Adding buttons to navigation bar ios

Question

I am trying to add two right buttons to the navigation bar. I tried adding using following ways but I get SIGABRT

1. self.navigationController.navigationBar.items = navItemsArray;
2. self.navigationItem.rightBarButtonItems = navItemsArray;

navItemsArray has two buttons of type UIBarButtonItem.

Can anyone help with this? I can't figure out what is wrong.

Answer 1

self.navigationItem.rightBarButtonItems = navItemsArray;

works only in iOS 5.
