Swift - 从 GADBannerView 扩展后出现无法识别的选择器错误

Question

我想构建像其他 View 一样扩展 GADBannerView 的自定义类，但它不起作用

class ListAd:GADBannerView {
    var controller: UIViewController?

    convenience init(hostView: UIView, controller: UIViewController) {
        self.init(frame: hostView.bounds)
        self.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        self.translatesAutoresizingMaskIntoConstraints = false
        self.controller = controller
        hostView.addSubview(self)
    }

    func loadAd() {
        if APP.displayBannerAd {
            self.adUnitID = ADMOBIDS["banner"]
            self.rootViewController = controller
            self.load(GADRequest())
        }
    }
}

然后我初始化它

admobBanner = ListAd(hostView: self.view, controller: self)
admobBanner?.loadAd()

出现错误:

[App.ListAd setAdUnitID:]:无法识别的选择器发送到实例 0x7fe7f9c04d60'

尝试调用 init(adSize: GADAdSize, origin: CGPoint) 或 init(adSize: GADAdSize) 而不是 self.init(frame:)
