Question

我试图在swift 3.0文件中添加一个admob横幅。我的项目是objc和swift 3.0的组合，但我遇到了问题。

我无法添加GADBannerViewDelegate。关于GADAdSize，GADGender，kGADGenderUnknown之前的声明，我得到了大约20个错误。
如果我无法添加GADBannerViewDelegate，那么我就无法设置delegate = self
我收到以下错误：致命错误：在解包可选值时意外发现nil

这是我的代码：

resultSet.next()

好吧，所以除了谷歌示例中的3行代码之外我已经将所有内容划掉了条纹并且我得到以下错误：致命错误：在解开可选值时意外地发现了nil。我破坏了谷歌的例子，他们没有这个问题，这很奇怪。我没有GADBannerViewDelegate，因为谷歌的例子也没有。

func initAdMobBanner() {

    if UIDevice.current.userInterfaceIdiom == .phone {
        // iPhone
        //adBannerView.adSize =  GADAdSizeFromCGSize(CGSize(width: 320, height: 50))
        //adBannerView.frame = CGRect(x: 0, y: view.frame.size.height, width: view.frame.size.width, height: 50)
    } else  {
        // iPad
        //adBannerView.adSize =  GADAdSizeFromCGSize(CGSize(width: 468, height: 60))
        //adBannerView.frame = CGRect(x: 0, y: view.frame.size.height, width: view.frame.size.width, height: 60)
    }

    adBannerView.adUnitID = kadmobID
    adBannerView.rootViewController = self
    adBannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
    adBannerView.delegate = self
    view.addSubview(adBannerView)

    let request = GADRequest()
    adBannerView.load(request)
}


// Hide the banner
func hideBanner(_ banner: UIView) {
    UIView.beginAnimations("hideBanner", context: nil)
    banner.frame = CGRect(x: view.frame.size.width/2 - banner.frame.size.width/2, y: view.frame.size.height - banner.frame.size.height, width: banner.frame.size.width, height: banner.frame.size.height)
    UIView.commitAnimations()
    banner.isHidden = true
}

// Show the banner
func showBanner(_ banner: UIView) {
    UIView.beginAnimations("showBanner", context: nil)
    banner.frame = CGRect(x: view.frame.size.width/2 - banner.frame.size.width/2, y: view.frame.size.height - banner.frame.size.height, width: banner.frame.size.width, height: banner.frame.size.height)
    UIView.commitAnimations()
    banner.isHidden = false
}

// AdMob banner available
func adViewDidReceiveAd(_ bannerView: GADBannerView!) {
    showBanner(adBannerView)
}

// NO AdMob banner available
func adView(_ bannerView: GADBannerView!, didFailToReceiveAdWithError error: GADRequestError!) {
    hideBanner(adBannerView)
    print("adView:didFailToReceiveAdWithError: \(error.localizedDescription)")

}
