问题
I'm using Interface Builder.
In my XIB file I have a UIView that I'm using as a "container" view to hold my UITextFields.
I have three UITextField in that UIView.
They are all wired up to an IBOutlet and the delegate for each is wired to the File's Owner.
Everything in Interface Builder has 'User Interaction Enabled' checked.
I can select, meaning click on to bring up the keyboard, the top two UITextFields.
When I click on the third (bottom) UITextField, nothing happens. The keyboard will not appear.
I can programmatically set it to becomeFirstResponder, but when I click on it via Simulator, or tap on it via device, nothing happens.
What could I be overlooking?

Make sure that your third UITextField or given delegate connection in file owner's. and make sure that your third Textfield is inside your current view.
