#import "TableViewCell.h"#import "ImageModal.h"// 下载图片(MRC)#import "UIImageView+WebCache.h"@implementation TableViewCell#pragma mark - 给cell赋值方法- (void)setCellModal:(ImageModal *)modal{    // 第三方 可以付动态图    [self.pictureImageView sd_setImageWithURL:[NSURL URLWithString:modal.imageUrlString] placeholderImage:[UIImage imageNamed:@"5.png"]];}cellForRowAtIndexPath// cellForRowAtIndexPath- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{    static NSString *cellIdentifier = @"TableViewCell";    TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];    ImageModal *modal = self.dataArray[indexPath.row];    [cell setCellModal:modal];    cell.titleLabel.text = modal.title;    return cell;}

利用第三方 MBProgressHUD
