UITableView显示图片错误

使用GCD从网上加载图片到UITableViewCell中，但是显示的图片不对。

代码：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
    UITableViewCell *cell = [self.newsTable dequeueReusableCellWithIdentifier:@"newsTableCell"];
    NSString *user = [usernames objectAtIndex:[indexPath row]];
    NSString *stat = [statistics objectAtIndex:[indexPath row]];
    NSString *imagePath = [appDelegate.URL stringByAppendingString:@"ImageName"];
    UIImageView *userImageView = (UIImageView *)[self.view viewWithTag:80];
        NSString *imagePath1 = [imagePath stringByAppendingString:[imagepaths objectAtIndex:[indexPath row]]];
        NSURL *url = [NSURL URLWithString:imagePath1];
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul);
    dispatch_async(queue, ^{
        NSData *data = [NSData dataWithContentsOfURL:url];
        UIImage *img = [[UIImage alloc] initWithData:data];
        userImageView.layer.cornerRadius = 5.0;
        userImageView.layer.masksToBounds = YES;
         dispatch_sync(dispatch_get_main_queue(), ^{
        [userImageView setImage:img];
         });
    });
 return cell
}

请帮忙看一下哪里的图片不对，谢谢。

解决方案

没看到你把图片赋值给 cell

不知道对不对？
