See mine.

1. Adding a UIButton to UIBarbuttonitem.

   self.navigationController?.navigationBarHidden = false
   
   //making a button
   var button: UIButton = UIButton()
   button.setImage(UIImage(named: "person-icon.jpg"), forState: .Normal)
   button.frame = CGRectMake(0, 0, 25, 25)
   button.targetForAction("actioncall", withSender: self)
   button.addTarget(self, action: "actioncall", forControlEvents: UIControlEvents.TouchUpInside)
   
   //making a UIBarbuttonItem on UINavigationBar
   var rightItem:UIBarButtonItem = UIBarButtonItem()
   rightItem.customView = button        
   self.navigationItem.rightBarButtonItem = rightItem
   

2. Initialise a UIBarButtonItem

   let rightNavItem = UIBarButtonItem(image: UIImage(named: "search1x"), landscapeImagePhone: nil, style: UIBarButtonItemStyle.Plain, target: self, action: "actioncall")
   navigationItem.rightBarButtonItem = rightNavItem
   

3. OR

   let rightNavItem = UIBarButtonItem()
   rightNavItem.action = "action call"
   
   
   //Anticipated Method on clicking uibarbuttonitem
   func actioncall(){
   }
