Ios AdMob问题和错误

我正在尝试在iOS应用程序中实现AdMob。我遵循了他们提供的文档。因此，我尝试构建并运行，但出现以下错误：

编辑1:我添加了Storekit和MessageUI框架，还添加了

Obj-C

链接器标志，现在我得到了以下信息：

您是否完成了第三步：

添加所需的链接器标志 现在需要将-ObjC添加到应用程序目标的构建设置的其他链接器标志中：

在Xcode的项目导航器中，按蓝色的顶级项目图标。 单击目标，然后单击“生成设置”选项卡。 在其他链接器标志下，将-ObjC添加到Debug和Release中

他们说：

SDK库引用了六个iOS开发框架，这些框架可能 尚未成为项目的一部分：

• 储物箱
• 音频工具箱
• MessageUI
• 系统配置
• 岩芯图
• 支架
• 事件工具包
• 事件基图

您可以通过项目视图添加这些框架，如参考文档中所示。您还必须使用-ObjC链接标志

确保以与添加iOS框架相同的方式将Google LIB添加到项目中。查看。

还有AdMob 6.12.0的EventKit和EventKitUI。您是否找到了解决此问题的方法？
