cell.textLabel.text = [arryData objectAtIndex:indexPath.row];
return cell;

Answer 1

You can do it in your didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Changing button label
[_btn setTitle:[arryData objectAtIndex:indexPath.row] forState:UIControlStateNormal];
// Hiding table view
flag=1;
tblSimpleTable.hidden=YES;
i.hidden=NO;
}
