Question

I have some UITextFields and one button, Can anyone tell me how to make both textfields (first Street Address field and Street Address field below Same As Above button) content equal at the same time if my button (Same As Above) is checked (I m using a boolean variable isSameAsAboveChecked on button click and making value Yes and No on respective actions).

Means If Same As Above button is checked, and i m writing something in First Street Address textfield then at the same time content of Second Street Address text field should start changing. and same for all the other fields.

Thnaks in advance.

Use this delegate method

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
    NSString * toBeString = [textField.text stringByReplacingCharactersInRange:range
                                                                withString:string];
    text2Field.text = toBeString;
    return YES;
}

In it first set the entered text to other textField and then return YES

Dont forget to return yes,
