如何在swift ios中使用导航栏标题中的图像

我有麻烦了。我想在导航栏标题中使用图像，但我得到一个错误，即“UIImage”不是“NSString”的子类型。下面的代码，看看它

class Dashboard: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.title = UIImage(named: "logo.png")        
    // Do any additional setup after loading the view.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

有人能建议吗？谢谢

设置navigationItem的标题视图

var image = UIImage(named: "logo.png")
self.navigationItem.titleView = UIImageView(image: image)

为我工作

        let image : UIImage = UIImage(named: "headerLogo")
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 25, height: 25))
    imageView.contentMode = .scaleAspectFit
    imageView.image = image
    navigationItem.titleView = imageView

Swift 5+，iOS 13+

navigationItem.titleView = UIImageView(image: UIImage(named: "id_logo"))

无法将UIImage类型的对象分配给NSString。navigationItem的标题只能保存文本数据（NSString）。
