How do I get a reference to UI elements in a storyboard view from the view's controller?

Question

I have a button and two text fields on the login screen of an app I'm writing.

When I use the "Go" button on my popup keyboard (or hit enter - it's in the simulator) I have a reference to the UITextField and use it to authenticate my users. It hits this method:

- (IBAction)getPassword:(UITextField *)sender {
[self setPassField:sender];

}

When I use the "Login" button, I am not getting a reference to the password text field and authentication fails every time (empty string is not the password).

Is there a way to get a handle on my fields from my view controller so I do not have to rely on field-driven events to get field references?

You need to create two outlets in your view controller: one for the username text field and one for the password text field. You need to connect the outlets to the fields in your storyboard.
