Detect Focus Change for UITextField

Question

I\'m trying to set the animation for the view to move up when keyboard is hiding and appearing for the text fields and I got it to work perfectly fine, but when the focus moves

Answer 1

-(BOOL)textFieldShouldBeginEditing:(UITextField*)textField {
if (textField.tag == 1) { //first textField tag
    //textField 1
}
else {
   //textField 2
}
}
