Question

I am using this function:

- (BOOL)textField:(UITextField *)textField 
      shouldChangeCharactersInRange:(NSRange)range 
      replacementString:(NSString *)string 
{
}

Inside the above function I want to check which textfield I am currently dealing with, can I put a check on on that particular textfield and secondly I want to compare say textfieldB.text when I end editing it (textfieldB) to another field say textfieldA.text, are the above two scenarios possible, I appreciate in advance for any help

Answer 1

If these are IBOutlets and declared in your interface then you can have if statements to check which textfield you are dealing with (i.e if(textField == textFieldA){doSomething;}
else if (textField ==…

Also if the textFieldA are tagged (you an tag them in interface builder) then you can have a switch statement to test each case.
Switch (textField.tag){…}.

You should also make you UIViewController class a “UITextFieldDelegate” and you can call a similar – (void)textFieldDidEndEditing… And make a similar comparison there.

I hope this helps
