How to move focus on to a Textfield after an alertView from another textField

Question

In my add contact page, am validating my email textfield , phone number fields, etc. And am checking valid email on clicking all other textfields. So when i click on the phone number field, it will check email validity and show an alertview if email is invalid. So when i click ok button in the alertView, the cursor should go to the email textfield instead of being in the phone number field.. Can anyone help on this..?

Answer 1

in alertview's delegate method,

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if([alertView isEqual:emailAlert])//emailAlert should be the instance variable
    {
       if(buttonIndex == 0)//assumes ok button index is 0
       {
             [textfield becomeFirstResponder];
       }
    }
}
