How to display buttons on navigation bar in UIPageViewController? - ios

Question

I'm using a UIPageViewController connected to a UINavigationController to display two pages, a users table and a chat table.
I'm trying to implement the following:
Two buttons Users and Chat upon tapping which, the corresponding view controller appears. I want these buttons on the navigation bar.
Here's the code I've written in the page view controller class
viewDidLoad()
let storyBoard = UIStoryboard(name: "Main", bundle: nil)
let vc1 = storyBoard.instantiateViewControllerWithIdentifier("users")
let vc2 = storyBoard.instantiateViewControllerWithIdentifier("chat")
vcArray = [vc1, vc2]
self.setViewControllers([vc1], direction: .Forward, animated: true, completion: nil)
let button1 = UIButton(frame: CGRectMake(0, 30, self.view.frame.width/2, 30))
let button2 = UIButton(frame: CGRectMake(self.view.frame.width/2+1, 30, self.view.frame.width/2, 30))
button1.setTitle("Users", forState: .Normal)
button2.setTitle("Chat", forState: .Normal)
self.navigationController?.navigationBar.topItem?.titleView?.addSubview(button1)
self.navigationController?.navigationBar.topItem?.titleView?.addSubview(button2)
Unfortunately, none of the buttons appears in the navigation bar.
In fact, I can't even assign a title to the navigation bar. How can I fix this?
Thanks

You can add multiple button on the right side of navigation bar like this
let editImage = UIImage(named: "First")!
let searchImage = UIImage(named: "Second")!
let editButton = UIBarButtonItem(image: editImage, style: .Plain, target: self, action: "didTapEditButton:")
let searchButton = UIBarButtonItem(image: searchImage, style: .Plain, target: self, action: "didTapSearchButton:")
navigationItem.rightBarButtonItems = [editButton, searchButton]
or
self.navigationController?.navigationBar?.navigationItem.rightBarButtonItems = [editButton, searchButton]
If you want to make it look in the centre on the navigation bar, you
can use image with appropriate width so that it scales towards the center.
