swift - Swift 和 iOS9 中的 Facebook 登录问题

Question

我一直在尝试创建一个 Tinder 克隆应用程序。现在我必须登录我的 Facebook 帐户，获取我的个人资料并显示我的显示图片。

我已经导入了最新的 FBSDK，正确配置了我的 plist ( Plist screenshot ) 并使用 graphRequest 函数来提取我的个人资料图片，但我不断收到以下错误。

-canOpenURL: failed for URL: "fbauth2:/" - error: "(null)"

我已经清理了我的构建，重新启动了我的模拟器，重新启动了我的机器并完全注释掉了我的解析代码。

我取消了所有解析代码(我通过 Heroku 部署)的注释，以免简化代码。

我在 Google 上搜索了这个问题，并在 stack Overflow 和 github 上搜索了 2 个多星期，但尚未找到解决方案。

我读过一些评论，认为由于 Facebook SDK 与 iOS 9 集成，这个问题是一个转移注意力的问题。

我想知道我做错了什么。我是编码新手，需要一些帮助。我现在想要实现的就是登录我的 Facebook 帐户(我可以做到)，授权我的应用程序(我也可以做到)并在 UiImageView 中查看我的个人资料图片(我不能做到)。这样我就可以在我的类(class)中继续构建应用程序。
