Question

I followed the tutorial

to dismiss the number pad, this tutorial add the button as sub view to the number pad,

my problem is, in the same view i am using the text field to enter text also,so, how to differentiate the number field, and text field. so that i can hide the button view accordingly.

thanks in advance.

Yoy can use UITextFieldDelegate Protocol instead of NSNotifications, and inside methods textFieldDidBeginEditing: and textFieldDidEndEditing: check which field is being used. Something like this:

- (void) textFieldDidBeginEditing:(UITextField *)textField { 
if (textField == self.passwordField) {
  // add subview...
}
