iOS facebookSDK 获取用户详细信息

Question

我正在使用最后一个 FBSDK(使用 swift)

// MARK: sign in with facebook

func signInWithFacebook()
{
    if (FBSDKAccessToken.currentAccessToken() != nil)
    {
        // User is already logged in, do work such as go to next view controller.
        println("already logged in ")
        self.returnUserData()

        return
    }
    var faceBookLoginManger = FBSDKLoginManager()
    faceBookLoginManger.logInWithReadPermissions(["public_profile", "email", "user_friends"], handler: { (result, error)-> Void in
        //result is FBSDKLoginManagerLoginResult
        if (error != nil)
        {
            println("error is \(error)")
        }
        if (result.isCancelled)
        {
            //handle cancelations
        }
        if result.grantedPermissions.contains("email")
        {
            self.returnUserData()
        }
    })
}

func returnUserData()
{
    let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: nil)
    graphRequest.startWithCompletionHandler({ (connection, result, error) -> Void in

        if ((error) != nil)
        {
            // Process error
            println("Error: \(error)")
        }
        else
        {
            println("the access token is \(FBSDKAccessToken.currentAccessToken().tokenString)")

            var accessToken = FBSDKAccessToken.currentAccessToken().tokenString

            var userID = result.valueForKey("id") as! NSString
            var facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"



            println("fetched user: \(result)")


}

当我打印获取的用户时，我只得到 ID 和名称! ,但我请求了电子邮件、 friend 和个人资料的许可，怎么了？？？

顺便说一句:我把这个项目从我的 macbook 移到了另一个 macbook(因为我格式化了我的)它在我创建项目的 macbook 上工作得很好，但是在移动项目之后(使用 bitbucket clone)我得到了这个结果。

根据新的 Facebook SDK，您必须使用 FBSDKGraphRequest 传递参数

if((FBSDKAccessToken.currentAccessToken()) != nil){
    FBSDKGraphRequest(graphPath: "me", parameters: ["fields": "id, name, first_name, last_name, email"]).startWithCompletionHandler({ (connection, result, error) -> Void in
        if (error == nil){
            println(result)
        }
    })
}

用户对象引用:https://developers.facebook.com/docs/graph-api/reference/user

通过公开个人资料，您可以获得性别:

public_profile (Default)

Provides access to a subset of items that are part of a person's public profile. A person's public profile refers to the following properties on the user object by default:

id
name
first_name
last_name
age_range
link
gender
locale
timezone
updated_time
