background tap - background should have type UIControl and method should be connected to the "touch down" action
textView - doesn't need to be connected to an action, but delegate needs to be connected to something that is a UITextViewDelegate
textField - delegate needs to be connected to something that is a UITextFieldDelegate and method should be connected to the "did end on exit" action
