如何在使用Parse时获取所有Facebook好友列表？

问题描述

以下是在 viewDidAppear 中的代码中运行 getFBfriends（）时的输出：

Following is the output when getFBfriends() is run in the code inside viewDidAppear below:

输出：

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

total_count = 711是正确但是没有关于朋友的数据。我在这里错过了什么？认为权限是正确的。

The "total_count = 711" is correct but there is not data about the friends. What I am I missing here? Think the permissions are correct.

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")
    }
}

}

推荐答案

您的权限是正确的，但尝试使用其他fb帐户登录您的应用，您将在数据响应中获得该用户详细信息。

Your permissions are correct, but try to login your app using another fb account you will get that user details in your data response.
