MJRefresh实现上下拉加载(自定义动画)

自定义header

NSMutableArray *headerImages = [NSMutableArray array];
    for (int i = 1; i <= 4; i++) {
        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"topload%d",i]];
        [headerImages addObject:image];
    }
    MJRefreshGifHeader *gifHeader = [MJRefreshGifHeader headerWithRefreshingBlock:^{
//下拉刷新要做的操作.
    }];
    gifHeader.stateLabel.hidden = YES;
    gifHeader.lastUpdatedTimeLabel.hidden = YES;
    
    [gifHeader setImages:@[headerImages[0]] forState:MJRefreshStateIdle];
    [gifHeader setImages:headerImages forState:MJRefreshStateRefreshing];
    _tableView.header = gifHeader;
    

自定义footer

    NSMutableArray *footerImages = [NSMutableArray array];
    for (int i = 1; i <= 4; i++) {
        UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"footerload%d",i]];
        [footerImages addObject:image];
    }
    MJRefreshAutoGifFooter *gifFooter = [MJRefreshAutoGifFooter footerWithRefreshingBlock:^{
//上拉加载需要做的操作.
    }];
    
    gifFooter.stateLabel.hidden = YES;
    gifFooter.refreshingTitleHidden = YES;
    [gifFooter setImages:@[footerImages[0]] forState:MJRefreshStateIdle];
    [gifFooter setImages:footerImages forState:MJRefreshStateRefreshing];
    _tableView.footer = gifFooter;
