1. Set Tag to your textfields

2. Implement UITextFieldDelegate in your class

3. Use this methods

   - (void)textFieldDidBeginEditing:(UITextField *)textField {
       if (textField.tag == your tag) {
           selectedTextField = textField; //selectedTextField is an UITextfield variable
       }
   }
   

4. Use it in your IBAction

   - (IBAction)buttonPressed:(UIButton *)sender {
       selectedTextField.text = @"abc";
   }
