I faced same problem some time ago. However not using delegates is not correct way. you should use delegate and control the behaviour depending upon the position.

Make a function in your tableViewCell class, Let's say that's
```
-(void)setMyCellTag:(NSInteger)tag
{
    self.tag = tag;
}
```
Now call this method from your cellForRowAtIndexPath function as,
```
[cell setMyCellTag:indexPath.row];
```

Use condition in UITextField delegate method that,

if(self.tag == yourposition)
{
   //Do Something
}

Simple. Thanks for reading.

let me check it and thanks. – MRizwan33 Apr 02 '18 at 11:32 — MRizwan33, Apr 02 '18 at 11:32

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool
{
    let currentCharacterCount = textField.text?.characters.count ?? 0
    if (range.length + range.location > currentCharacterCount){
        return false
    }
    let newLength = currentCharacterCount + string.characters.count - range.length
    return newLength <= 1 // set your limit
}

make sure textfield delegate
