ios - 我想复制这个导航栏，这个是安卓版的，我该怎么做？

Question

Navigation bar in android which is to be replicated in iOS

图片是我想使用 swift 3 在 ios 中复制的 android 导航栏。我已经为此工作了几天，但我无法正确完成任何帮助。

let height: CGFloat = 128  //whatever height you want
let bounds = self.navigationController!.navigationBar.bounds
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)

我这样做是为了使导航栏的高度正确，但我似乎无法使栏按钮的位置正确。

像这样添加barbutton-

let myBackButton = UIButton(type: .custom)
myBackButton.addTarget(self, action: #selector(backAction), for: UIControlEvents.touchUpInside)
myBackButton.setTitle("YOUR TITLE", for: UIControlState.normal)
myBackButton.setTitleColor(UIColor.blue, for: UIControlState.normal)
myBackButton.sizeToFit()
myBackButton.frame = CGRect(x: 0, y: 0, width: 30, height: 30)
let myCustomBackButtonItem:UIBarButtonItem = UIBarButtonItem(customView: myBackButton)
self.navigationItem.leftBarButtonItem  = myCustomBackButtonItem
