iphone - iPhoneFacebookSDKエラー

Question

このエラーの意味を理解しようとしています...

FacebookSDKを介してユーザー情報を取得しようとしています。必要なのは彼らのメールアドレスと名前だけです

Error Domain=facebookErrDomain Code=10000 "The operation couldn‚Äôt be completed. (facebookErrDomain error 10000.)" UserInfo=0xde94ad0 {error=<CFBasicHash 0xde7d100 [0x3f616650]>{type = mutable dict, count = 3,
entries =>
    2 : <CFString 0xde722a0 [0x3f616650]>{contents = "type"} = <CFString 0xdeba1a0 [0x3f616650]>{contents = "OAuthException"}
    3 : <CFString 0xde6ba20 [0x3f616650]>{contents = "message"} = <CFString 0xdeb12a0 [0x3f616650]>{contents = "An active access token must be used to query information about the current user."}
    6 : <CFString 0xde74c40 [0x3f616650]>{contents = "code"} = 2500
}
}

私の基本的なコード...（以下のviewDidLoadで）

facebook = [[Facebook alloc] initWithAppId:@"random#123456" andDelegate:self];

    [self login];

（以下の私のログイン方法で）

- (void) login {
    NSArray *permissionsArray = [NSArray arrayWithObjects:@"email", nil];
    [facebook authorize:permissionsArray];
}

（そして私のFacebookリクエストメソッド...）

- (void)request:(FBRequest *)request didLoad:(id)result {
    NSLog(@"Inside didLoad");
    if ([result isKindOfClass:[NSArray class]]) {
        result = [result objectAtIndex:0];
    }
    // When we ask for user infor this will happen.
    if ([result isKindOfClass:[NSDictionary class]]){
        //NSDictionary *hash = result;
        NSLog(@"Name: %@", [result objectForKey:@"name"]); 
    }
    if ([result isKindOfClass:[NSData class]])
    {
        NSLog(@"Profile Picture");
        //[profilePicture release];
        //profilePicture = [[UIImage alloc] initWithData: result];
    }
    NSLog(@"request returns %@",result);
    //if ([result objectForKey:@"owner"]) {}

};

- (void)request:(FBRequest *)request didFailWithError:(NSError *)error{ 
    NSLog(@"%@",error);
}

エラーが発生する理由と、それを修正するために何を変更または追加する必要があるのか、本当に混乱しています...

何か案は？

編集：私のリクエストコード:::

- (IBAction)requestFBFriends:(id)sender {
    NSLog(@"HERE");
    [facebook requestWithGraphPath:@"me/friends" andDelegate:self];
}

シミュレーター/デバイスでアプリケーションを実行している場合ビルドをクリーンアップして、アプリケーションをフレッシュインストールしてみてください。現在のエラーは、ユーザーデータへのアクセスに無効になった非アクティブ/失効したアクセストークンが原因である可能性があります。それが役に立てば幸い！！！

名前とメールアドレスを取得する方法は次のとおりです...私はテストしなかったので、うまくいかない場合は、教えてください。問題を見つけます。

有効なアクセストークンがない場合、リクエストを送信するメソッドは認証する必要があります

{
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {
        self.facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        self.facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }
    if (![self.facebook isSessionValid]) {
        NSLog(@"auth");
        [self.facebook authorize:[NSArray arrayWithObject:@"email"]];
