Swift 3为Facebook图形请求创建了错误 [英] Swift 3 created error for Facebook Graph Request

问题描述

我被要求更新到swift 3，现在我的facebook图表请求无法编译.它一直在给我错误类型为"Any?"的错误值.没有成员对象".它以String！)！的形式在result.object(forKey:"email")上引发此错误.在迅速解决三件事之前，它工作正常，并且从未遇到过该错误.我不确定如何解决它，因为我无法阅读所有新文档.

I was asked to update to swift 3 and now my facebook graph request won't compile. It keeps giving me the error Value of type "Any?" has no member 'object'. It throws this error on result.object(forKey: "email") as String!)!. Before swift three it worked properly and never through that error. I am not sure how to fix it as I have not been able to read through all the new documentation.

 let UserEmail = FBSDKGraphRequest.init(graphPath: "me", parameters: ["fields":"email"]).start { (connection, result, error) -> Void in


        let strEmail: String = (result.object(forKey: "email") as? String)!
    }

推荐答案

您必须将结果"转换为字典.例如:

You have to convert "result" into a dictionary. For example:

让r:[String:Any]? =结果为? [String:Any]

let r: [String: Any]? = result as? [String: Any]

...然后继续
