Question

我有一个NSString，我想在我的墙上发布它。我阅读了文件here。我遵循这一步。在第二步，我下载sdk。在src文件夹中的src文件夹中有facebook-ios-sdk.xcodeproj文件。我打开文件并运行它。但我不知道如何导入我的项目。此外，文件夹中有示例项目，但它们不起作用。

我从here下载了FacebookSDK.framework。示例项目在sdk中工作，但是当我导入框架时，当我在框架中获取实例时，我会犯15个错误。请帮我。谢谢你。 FBLoginView * fb = [[FBLoginView alloc] init]; //我实例化了

错误是;

您应该再次关注Facebook设置指南。你还没有正确设置它，你还没有准备好使用它。你在那里的错误告诉你，你没有包含sqlite3库。

这个库是Facebook库所必需的，确保它也存在于您的项目中是您的工作。这是设置的一部分，请查看以下链接：
