Description
This is a duplicate of rdar://25550491
Summary: When overriding
-[UIViewController navigationItem]as documented and returning a custom navigation item, that item is ignored if the view controller is instantiated in a storyboard as the root view controller of a navigation controller.Pushing it from inside a storyboard works as expected.Steps to Reproduce:
Expected Results: The navigation bar shows a bar button item with the title ‘Test’ on the right side.
Actual Results: The navigation bar has no items at all.
Regression: This issue does not occur if the view controller in question is pushed onto a navigation controller. It doesn’t matter if it is the result of a storyboard segue or a programatic call to
pushViewController:animated:. It works in both cases.Notes: The documentation is a little vague is it only states ‘To ensure the navigation item is configured, you can either override this property and add code to create the bar button items when first accessed or create the items in your view controller's initialization code.’ It is unclear to me if overriding also means returning an instance of
UINavigationItemthat I created myself, but that is how I understand that. If this is not what this means that please treat this radar as a) a bug report for the documentation and b) a request that having custom navigation items should be possible. As it already works in almost all cases, it may already be fixed by asking fornavigationItemwhile being initialized through a coder instead of directly accessing the internal ivar.Radar Sample Code can be found here: https://github.com/PSPDFKit-labs/radar.apple.com/tree/master/25550491%20-%20OverridingNavigationItemStoryboardFails
