我正在尝试在我的一个应用程序中实现Facebook,因此按照Hackbook上的官方Facebook教程进行了操作。 https://developers.facebook.com/docs/howtos/login-with-facebook-using-ios-sdk/
我按照说明完成了一切,没有任何错误或警告。然而,当我尝试构建应用程序时,出现了17个Mach-O链接器错误。

重新实现后,整理应用程序,确保一切都在那里,但我已经没有更好的想法了。我还在另一个应用程序中实现了它,但是错误再次出现了。Facebook提供的示例按预期工作。我在网上试过各种提示,但到目前为止没有一个有效。也许这里有人对API了解得更多,并能给我一个好的提示 :)
