The linker can't find symbols related to class Facebook.
链接器找不到与类 Facebook 相关的符号。
A good first place to look would be to check whether there is a simulator (x86) build of the SDK included in your project. Usually XCode takes care of selecting the right architecture for you, but it's possible you just have the ARMv7 version.
最好首先查看项目中是否包含 SDK 的模拟器 (x86) 版本。通常 XCode 会负责为您选择正确的架构，但您可能只有 ARMv7 版本。
Care to share the command-line for the linker with us? (you can get this by selecting the log tab in the project navigator - it's the rightmost - and then drilling down to get the command-line for each build action.)
愿意与我们分享链接器的命令行吗？（您可以通过选择项目导航器中的日志选项卡来获得它——它是最右边的——然后深入获取每个构建操作的命令行。）
