FacebookSDK 3.0 - Apple Mach-O Linker Error
提问by Blade
I am trying to implement Facebook in one of my apps and therefore followed the official Facebook Tutorial on Hackbook. https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/
我正在尝试在我的一个应用程序中实施 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/
I implemented everything as described and I don't get any error or warnings. However when I try to build the app, I get 17 Mach-O Linker Errors.
我按照描述实施了所有内容，但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。

ld: symbol(s) not found for architecture i386
After reimplementing, cleaning the app, making sure everything was there, I am out of ideas. I also implemented it in another app, but good the errors again. The given samples from Facebook however work as intended. I did various tipps on the internet, but none of them worked so far. Maybe someone here knows something about the API and has a good tip for me :)
重新实现，清理应用程序，确保一切都在那里后，我没有想法。我也在另一个应用程序中实现了它，但再次解决了错误。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，并为我提供了一个很好的提示:)

I think you are missing this line
我想你错过了这一行
NSString *const FBSessionStateChangedNotification = @"FBSessionStateChangedNotification";
NSString *const FBSessionStateChangedNotification = @"FBSessionStateChangedNotification";
and adding reference to -lsqlite3.0
并添加对 -lsqlite3.0 的引用

Yes, I found the Solution : libsqlite3.dylibthat i used compiled for armv6 not 7 , so you download Xcode dmg file (more then 4.2)and extract the lib from it .
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，因此您下载 Xcode dmg 文件（超过 4.2）并从中提取 lib。
