shouldChangeCharactersInRange affecting all UITextField's

I have two UITextField in my app, one is for price and the other is a label for a product.

I have defined both UITextField's with @property and @synthesize into the .m

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

I'm using this method to limit the entry for the price field but it seems to be affecting both field. How to limit it to one field?

The method is called when any of the UITextFields have this instance set as a delegate in Interface Builder or with code. You can check which field calls it with something like:

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if(textField == yourSynthesizedPropertyForPriceField) {
        //DO SOMETHING
    }
    return YES;
}
