ios - 使用 Parse 时如何获取所有 Facebook 好友的列表？

Question

以下是 getFBfriends() 在 viewDidAppear 内的代码中运行时的输出:

输出:

Result Dict: {
    data =     (
    );
    summary =     {
        "total_count" = 711;
    };
}
Found 0 friends

“total_count = 711”是正确的，但没有关于 friend 的数据。我在这里想念什么？认为权限是正确的。

代码:

class SignUpViewController: UIViewController {
@IBOutlet weak var btn_signIn: UIButton!
@IBAction func action_btnSignIn(sender: AnyObject) {

    var permissions = ["public_profile", "user_friends"]

    println("in action_btnSignIn() of SignUpViewController")


    var fbloginView:FBLoginView = FBLoginView(readPermissions: ["email", "public_profile", "user_friends"])

override func viewDidAppear(animated: Bool) {
    if PFUser.currentUser() != nil {
        println("User logged in, so launching Menu Screen")
        //self.performSegueWithIdentifier("launchmenu", sender: self)
        getDBfriends()
    } else {
        println("User NOT logged in")
    }

}
func getDBfriends() {
    var friendsRequest: FBRequest = FBRequest.requestForMyFriends()
    friendsRequest.startWithCompletionHandler{(connection:FBRequestConnection!, result:AnyObject!, error:NSError!) -> Void in
        var resultdict = result as NSDictionary
        println("Result Dict: \(resultdict)")
        var data : NSArray = resultdict.objectForKey("data") as NSArray

        for i in 0..<data.count {
            let valueDict : NSDictionary = data[i] as NSDictionary
            let id = valueDict.objectForKey("id") as String
            println("the id value is \(id)")
        }

        var friends = resultdict.objectForKey("data") as NSArray
        println("Found \(friends.count) friends")
    }
}

}

从图谱API v2.0开始，您也只能获取授权您应用的好友。结果是正确的，你的 friend 还没有授权你的应用，所以它是空的，只显示 friend 总数。
