Socket disconnects in iOS5 when lock key pressed

Question

My iPhone application is based on remote desktop protocol which communcates with PC using socket programming. Everything works fine in iOS4, but now i encounter an issue with iOS5 based device.

My socket get's disconnected when user presses lock button in iOS5 based devices. I have developed a cocoa based static socket library which does all communication for my iphone app.

FYI: I just call a function exposed from my library to start the communication. I call it as a background thread using [self performSelectorInBackGround:@selector(triggerCommunication:) withObject:IP_Address];

a. Why does the socket disconnects on pressing lock button in iOS5 ? b. Is there a way to prevent the socket from not being disconnect?

Thanks,

Answer 1

If we compile with iOS5 SDK, and run application, then socket disconnects on clicking lock button.

I recompiled my application with iOS4 SDK and tested my application on iOS5 based iPhone. And now socket didnot disconnect even after locking!.
