Summary:
In iOS 7 and prior there were various ways to hide the buttons on a navigationBar in a ABPeoplePickerNavigationController. None of these seem to work any more in iOS 8.0.2 (have not tested with 8.1).

I wanted to have the ABPeoplePickerNavigationController contained within a UIView of another controller, and therefore didn't need an additional Cancel button. I ended up refactoring the UI to dispay the picker in a modal.

Steps to Reproduce:
1. Instantiate and display a ABPeoplePickerNavigationController
2. Attempt to hide buttons in the navigationBar. 
	a) One way is to set your controller to be a UINavigationControllerDelegate, in `func navigationController(nav: UINavigationController, willShowViewController viewController:UIViewController, animated:Bool)` you used to be able to set the UIBarButtonItems to nil or a view with a frame of CGRectZero.
	b) I believe there is a private api called `setAllowsCancel(_: bool)`.

Expected Results:
The UIBarButtonItems are removed (or hidden)

Actual Results:
The UIBarButtonItems are visible.

Version:
iOS 8.0.2
