在 iOS swift 中设计导航栏

我想设计一个导航视图。

1. 左侧菜单，标题居中

2. Left Menu 和 Image 就在它旁边，还有左侧按钮

我正在尝试添加这样的按钮，但按钮没有正确显示

func addMenuButton(){

        let btn_menu = UIButton(frame: CGRect(x: 0, y: 0, width: 40, height: 44))
        btn_menu.addTarget(self, action: #selector(self.refreshBtnClicked), for: .touchUpInside)
        btn_menu.setImage(#imageLiteral(resourceName: "ic_menu"), for: .normal)
        btn_menu.setImage(#imageLiteral(resourceName: "ic_menu"), for: .selected)
        self.navigationController?.navigationItem.leftBarButtonItems = [UIBarButtonItem(customView: btn_menu)]
    }

//Option 1
self.title = "Title Here"
self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named: "menu"), style: .plain, target: self, action: #selector(menuBtnAction(_:)))
//Option 2
let plusBtn = UIBarButtonItem(image: UIImage(named: "plus"), style: .plain, target: self, action: #selector(plusBtnAction(_:)))
let logoView = UIImageView(image: UIImage(named:"ins"))
logoView.translatesAutoresizingMaskIntoConstraints = false
logoView.widthAnchor.constraint(equalToConstant: 180).isActive = true
self.navigationItem.leftBarButtonItems = [plusBtn,UIBarButtonItem(customView: logoView)]
