swift - facebook 自定义按钮 xcode 8 (swift 3)，操作不起作用

Question

我什至从 facebook 开发者页面尝试简单的代码，fb 按钮将我重定向到应用程序确认(页面显示:已确认)- 而不是 facebook 登录页面。如果我(safari)在 FB 上登录，没有任何变化......

这是代码:

    func loginButtonClicked() {
    var login = FBSDKLoginManager()
 //   login.logInWithReadPermissions(["public_profile"], fromViewController: self, handler:{(result: FBSDKLoginManagerLoginResult?, error: NSError?) -> Void in
       login.logInWithReadPermissions(["public_profile"], fromViewController: self, handler:{(result:FBSDKLoginManagerLoginResult? , error: NSError?) -> Void in
        if error {
            print("Process error")
        }
        else if result.isCancelled() {
            print("Cancelled")
        }
        else {
            print("Logged in")
        }            
    })
}

错误日志:

试试这个

       func loginButtonClicked() {
        var login = FBSDKLoginManager()
        login.logIn(withReadPermissions:["public_profile"], fromViewController: self, handler:{ response ,error in
        if error {
          print("Process error")
        }
        else if result.isCancelled() {
          print("Cancelled")
        }
        else {
          print("Logged in")
        }            
     })}
