Hide UIBarButtonItem from UINavigationBar programatically Swift2

Question

I've tried hiding the thing, but it just appears greyed out in UINavigationController

I found a delete method, but it asks to pass in Anyobject..

Button.delete(AnyObject?)

Answer 1

You can remove the UIBarButtonItem. It's just one type of deallocating the item:

self.navigationItem.rightBarButtonItem = nil

self.navigationItem.leftBarButtonItem = nil
