我目前正在开发一个使用地图的应用程序。所以几周前，我将Google Maps SDK v1.4.3添加到我的项目中。按照入门说明工作得很好。今天我需要将Google Analytics添加到我的项目中，所以我下载了最新的SDK（v3）。我再次按照入门说明进行操作，但现在当我尝试构建我的项目时，我收到以下错误。
你知道我该如何解决问题吗？
似乎如果我删除 -ObjC 标志，它会构建，但是当我调用 Google 地图函数时，它会崩溃并显示错误：无法识别的选择器......
所以我被困住了。我不能在同一项目中同时使用两个 SDK 吗？
谢谢大家
PS ：我的项目与iOS 5兼容。它适用于谷歌分析v2!!

我正在集成另一个库，最终遇到了同样的问题。我认为这是因为-all_load。所以对我来说，解决方案是在调试和发布 pods Pods.degug.xcconfig 和 Pods.release.xcconfig 文件中去掉这个标志。
就是这样。
我希望这对将来的某个人有所帮助。
