UITableview单元格在错误的位置显示图像？

Question

嗨我试图显示位置，强度，日期和图像的数组。我在数组中只有2个值，但是在第2行的tableview单元格中出现了2个图像。

请检查图像，您可以看到显示两张图像的同一行。

这是我的代码：

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"Cell";
    cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil) {
        cell = [[BVHistoryTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
    }
    cell.imgView.layer.masksToBounds=YES;
    cell.imgView.layer.cornerRadius=9.0;


    ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
    {
        rep = [myasset defaultRepresentation];
        iref = [rep fullResolutionImage];
        if (iref) {
            largeimage = [UIImage imageWithCGImage:iref];
            cell.imgView.image = largeimage;//Display image
        }
    };

    ALAssetsLibraryAccessFailureBlock failureblock  = ^(NSError *myerror)
    {
        NSLog(@"Can't get image - %@",[myerror localizedDescription]);
    };

     asseturl = [NSURL URLWithString:[img objectAtIndex:indexPath.row]];
     library = [[ALAssetsLibrary alloc] init] ;
     [library assetForURL:asseturl
                    resultBlock:resultblock
                   failureBlock:failureblock];
    //  cell.imageView.image=[UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[img objectAtIndex:0]]]];
    cell.location.text = [latitude objectAtIndex:indexPath.row];
    cell.intensity.text=[intensity objectAtIndex:indexPath.row];
    cell.dates.text=[date objectAtIndex:indexPath.row];
    return cell;
}
