Copy functionality in iOS by using UIPasteboard
Well you don't say exactly how you have your table view cell set up, but if it's just text inside your table view it could be as easy as:
// provided you actually have your table view cell
NSString *copyStringverse = yourSelectedOrClickedTableViewCell.textLabel.text;
UIPasteboard *pb = [UIPasteboard generalPasteboard];
[pb setString:copyStringverse];
[UIPasteboard generalPasteboard].string = @"Copy me!";
