Question

所以我一直在使用Amazon Web Services构建项目，我决定添加本地存储，所以我添加了podfile＆＃39; FMDB＆＃39; （使用此处的教学视频：https://www.youtube.com/watch?v=D5tE61gzIVs）。添加podfile后，我收到以下错误：

 Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

其中很多我甚至都没有在我的应用中使用（例如AWSGoogleSignInProvider）。我还试图改变＆＃34;其他链接标志＆＃34;通过摆脱-ObjC并添加＆＃34; -force_load（Framework途径）＆＃34;对于我正在使用的每个AWS框架。但是当我这样做时，我只得到linker command failed with exit code 1的错误。我还尝试添加在amazon sdk中找到的所有podfiles（在此处找到：https://github.com/aws/aws-sdk-ios），但仍然存在以下错误："_OBJC_CLASS_$_GIDSignIn", referenced from: objc-class-ref in AWSMobileHubHelper(AWSGoogleSignInProvider.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)。

有人知道我能为此做些什么吗？因为我确实需要利用本地存储以及我的AWS数据库，但我不确定如何解决这些错误。谢谢。

这看起来像是这里问题的重复......

请尝试以下方法...

如果您使用的是Cocoa Pods，请确保您拥有＆＃34; use_frameworks！＆＃34;您的Podfile中的行，就像这样......

platform :ios, '8.1' use_frameworks!

target 'MySampleApp' do pod 'whateverpodyouwantgoeshere' end

如果您不使用Cocoa Pod，请确保您的链接器设置与AWS Mobile Hub示例应用程序项目下载中设置的完全相同。

打开Pod文件pod-projectname.debug.xcconfig并从OTHER_LDFLAGS中删除-ObjC。这解决了这个问题。

添加与Amazon Web服务相关的podfile＆＃39; FMDB＆＃39后，应用程序无法启动
