ios – FacebookSDK 3.0 – Apple Mach-O链接器错误

概述我正在尝试在我的一个应用程序中实现Facebook,因此遵循了Hackbook的官方Facebook教程. https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/ 我实现了所描述的一切,我没有收到任何错误或警告.但是当我尝试构建应用程序时,我会得到17个Mach-O链接器错误.

我实现了所描述的一切,我没有收到任何错误或警告.但是当我尝试构建应用程序时,我会得到17个Mach-O链接器错误.

重新实施后,清理应用程序,确保一切都在那里,我没有想法.我也在另一个应用程序中实现了它,但是再次出现了错误.来自Facebook的给定样品按照预期工作.我在互联网上做了各种各样的笔尖,但是他们都没有工作到目前为止.也许有人在这里知道一些关于API,并有一个很好的提示我:)

解决方法 我想你错过了这一行

Nsstring * const FBSessionStateChangednotification = @“FBSessionStateChangednotification”;

并添加对-lsqlite3.0的引用

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