在iOS中使用NEVPNManager连接到vpn时出错

Question

我正在尝试使用NEVPNManager以编程方式配置vpn并且我成功保存首选项，但是当我尝试连接时，我收到错误“与VPN服务器的协商失败”。在protocolConfiguration中有什么特别的东西可以使它工作吗？

提前致谢。

确保正在正确设置VPN配置。 这是示例代码。

NEVPNProtocolIPSec * protocalConfigurationIPSec = [[NEVPNProtocolIPSec alloc] init];            protocalConfigurationIPSec.username = @＆＃34; account＆＃34 ;;

        protocalConfigurationIPSec.passwordReference = passwordReference;
        protocalConfigurationIPSec.serverAddress = @"ipaddress";
        protocalConfigurationIPSec.authenticationMethod = NEVPNIKEAuthenticationMethodSharedSecret;
        protocalConfigurationIPSec.sharedSecretReference = sharedSecretReference;
        protocalConfigurationIPSec.localIdentifier = @"userGroup"];
        protocalConfigurationIPSec.remoteIdentifier = [serverDict objectForKey:@"userGroup";
        **protocalConfigurationIPSec.useExtendedAuthentication = YES;**
        protocalConfigurationIPSec.disconnectOnSleep = NO;
        manager.protocolConfiguration=protocalConfigurationIPSec;
        [manager setOnDemandEnabled:NO];
        [manager setLocalizedDescription:@"VPN"];
        manager.enabled = true;
