Answer 1

I had similar issue, but I am using Swift. Here is the answer in Swift 2.2.

        override func viewWillAppear(animated: Bool) {
            let backButton: UIBarButtonItem = UIBarButtonItem(title: "Back", style: .Plain, target: self, action: #selector(back))
            self.navigationItem.leftBarButtonItem = backButton;
            super.viewWillAppear(animated);
        }

        func back() {
            self.dismissViewControllerAnimated(true, completion: nil)
        }
