iOS以快速，最新的FBSDK为用户的家乡 [英] iOS get user's hometown with swift and latest FBSDK

问题描述

我找不到适用于Facebook SDK的快速文档。我正在使用最新版本，我设法检索用户的姓名，年龄，邮件和个人资料图片。我不知道如何找到家乡。

I couldn't find a swift doc for Facebook SDK. I'm using the latest version and I managed to retrieve name, age, mail and profile picture of the user. I can't find out how to find the hometown though.

当我尝试这个：

conn.addRequest(req, completionHandler:  { (connection: FBSDKGraphRequestConnection!, result: AnyObject!, error: NSError!) -> Void in
            if(error != nil){
                println(error)
            } else {
                let loc = result.objectForKey("hometown") // loc is nil

            }
        })
        conn.start()

我发现没有。我知道.objectForKey（hometown）应该返回一个Page而不是一个String，但是我不知道如何处理页面。

I found nil. I know that ".objectForKey("hometown")" should return a "Page" and not a "String" but I don't know how to handle a page.

Cheers

我需要添加 user_location 在登录权限然后，找到位置，我使用：

EDIT : (thanks to Tobi) I needed to add the user_location in login permissions and then, to find the location, I used :

let obj = result.objectForKey("location")
let location = obj.objectForKey("name") as! String

推荐答案

您需要确保用户访问令牌您正在使用的包含 user_hometown 权限：

You need to make sure that the User Access Token you're using contains the user_hometown permission:

• https://developers.facebook.com/docs/facebook-login/permissions#reference-user_hometown

• https://developers.facebook.com/docs/facebook-login/permissions#reference-user_hometown

另外，请确保您真的想要 hometown 而不是用户的位置（当前城市）。后者将是 user_location 权限：

Also, make sure that you really want the hometown and not the location (current city) of the user. The latter would be the user_location permission:
