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;

仅适用于iOS 5。

Answer 2

do you have callbacks for the buttons? Did you "wire up" the buttons by option-clicking them and dragging them to something?

You need to have the buttons connected to an IBAction.

Answer 3

You cannot add directly two UIBarButtonItem in UINavigationBar . But use UIToolBar to have same effect as of Navigation Bar. You can add any controls in UIToolBar Such as switch, segmentedControl etc.
