Question

I made a text field but I didn’t use Interface Builder, I did it programmatically in Xcode. So now I need a programmatic way to make it resign first responder so that the keyboard will go away when the user presses enter.

Answer 1

As addition to cobbal’s answer, don’t forget to set text field’s delegate to the class that implements

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
   [textField resignFirstResponder];
   return YES;    
}

Adding descriptor to that class interface declaration is also a good thing.
