How can I integrate a VNC client in my app?

I need to integrate a VNC client in my app, but the only VNC open-source projects for iPhone I've found have been abandoned since 2008 and are completely out of date...

I also l开发者_Go百科ooked for free VNC viewers managing custom URL scheme, so that I can launch a third-party app for the VNC part, but again, no result.

Do you have any idea for integrating a VNC client? Even if it does not really use VNC, I only need to periodically get screenshots of a remote host (under Windows 7).

Thanks...

Here is the VNC protocol. If you are serious about making a VNC app, read this front to back 10 times. Then use your open-source code you found and you should be able to understand what is happening and why if things go wrong in the implementation.

Realizing that this question is a couple of years old... but have found a recent github project that does just this here.

Hats off to the developer Leon Liu, looks like a nice job.
