GAD adLoader 代表未被调用

Question

我正在尝试实施原生广告，但 adLoader 委托不会被调用。更有趣的是，委托由于某种原因变成了 nil。没有打印错误，没有收到。任何意见是极大的赞赏。

func getAd(){
let adLoader = GADAdLoader(adUnitID: adUnitID, rootViewController: self, adTypes: [.native], options: [options])
    adLoader.delegate = self
    print(adLoader.delegate)
    adLoader.load(GADRequest())
}
extension ViewController:GADNativeAdDelegate, GADAdLoaderDelegate{
func adLoader(_ adLoader: GADAdLoader, didReceive nativeAd: GADNativeAd) {
    print("did receive")
  // A native ad has loaded, and can be displayed.
}

func adLoaderDidFinishLoading(_ adLoader: GADAdLoader) {
    print("finish Loading")
    // The adLoader has finished loading ads, and a new request can be sent.
}


func adLoader(_ adLoader: GADAdLoader, didFailToReceiveAdWithError error: Error) {
  print(error)
}
}

发现问题..对于将来遇到相同问题的任何人，正确的委托是 GADNativeAdLoaderDelegate 而不是 GADNativeAdDelegate 也不是 GADAdLoaderDelegate
