objective-c - 网络扩展 - NEVPNManager

Question

Apple 在 iOS 8 中发布了一个新的框架“NetworkExtension”。

我想使用 NEVPNManager 从应用程序中启动 VPN 连接，或者这个框架还有其他用途吗？

有人有关于这个框架的信息或例子吗？我在 developer.apple.com 网站上找不到有关它的信息，只能在头文件中找到。

谢谢

代码看起来像这样（具体实现取决于 VPN 的类型）：

NEVPNManager *manager = [NEVPNManager sharedManager];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(vpnConnectionStatusChanged) name:NEVPNStatusDidChangeNotification object:nil];

NEVPNProtocolIPSec *protocol = [[NEVPNProtocolIPSec alloc] init];
protocol.username = @“[Your username]”;
protocol.passwordReference = [KeyChainAccess loadDataForServiceNamed:@“[Your Service Name]"];
protocol.serverAddress = @“[Your Server Address]“;
protocol.authenticationMethod = NEVPNIKEAuthenticationMethodCertificate;
protocol.localIdentifier = @“[Your Local identifier]”;
protocol.remoteIdentifier = @“[Your Remote identifier]”;
protocol.useExtendedAuthentication = NO;
protocol.identityData = [Your VPN certification private key];
protocol.disconnectOnSleep = NO;
[manager setProtocol:protocol];

[manager setOnDemandEnabled:NO];
[manager setLocalizedDescription:@"VPN"];
NSArray *array = [NSArray new];
[manager setOnDemandRules: array];
NSLog(@"Connection desciption: %@", manager.localizedDescription);
NSLog(@"VPN status:  %i", manager.connection.status);

[manager loadFromPreferencesWithCompletionHandler:^(NSError *error) {
    // do config stuff
    [manager saveToPreferencesWithCompletionHandler:^(NSError *error) {
    }];
}];


NSError *startError;
[[NEVPNManager sharedManager].connection startVPNTunnelAndReturnError:&startError];
if(startError) {
      NSLog(@"Start error: %@", startError.localizedDescription);
}
