I've successfuly subclassed ABTableViewCell for fast scrolling. I really recommend it to anyone who's making an app with big tableViews...

My problem with it is that when I tap a row, there is a small delay until it gets selected. I tried to put [cell setSelected:true] in the didSelectRowAtIndexPath method of the tableView, and it still lags. Has anyone experienced this as well with a ABTableViewCell subclass?
I didn't have this issue using regular UITableViewCells.
