Your classes are missing from Build target. I don't know about your project structure and files but it looks like GADBannerView and GADRequest classes are missing.
Build 目标中缺少您的类。我不知道您的项目结构和文件，但看起来缺少 GADBannerView 和 GADRequest 类。
Remove these files from your project. add them again and remember to check "ADD TO TARGET" checkbox.
从您的项目中删除这些文件。再次添加它们并记住选中“添加到目标”复选框。

this error shows that u haven't added GADBannerView, and GADRequest classes.
此错误表明您尚未添加 GADBannerView 和 GADRequest 类。
please check by following this steps:
请按照以下步骤检查：
in XCode select your Project in the Target Section then switch to BuildPhases->CompileSources
在 XCode 的目标部分中选择您的项目，然后切换到 BuildPhases->CompileSources
here check for GADBannerView.m and GADRequest.m files.
在这里检查 GADBannerView.m 和 GADRequest.m 文件。
XCode->Your Project in Target section->BuildPhases->CompileSources
XCode->您在目标部分中的项目->BuildPhases->CompileSources
hope this will help you.
希望这会帮助你。
