试试这个
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;

UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(205.0f, 0.0f, 44.0f, 44.0f);
spinner.tag = 3;
[cell.contentView addSubview:spinner];
