• Gif : MJRefreshBackGifFooter / MJRefreshAutoGifFooter

使用時(shí)有Block 和 Target-Action兩種模式

基礎(chǔ)使用

//防止循環(huán)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;

//自定義文字
[header setTitle:@"下拉刷新" forState:MJRefreshStateIdle];
[header setTitle:@"松開就可以刷新的狀態(tài)" forState:MJRefreshStatePulling];
[header setTitle:@"正在努力刷新中...." forState:MJRefreshStateRefreshing];
[header setTitle:@"刷新完畢，沒(méi)有更多數(shù)據(jù)" forState:MJRefreshStateNoMoreData];

header.lastUpdatedTimeLabel.hidden = NO;//隱藏上次更新時(shí)間
header.stateLabel.hidden = NO;// 隱藏狀態(tài)

//設(shè)置字體
header.stateLabel.font = [UIFont systemFontOfSize:15];
header.lastUpdatedTimeLabel.font = [UIFont systemFontOfSize:15];

//設(shè)置顏色
header.stateLabel.textColor = [UIColor redColor];
header.lastUpdatedTimeLabel.textColor = [UIColor blueColor];

// 設(shè)置自動(dòng)切換透明度(在導(dǎo)航欄下面自動(dòng)隱藏)
header.automaticallyChangeAlpha = YES;

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

[footer setTitle:@"上拉加載" forState:MJRefreshStateIdle];
[footer setTitle:@"松開就可以加載的狀態(tài)" forState:MJRefreshStatePulling];
[footer setTitle:@"正在努力加載中...." forState:MJRefreshStateRefreshing];
[footer setTitle:@"加載完畢，沒(méi)有更多數(shù)據(jù)" forState:MJRefreshStateNoMoreData];

 // 拿到當(dāng)前的上拉刷新控件，變?yōu)闆](méi)有更多數(shù)據(jù)的狀態(tài)
 [tableView.mj_footer endRefreshingWithNoMoreData]
//隱藏當(dāng)前上拉刷新控件 此再，隱藏后就沒(méi)有刷新控件
 tableView.mj_footer.hidden = YES;

簡(jiǎn)單動(dòng)畫

 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];
}
