NetworkExtension - NEVPNManager - objective-c

Question

Apple published with iOS 8 a new Framework "NetworkExtension".
I want to start a VPN Connection out of an app with the NEVPNManager, or has this Framework another use?
Has somebody information or an example about this Framework?
I can´t find information about it on the developer.apple.com website, only in the header files.
Thanks

The code would look something like this (exact implementation depends on the type of VPN):
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);
}
