NSString *copyStringverse = [[NSString alloc] initWithFormat:@"%@",[textview.text]];
UIPasteboard *pb = [UIPasteboard generalPasteboard];
[pb setString:copy
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!";
For Swift 3.x
UIPasteboard.general.string = "String to copy"
For Swift 2.1+:
let cell = tableView.cellForRowAtIndexPath(indexPath) as! UITableViewCell // change this to your custom cell if you use one
UIPasteboard.generalPasteboard().string = cell.textLabel.text
For Swift2.2
UIPasteboard.generalPasteboard().string = tableViewCell.textLabel.text
By using this you can directly set the value to UIPasteboard
