我收到 NSURLErrorDomain 错误 -1012。 xcode 6.2 中的错误，我能够成功获取访问令牌，我尝试重置模拟器.. 这是代码

-(void)getLinkedInData:(LIALinkedInHttpClient*)client
{
    [client getAuthorizationCode:^(NSString *code) {
        [client getAccessToken:code success:^(NSDictionary *accessTokenData) {
            NSLog(@"Access token data: %@",accessTokenData);
            NSString *accessToken = [accessTokenData objectForKey:@"access_token"];
               NSLog(@"Access token: %@",accessToken);
            [client GET:[NSString stringWithFormat:@"https://api.linkedin.com/v1/people/~?oauth2_access_token=%@&format=json", accessToken] parameters:nil success:^(AFHTTPRequestOperation *operation, NSDictionary *result) {
                NSLog(@"current user %@", result);
            }            failure:^(AFHTTPRequestOperation *operation, NSError *error) {
                NSLog(@"failed to fetch current user %@", error.localizedDescription);
            }];
        }                   failure:^(NSError *error) {
            NSLog(@"Quering accessToken failed %@", error);
        }];
    }                          cancel:^{
        NSLog(@"Authorization was cancelled by user");
    }                         failure:^(NSError *error) {
        NSLog(@"Authorization failed ::::%@", error.localizedDescription);
    }];
}

我不确定这是否能回答您的问题，但我发现当调用 Web 服务时同步返回 401“未授权”错误，iOS 将简单返回一个模糊的 -1012 错误。

iOS: How can i receive HTTP 401 instead of -1012 NSURLErrorUserCancelledAuthentication

因此，请尝试检查您是否遇到身份验证问题，然后从那里解决问题。
