreshing];

webView

 __weak UIWebView *webView = self.webView;    
 __weak UIScrollView *scrollView = self.webView.scrollView;
    
 // 添加下拉刷新控件
 scrollView.mj_header= [MJRefreshNormalHeader headerWithRefreshingBlock:^{
        [webView reload];
  }];

#pragma mark - webViewDelegate
- (void)webViewDidFinishLoad:(nonnull UIWebView *)webView
{
    [self.webView.scrollView.mj_header endRefreshing];
}
