使用 Parse 时如何获取所有 Facebook 好友的列表？

Question

下面是getFBfriends()在viewDidAppear里面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"正确，但没有好友数据。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")
    }
}

}

Answer 1

您的权限是正确的，但请尝试使用另一个 fb 帐户登录您的应用程序，您将在数据响应中获得该用户的详细信息。

Answer 2

Graph v2.0后API，您也只能获取授权您App的好友。结果是正确的，none 你的朋友授权你的应用程序所以它是空的，只显示朋友总数。
