Ios Xcode其他链接器标志-ObjC

我对iOS开发相当陌生，所以如果这是一个微不足道的问题，请原谅我

我正在开发一款使用谷歌框架的iPhone应用程序，更具体地说

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

但在编译时，我会遇到以下编译时错误：

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，如果我从其他链接器标志中删除

-ObjC

标志，所有内容都会编译，AWS框架可以工作，但单击Google+按钮时，它什么也不做

我觉得我遗漏了一些简单的东西，比如在Google框架上使用-ObjC标志，但我在这方面找不到任何东西

任何帮助都将不胜感激

看起来您需要添加核心数据框架。这很有效！谢谢您！如果你不介意我问的话，添加这个框架是如何修复这些错误的。仅供参考-如果您做出回答，我将接受。它修复了问题，因为核心数据框架提供了您报告的缺失符号。我现在明白了，谢谢。
