我正在尝试在我的一个应用程序中实现 Facebook，因此遵循了 Hackbook 上的官方 Facebook 教程。https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/

我按照描述实现了所有内容，没有收到任何错误或警告。但是，当我尝试构建应用程序时，我收到 17 个 Mach-O 链接器错误。

在重新实现，清理应用程序，确保一切都在那里之后，我没有想法了。我也在另一个应用程序中实现了它，但又出现了错误。然而，来自 Facebook 的给定样本按预期工作。我在互联网上做了各种提示，但到目前为止都没有奏效。也许这里有人对 API 有所了解，并且对我有一个很好的提示 :)

我想你错过了这条线

NSString *const FBSessionStateChangedNotification = @"FBSessionStateChangedNotification";

并添加对 -lsqlite3.0 的引用

请参阅https://developers.facebook.com/docs/getting-started/getting-started-with-the-ios-sdk/#project

我想你错过了这个

转到项目->构建阶段->链接二进制-添加->-lsqlite3.0

是的，我找到了解决方案：libsqlite3.dylib我使用的是为 armv6 而不是 7 编译的，所以你下载 Xcode dmg 文件（超过 4.2）并从中提取 lib。
