I am using navigation controller, and I\'ve set to true its navigation bar\'s prefersLargeTitle
property. Everything works fine, but when the text of my title becom
This is the workaround that I found
override func viewDidLoad() {
super.viewDidLoad()
title = yourTitle
adjustLargeTitleSize()
}
extension UIViewController {
func adjustLargeTitleSize() {
guard let title = title, #available(iOS 11.0, *) else { return }
let maxWidth = UIScreen.main.bounds.size.width - 60
var fontSize = UIFont.preferredFont(forTextStyle: .largeTitle).pointSize
var width = title.size(withAttributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: fontSize)]).width
while width > maxWidth {
fontSize -= 1
width = title.size(withAttributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: fontSize)]).width
}
navigationController?.navigationBar.largeTitleTextAttributes =
[NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: fontSize)
]
}
}
