我是 iOS 开发的新手。在我的应用程序中，我试图包含 Dropbox API。包含此 API 后，我遇到了以下错误。

在这方面做得有必要。

      -[MPOAuthCredentialConcreteStore(KeychainAdditions) addToKeychainUsingName:andValue] in DropboxSDK

感谢阿尼尔的回答。但是我已经添加了这个框架。
所有符号仅来自安全框架。可以重新检查一下框架是否正确链接
我正在添加 droupbox API，并且我正在构建而不是给出上述错误。我要删除 dropbox API，而不是删除所有错误。我不知道什么是实际问题。谢谢..
