ios - 重复符号 _OBJC_IVAR_$_GCOAuth.OAuthParameters ShareKit 和 RestKit。

Question

我处于一个棘手的情况，在过去的几天里，我无法在 sharekit 实现方面取得进展，因为我在使用 RestKit 时遇到了重复的符号错误。我正在运行 iOS 5.1 和最新版本的 xcode。根据给出的指南，我已经安装了两个库。我不明白如何从 ShareKit 或 RestKit 中删除对此的引用，而不会导致其中之一出现问题。我真的需要一些帮助...谢谢。

duplicate symbol _OBJC_IVAR_$_GCOAuth.OAuthParameters in:
    /Users/josephboston/Library/Developer/Xcode/DerivedData/Prowd_Wallet-ezxvmeygcnwgtzehshsnnprpsjww/Build/Products/Debug-iphoneos/libShareKit.a(GCOAuth.o)

您收到此错误是因为两个框架都使用通用的第三方框架。所以 Xcode 提示重复的符号。这个博客，"Avoiding duplicate symbol issues when using common utilities within a static library"正在解释解决此问题的方法。
这是那里提到的解决方案，

I’m working on two projects right now that have static libraryproducts, to be given to other developers to use in their projects:Audiobus and The Amazing Audio Engine. In both cases, I’m making quiteheavy use of my circular buffer code, TPCircularBuffer, which wouldresult in duplicate symbol errors if the static library were linkedwith another project that used it.

Use the preprocessor to rename the symbols automatically during thebuild phase.

This is done by adding a series of -DOldSymbol=NewSymbol flags to the‘Other C Flags’ build setting – like-DTPCircularBuffer=ABCircularBuffer, for instance.
