Xcode 未定义的体系结构符号 x86_64：

Question

我已经从另一个开发人员那里接管了一个 Xcode 项目，并试图在我的本地计算机上启动和运行代码。

我收到这个错误：

Undefined symbols for architecture x86_64:

这是我来自 Xcode 的日志文件：

这是我在架构下的内容： Architectur

这是我按照 facebook SDK 入门指南导入的框架文件： Framework

Answer 1

您的项目似乎在链接时缺少依赖项，因为在链接阶段缺少 FBSDKLoginKit.framework。

尝试通过 Facebook 指南重新检查您的配置 - Getting Started with the Facebook SDK for iOS。
