确保viewController嵌入在navigationController中，并编写如下代码

let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 20))
imageView.contentMode = .scaleAspectFill
navigationItem.titleView = imageView
imageView.sd_setImage(with: URL(string: currentFirma?.goruntuUrl ?? ""), placeholderImage: UIImage(named: "")) // make sure to add a placeholder for better UX
