Question

Is it possible to get the title text to shrink to fit in the UINavigationBar in iOS.

(for portrait iPhone app with no autolayout).

Answer 1

I used this code for swift 4 (note label rect is NOT important..)

func navBar()->UINavigationBar?{
        let navBar = self.navigationController?.navigationBar
        return navBar
    }


override func viewDidLoad() {
        super.viewDidLoad()

        setTNavBarTitleAsLabel(title: "VERYYYY VERYYYY VERYYYY VERYYYY VERYYYY VERYYYY VERYYYY LONGGGGGG")
    }

    // will shrink label...

    func setTNavBarTitleAsLabel(title: String, color: UIColor ){

        // removed some code..

        let navigationTitlelabel = UILabel(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
        navigationTitlelabel.numberOfLines = 1
        navigationTitlelabel.lineBreakMode = .byTruncatingTail

        navigationTitlelabel.adjustsFontSizeToFitWidth = true
        navigationTitlelabel.minimumScaleFactor = 0.1
        navigationTitlelabel.textAlignment = .center
        navigationTitlelabel.textColor  = color
        navigationTitlelabel.text = title

        if let navBar = navBar(){
            //was navBar.topItem?.title = title

            self.navBar()?.topItem?.titleView = navigationTitlelabel
            //navBar.titleTextAttributes = [.foregroundColor : color ?? .black]
        }
    }
