Adding a Navigation Controller but navigation item not displaying - ios

Question

Originally I had a custom NavigationBar, without a navigation controller. I have a sliding menu.
On the home screen there is a tableview, with a list. I would like to be able to add items to this list. So, I had to add in a navigation controller after the fact. I added the navigation controller to the storyboard and linked it to my main view controller [the one with the list]. Then I dragged in a view controller. I dropped in a bar button item into the navigation item, and pushed it to the recently added view controller.
I ran my app and the app shows no navigation bar or navigation item whatsoever now. Originally I had a custom navigation bar.
I'm not too sure what's going on here. Thanks for any help.

Here are all the arrays I use

From the image you are showing, it doesn't look like any of the VCs have the starting arrow to its left. If that is the case, go to SB, click on the Nav controller, go to Attributes inspector on the right,scroll down and check the "Is initial View Controller".
Hope this answers it.
Update: Guessing at your code, you are trying to modify an immutable NSArray. Change your declaration to NSMutableArray *toDoList.
