背景显示在子类FUIAuthPickerViewControll

问题描述

因此,出于自定义目的,我将FUIAuthPickerViewController细分为子类,但无法显示背景.在将Firebase Pod更新到最新版本(在先前版本上运行良好)之后,这种情况开始发生.

So, I subclassed FUIAuthPickerViewController for customization purposes but I can't get the background to display. This started happening after updating Firebase pods to the latest version (was working fine on the previous version).

这是我当前的设置.

我怎么称呼它(来自AppDelegate):

How I call it (from AppDelegate):

var authViewController = authUI.authViewController()
self.window!.rootViewController = authViewController
self.window!.makeKeyAndVisible()

我的FUIAuth的委托方法(也在AppDelegate中):

My FUIAuth's delegate method (also in AppDelegate):

func authPickerViewController(forAuthUI authUI: FUIAuth) -> FUIAuthPickerViewController {
    return AuthViewController(authUI: authUI)
}

我的子类:

class AuthViewController: FUIAuthPickerViewController {

    var imgView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let backgroundImage = #imageLiteral(resourceName: "MainBackground")
        imgView = UIImageView(image: backgroundImage)
        imgView.contentMode = .scaleAspectFill
        self.view.insertSubview(imgView, at: 0)
    }

    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

        imgView.frame = self.view.bounds
    }
}

它是什么样的:

如果我将上面的行从以下位置更改:

If I change the line above from:

self.view.insertSubview(imgView, at: 0)

self.view.insertSubview(imgView, at: 1)

然后我可以看到背景而不是按钮:

Then I can see the background and not the buttons:

我在这里想念什么?
