如何从图形api中显示user_friends数据？

Question

I'm making an app on iOs and I allow user to log in with facebook. I already tested my app on simulator, log in using facebook with 2 account that already friend . But when I'm testing my graphpath on https://developers.facebook.com/tools/explorer/145634995501895/ . It shows nothing.

{
  "id": "1001399423222952", 
  "name": "Ega Setya Putra", 
  "friends": {
    "data": [
    ], 
    "summary": {
      "total_count": 1290
    }
  }
}

and here my code on xcode, and again it shows nil

func getDBfriends() {
    let friendsRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me?fields=id,name,friends", parameters: nil)
    friendsRequest.startWithCompletionHandler{(connection, result: AnyObject!, error) -> Void in
        if let resultdict = result as? NSDictionary{
        println("Result Dict: \(resultdict)")
        var jos = resultdict.objectForKey("data") as! NSArray
        var data : NSArray = jos

        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")
    }
    }
}

I thinks your graph path is wrong.I am using the following path in Objective-c and getting all my friends which are using the app.Let me know if this can help you.

NSData * dataFriendsList = [NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://graph.facebook.com/me/friends?access_token=%@&fields=id,first_name,picture,last_name,name,birthday,gender,location,link,hometown,email,work,education,bio",fbAccessToken]]];

And you have to take user_friends permission from Facebook.
