集成iOS和Google Plus SDK时链接器错误

Question

我正在尝试使用Google Plus SDK在iOS 6.1应用中共享，并在添加GooglePlus.framework和GoogleOpenSource.framework后出现链接器错误。

仅仅包括框架和构建产生以下错误：

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)

我按照Google guide中的说明无效。 我做了以下事情：

1. 包含SystemConfiguration.framework和Security.framework
2. 拖放GooglePlus.framework和GoogleOpenSource.framework 从SDK到我的XCode项目
3. 将-ObjC标志添加到应用目标的构建设置

除了之前的步骤，我还尝试添加SDK中提供的OpenSource文件夹的内容，但无效在初始修复后引起了其他问题。

我不确定我错过了什么，但是非常感谢任何帮助。

Answer 1

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

Answer 2

此错误是由向项目添加OpenSource文件夹引起的，xcode检测到文件重复。因此，您只应添加GooglePlus.framework和GoogleOpenSource.framework。
