我在团结（iOS）中使用谷歌手机广告。我在链接期间使用Xcode构建。
它显示以下错误：

主要问题是团结它无法运行/找到Cocoa pods主文件并自动安装Pods。 这就是我为解决问题所做的工作：
请确保在统一时，您没有任何关于无法构建pods文件的消息，因为Unity内部缺少pod。如果是这种情况，您需要更新/安装可可豆荚到您的mac。 Here有关如何在OS El Capitan上执行此操作的一些提示。但通常通过运行此命令你应该没问题：
sudo gem install -n / usr / local / bin cocoapods
然后关闭并重新开启团结。
打开你的Xcode文件夹，你应该有一个类似的文件：“youProjectName.xcworkspace”。如果你拥有它，打开它，如果不是那意味着当Unity尝试在你的项目中运行PodFile时出错了。尝试手动运行PodInstall，您可以通过打开命令行，转到项目文件夹并命令命令：pod install。确保Pod正确安装且没有任何错误。现在您应该看到“youProjectName.xcworkspace”取决于您的主目录。
Id步骤2不起作用尝试删除所有Pods文件和目录，然后按照指示here添加并安装您自己的Pod。
如果仍然无法解决问题，则只使用可以下载here的Unity adMob sdks的旧版本。 this教程可以在不使用PodsFile的情况下手动安装google ad mob sdk。
