用Swift编程隐藏Admob广告

Question

我的浏览广告是从viewDidLoad

加载的

override func viewDidLoad() {
        super.viewDidLoad()
            let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
            bannerView.frame = CGRect(x: 0.0,
                                      y: UIApplication.sharedApplication().statusBarFrame.size.height,
                                      width: bannerView.frame.width,
                                      height: bannerView.frame.height)
            bannerView.adUnitID = "ca-app-pub-myID"
            bannerView.rootViewController = self
            bannerView.loadRequest(GADRequest())
            view.addSubview(bannerView)
    }

我正在尝试使用以下功能隐藏广告：

func removeAds () {
        let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
        bannerView.removeFromSuperview()
    }

但是，这不起作用。我犯了什么错？

Answer 1

您正在此处创建全新的AdView实例

func removeAds () {
        let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
        bannerView.removeFromSuperview()
    }

您需要为视图加载

上方的当前类定义全局AdView实例

您可以使用以下代码

来实现此目的

var bannerView : GADBannerView!

override func viewDidLoad() {
        super.viewDidLoad()
           bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
            bannerView.frame = CGRect(x: 0.0,
                                      y: UIApplication.sharedApplication().statusBarFrame.size.height,
                                      width: bannerView.frame.width,
                                      height: bannerView.frame.height)
            bannerView.adUnitID = "ca-app-pub-myID"
            bannerView.rootViewController = self
            bannerView.loadRequest(GADRequest())
            view.addSubview(bannerView)
    }

您可以使用

删除该addView

func removeAds () {
        bannerView.removeFromSuperview()
    }
