Since from the IOS7 release there are many UI transition issue developers are facing and working  to fix them worldwide.

one of the UI transition issue which is very common is related with the TAbleView
in IOS7 table view background is white by default and in IOS 6 ,IOS 5 the background is transparent
because of this the table view has become white which is looking bit ugly and Apple have not provided any official document to fix it.

This  problem can be overcome by Overidding the method of TAbleView As follows


- (void)tableView:(UITableView *)tableView
  willDisplayCell:(UITableViewCell *)cell
forRowAtIndexPath:(NSIndexPath *)indexPath
{
    [cell setBackgroundColor:[UIColor clearColor]];
}
