Question

我在Swift iOS项目的视图控制器中实现了一个智能横幅广告，这似乎完美无缺。代码如下：

let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)

self.view.addSubview(bannerView)

bannerView.delegate = self
bannerView.adUnitID = "ca-app-pub-xyz..."
bannerView.rootViewController = self

let request = GADRequest()
request.testDevices = [kGADSimulatorID, "my-iphone-device-id"]
bannerView.load(request)

我现在想在我项目的另一个视图控制器中做同样的事情。最简单的解决方案是简单地将上面的代码复制粘贴到新的控制器中，这样可以正常工作。

我宁愿不这样做，因为拥有我的iPhone "my-iphone-device-id"的测试ID字符串的多个副本似乎不是最佳做法。是否有更好的方法来存储此ID，以便我的项目中的所有控制器都可以访问它，而不必将字符串复制粘贴到任何地方？

Answer 1

在整个应用程序中将此类用于Centralizing AdBanner。

如何使用

// Set bannerViewAdUnitID = Your Banner Id First in below class

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        SwiftyAd.shared.showBanner(from: self)
    }

Answer 2

是否有更好的方法来存储此ID，以便我的所有控制器项目可以访问它，而无需复制粘贴字符串到处都是吗？

当然有。 Google gives you two options如何请求测试广告。

有两种获取测试广告的方法：



使用Google的示例广告单元之一。



使用您自己的广告单元并启用测试设备。

恕我直言，不要麻烦测试设备ID。只需请求带有示例广告单元的测试广告即可。

添加具有以下内容的 Constants.swift 类：

static var adUnitID: String {
        #if DEBUG
            return "ca-app-pub-3940256099942544/2934735716"
        #else
            return "my production ad unit"
        #endif
    }

并且在您的请求中：

let bannerView = GADBannerView(adSize: kGADAdSizeSmartBannerPortrait)
bannerView.adUnitID = Constants.adUnitID

我为Google横幅广告指南编写了扩展程序，以动态显示和隐藏横幅，检测连接丢失并使用正确的智能横幅Opon旋转，也许这也有帮助：https://github.com/soenkegissel/ShowAndHideAdBanner
