Answer 1

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：

1. 确保在统一时你没有任何关于构建pods文件的可能性的消息，因为在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关于如何在OS El Capitan上做到这一点的一些提示。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统一。

2. 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，转到项目文件夹并运行命令：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”取消您的主目录。
3. Id步骤2不起作用尝试删除所有Pods文件和目录，然后添加并安装您自己的Pods，如here所示。
4. 如果仍然不起作用你只使用解决方案它使用Unity adMob sdks的旧版本，你可以下载here。和this教程手动安装谷歌广告mob sdk而不使用PodsFile。
