// Swift 3 
let backButton = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30)) 
backButton.setBackgroundImage(UIImage(named: "img"), for: .normal) 
backButton.addTarget(self, action: "action:", for: .touchUpInside) 
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: backButton) 

// Swift 2 
let backButton = UIButton(frame: CGRect(x: 0, y: 0, width: 30, height: 30)) 
backButton.setBackgroundImage(UIImage(named: "img"), forState: .Normal) 
backButton.addTarget(self, action: "action:", forControlEvents: .TouchUpInside) 
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: backButton)

// We dont have Property to change UIBarButtonItem frame 
    // So we can creat UIButton() and give requered frame and add to navigationItem.setLeftBarButtonItems 
    // Please refere Belove code

    let btnBack = UIButton()

func createFakeAndSearchCurrentLocationBarButton (vw: UIViewController) { 

    let fakeCurrentLocationGo = UIButton(type: .custom) 
    fakeCurrentLocationGo.setImage(UIImage(named: "reallocationgo50"), for: .normal) 
    fakeCurrentLocationGo.frame = CGRect(x: 0, y: 0, width: 20, height: 20) 
    fakeCurrentLocationGo.addTarget(vw, action: #selector(goToMyCurrentLocationPin), for: .touchUpInside) 
    let leftItem = UIBarButtonItem(customView: fakeCurrentLocationGo) 


    let searchLocationBtn = UIButton(type: .custom) 
    searchLocationBtn.setImage(UIImage(named: "search"), for: .normal) 
    searchLocationBtn.frame = CGRect(x: 0, y: 0, width: 15, height: 15) 
    fakeCurrentLocationGo.addTarget(vw, action: #selector(searchLocationHandle), for: .touchUpInside) 
    let rightItem = UIBarButtonItem(customView: searchLocationBtn) 

    vw.navigationItem.setRightBarButtonItems([leftItem,rightItem], animated: true)
