Try this code may be helped you...
Add the spinner directly to the cell view felt a little hacky, so I used a 1x1 transparent png as the image view and resized it to be whatever my spinner size is:
UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"NoReuse"] autorelease];
cell.textLabel.text = #"Loading...";
UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc]
initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray] autorelease];
// Spacer is a 1x1 transparent png
UIImage *spacer = [UIImage imageNamed:#"spacer"];
UIGraphicsBeginImageContext(spinner.frame.size);
[spacer drawInRect:CGRectMake(0,0,spinner.frame.size.width,spinner.frame.size.height)];
UIImage* resizedSpacer = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
cell.imageView.image = resizedSpacer;
[cell.imageView addSubview:spinner];
[spinner startAnimating];
return cell;
That gives a cell that looks like this:
