try like this may be it helps to you,
1.take one global variable type integer for example position.
2.when you click on particular button -(void)buttonclicked:(UIButton *)sender method will call in this method you will assign the btn.tag value to the position .
3.after that you are reloading the table view in the tableview cellForRowAtIndexPath method take one condition like
if(position==indexpath.row)
{
//add your textfield here
}.
