SDWebImage not showing randomly in UITableViewCell - objective-c

Question

Hello I have a script that downloads an image and dynamically sets the UITableView height after it finishes the download, but some images randomly do not show , the curious think is that when i change back and forth the tab the images suddenly appear . in the options argument i am passing SDWebImageRetryFailed.
Any idea would be more than welcome , thanks.

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

CGSize descHeight = [[[cell newsBody] text] sizeWithFont:[[cell newsBody] font] constrainedToSize:cell.newsBody.frame.size lineBreakMode:[[cell newsBody] lineBreakMode]];

}
Partially solved although solution less than ideal. Since i only needed to show 10 cells I prevented the reuse of the UITableViewCell
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
item = [news objectAtIndex:[indexPath row]];
NSString *identifier = [NSString stringWithFormat:#"Cell %d", indexPath.row];
UINib *nib = [UINib nibWithNibName:#"FrontPageViewNewsCell" bundle:nil];
[[self tableView] registerNib:nib forCellReuseIdentifier:identifier];
cell = [tableView dequeueReusableCellWithIdentifier:identifier];
// cell = [tableView dequeueReusableCellWithIdentifier:#"FrontPageNewsCell"];
still interested in finding a solution reusing cell
Thanks,
