集成iOS和Google Plus SDK时的链接器错误

Question

我试图在iOS 6.1应用程序中使用Google Plus SDK进行共享，并在添加GooglePlus.framework和GoogleOpenSource.framework后出现链接器错误。

仅仅包括框架和建设产生了以下错误：在Google guide发现无济于事

Undefined symbols for architecture armv7: 
"_CGRectDivide", referenced from: 
    -[GTMOAuth2ViewControllerTouch moveWebViewFromUnderNavigationBar] in GTMOAuth2ViewControllerTouch.o 
ld: symbol(s) not found for architecture armv7 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我跟着指示。 我已经做了以下内容：

1. 包括SystemConfiguration.framework和Security.framework
2. 被拖从SDK扔下GooglePlus.framework和GoogleOpenSource.framework 到我的XCode项目
3. 添加了-ObjC标志到应用程序目标的内部设置

除了前面的步骤，我还尝试添加SDK中提供的OpenSource文件夹的内容，但那在初始修复后导致了其他问题。

我不知道我错过了，但任何帮助，将不胜感激。

Answer 1

也链接在CoreGraphics框架中。它正在寻找CGRectDivide方法，它是CoreGraphics的一部分。

Answer 2

此错误是由向您项目添加OpenSource文件夹引起的，xcode检测到存在文件重复。所以你应该只添加GooglePlus.framework和GoogleOpenSource.framework。
