Question

我是iOS开发的新手，所以如果这是一个微不足道的问题，请原谅我。

我正在开发一个使用Google框架的iPhone应用程序，更具体地说，

#import <GoogleOpenSource/GoogleOpenSource.h>
#import <GooglePlus/GooglePlus.h>

我按照以下网址中的说明操作：https://developers.google.com/+/mobile/ios/getting-started。第6步指定将标记-ObjC添加到其他链接标记。如果我按照此页面上的所有说明以及位于此处的下一页https://developers.google.com/+/mobile/ios/sign-in，我可以成功从Google获取AUTH令牌以及Google+帐户中的正确电子邮件地址。

完成此操作后，我已将AWS框架添加到我的项目中，更具体地说，

#import <AWSRuntime/AWSRuntime.h>
#import <AWSRuntime/AmazonCredentials.h>
#import <AWSDynamoDB/AWSDynamoDB.h>
#import <AWSDynamoDB/DynamoDBGetItemRequest.h>

但是在编译时，我得到以下编译时错误：

Undefined symbols for architecture x86_64:
  "_NSStoreTypeKey", referenced from:
      -[AWSPersistenceDynamoDBIncrementalStore loadMetadata:] in AWSPersistence(AWSPersistenceDynamoDBIncrementalStore.o)
  "_NSStoreUUIDKey", referenced from:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

现在，如果我从其他链接标记中删除-ObjC标记，所有内容都会编译，则AWS框架可以正常工作，但点击它时，Google+按钮不执行任何操作。

我觉得我错过了一些简单的东西，比如可能只是在Google框架上使用-ObjC标志，但我找不到任何相关内容。

任何帮助将不胜感激！

Xcode其他链接器标志-ObjC
