Support for TLS-PSK?

[FlyingCodeMonkey]

Hi there,

Is there any way of connecting to a WSS websocket server by way of TLS-PSK instead of SSL certs?

The server I need to connect to uses PSK instead of certs and I can't figure out how to do this with SocketRocket. Apple has some sample code available ( Configuring a Wi-Fi Accessory to Join the User’s Network ) but it looks like the API they're using is only available in Swift.
