我使用电容器社区AdMob（v5.3.1）在Android和iOS应用程序上显示横幅和插播广告。我使用Angular与Ionic框架-代码库是相同的，除了“原生”的东西，如IOS的Info.plist。
我将iPhone和Android手机都设置为AdMob上的测试设备，这样我就可以显示真实的广告（但处于测试模式）。广告在Android手机上显示良好，但在iPhone上不起作用。我一直收到错误“没有广告显示”当尝试显示iPhone广告时。我三次检查我在AdMob中为iPhone设置了正确的IDFA。我正在使用“我的设备标识符”获取IDFA那个应用程序也给了我一个IDFV，但我认为IDFA是正确的ID。
我的AdMob帐户似乎没有任何限制。这是由它为Android提供广告的事实所支持的。
我能够在iPhone和Android上显示演示广告单元。我还发现，如果我在AdMob.initialize步骤中将iPhone添加为测试设备，使用Logcat消息中显示的设备ID（如下所示），我就能够显示测试广告：

2023-12-03 21:08:15.779400+0000 MyTestApp[1707:99269] <Google> To get test ads on this device, set: 
Objective-C
    GADMobileAds.sharedInstance.requestConfiguration.testDeviceIdentifiers = @[ @"770185167e05233828007f06c16a1211" ];

字符串
这是我的initialize方法：

AdMob.initialize({
  testingDevices: environment.testingDevices,
  initializeForTesting: true,
});

型
我使用一个环境变量来存储测试设备ID：

testingDevices: ['770185167e05233828007f06c16a1211','1E80E3909C199A8778EBFB88E5F9DA71']

如果我使用AdMob.initialize方法以编程方式添加测试设备，iPhone测试广告显示OK。当然，在Logcat中使用testDeviceIdentifier的问题是，它会随着应用程序的每次新安装而改变，这就是为什么我想简单地将iPhone注册为AdMob上的测试设备，并拥有一个空的AdMob. initialize。
我很难理解为什么它在Android设备上工作得很好，但在iPhone上却不行。iPhone作为一个测试设备工作，不需要在AdMob.initialize中以编程方式注册，是否需要一些“额外”的东西？
我已经发现了一些帖子，建议我只需要等待几个小时的iPhone广告显示，但这已经持续了2周，所以我不认为这是一个时间/等待的事情。此外-广告工作正常，如果iPhone是编程添加如上所述，所以我不相信这是一个问题与AdMob帐户。
