鏈接器命令失敗，退出代碼1，XCode 4.5，Facebook SDK 3.1

Question

我正在嘗試將Facebook SDK集成到我的xcode項目中，並且我遇到了一個絆腳石。

經過一番研究，我試着確保我有最新版本的FacebookSDK，因爲那些有同樣的錯誤，因爲我能夠解決他們與最新版本的問題，但沒有幫助，所以我嘗試了從github下載源代碼並使用build_all.sh命令重新編譯，這也沒有幫助。

我要完整的錯誤日誌是在年底，因爲它是超長的，但這裏是在結尾部分：

clang: error: linker command failed with exit code 1 (use -v to see invocation)

我見過很多字符串相關的這個問題，但如我之前說過，既不更新到最新的SDK（我已經擁有了這個不必要的步驟）或重新編譯armv7的源代碼，armv7s解決了這個問題。

由於提前，
