iphone - 滚动表格 View 后出现图像 (AFNetworking)

Question

我正在使用 AFNetworking 从服务器下载图像，一切正常，但图像不会出现，除非我滚动表格 View 。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;
}

Answer 1

试试这个

[ cell.imageView.image  setImageWithURL:[NSURL URLWithString:[dictionary objectForKey:@"image"]]placeholderImage:[UIImage imageNamed:NEWSAVATAR]];
