我正在使用 AFNetworking 从服务器下载图像,一切正常,但除非我滚动表格视图,否则图像不会出现。这是我的代码:
   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
        static NSString *CellIdentifier = @"Cell";
        UITableViewCell*cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
//configuring news feed
    dictionary = [newsFeed objectAtIndex:indexPath.row];
 //display thumbnails
    UIImageView *image = [[UIImageView alloc]init];
    [image setImageWithURL:[NSURL URLWithString:[dictionary objectForKey:@"image"]]placeholderImage:[UIImage imageNamed:NEWSAVATAR]];
    cell.imageView.image = [image.image imageScaledToSize:CGSizeMake(55, 55)];
    [cell setNeedsLayout];
    return cell;
}
