我试图弄清楚这个错误意味着什么......

我正在尝试通过 Facebook sdk 获取用户信息。我只需要他们的电子邮件和姓名

Error Domain=facebookErrDomain Code=10000 "The operation couldn’t 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
}
}

我的基本代码...（在我的 viewDidLoad 下方）

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

    [self login];

（在我的登录方法下面）

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

（和我的 Facebook 请求方法......）

- (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);
}

我真的很困惑为什么我会收到错误以及我需要更改或添加什么才能修复它......

有任何想法吗？

编辑：我的请求代码:::

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

如果您在模拟器/设备上运行应用程序尝试清理构建并全新安装应用程序。当前错误可能是由于不再有效/已撤销的访问令牌无法访问用户数据。希望能帮助到你！！！

以下是获取姓名和电子邮件的方法...我没有对其进行测试，所以如果它不起作用，请告诉我，我会找出问题所在。

如果您没有有效的访问令牌，则发送请求的方法需要进行身份验证

-(void)getUserFBInfo
{
    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"]];
    } else {
        [self apiFQLIMe];
    }
