NEVPNManager.saveToPreferencesWithCompletionHandler 错误

Question

我的目标平台是 OS X 10.10 / Xcode 7.2 我正在尝试保存 NEVPNManager 的首选项，但在 domain=NEConfigurationErrorDomain:

中出现错误

Error Domain = NEConfigurationErrorDomain Code = 10 "permission denied" UserInfo = 0x610000073280 {NSLocalizedDescription = permission denied}

示例代码如下：

let manager = NEVPNManager.sharedManager()
manager.loadFromPreferencesWithCompletionHandler { (error) -> Void in
    if((error) != nil) {
        print("VPN load preferences error")
        print(error!)
        exit(0)
    }
    if manager.`protocol`  == nil {
        let proto = NEVPNProtocolIKEv2()
        proto.serverAddress = "host.net"
        proto.username = "username"
        Keychain.save("vpnpassword", data: "password".dataUsingEncoding(NSUTF8StringEncoding)!)
        proto.passwordReference = Keychain.load("vpnpassword") // I got the same error without passwordReference too
        proto.authenticationMethod = NEVPNIKEAuthenticationMethod.None
        manager.`protocol` = proto
        manager.enabled = true
        manager.localizedDescription = "VPN"
        manager.saveToPreferencesWithCompletionHandler({ (error) -> Void in
            if((error) != nil) {
                print("VPN Save to Preferences error")
                print(error!)
                exit(0)
            }
            else {
                do {
                    try manager.connection.startVPNTunnel()
                    print("Started error")
                } catch {
                    print("Unexpected error")
                    }
                }
            }
        })
    }
})

我还发现了下一个日志条目：

embedded.provisionprofile 有 allow-vpn 和正确的团队 ID (T76ZSM474A)

构建的应用程序具有下一个代码签名输出

<?xml version="1.0" encoding="UTF-8"?>

我尝试反编译 Network.framework，但这并不容易。我在 OS X 10.11 上检查了这个问题，但没有发现问题，我的应用程序运行正常。我将构建的应用程序从 OS X 10.11 复制到 OS X 10.10，但出现了之前的错误。我认为文档有错误， OS X 10.10 不支持 NEVPNManager 或 OS X 10.10 上的 NEVPNManager 有错误。

我做错了什么？

Answer 1

我与 Apple 支持人员见面很久了。他们告诉我们——NEVPNManager 在 10.10 上不完全可用。您应该升级到 OS X El Capitan 或使用 Strongswan Frontend for OS X (https://wiki.strongswan.org/projects/strongswan/wiki/MacOSX).
