Game Kit Bluetooth sending NSData

[jetwilson]

Hi

I am trying to develop a multiplayer game which uses the gameKit framework in OS 3.0. However I have come across some problems. Mainly sending data between devices.

I can connect two devices using the picker - that is fairly easy, however I am unsure about the whole NSData object thing I am supposed to be sending between the devices.

I want to send several vars such as NSInteger, NSString, CGPoint and CGFloats. I thought a good way to do this would be to tie these up in an array and send that, but how do I turn that into NSData and then reassemble that at the other end?

Or is there a better way?

Any light you can shed on the matter would be greatly appreciated.

Thanks

Here's how I send data:

NSMutableData *message = [[NSMutableData alloc] init];
				NSKeyedArchiver *archiver =
				[[NSKeyedArchiver alloc] initForWritingWithMutableData:message];
				[archiver encodeInt:myInt forKey:DISMISS_KEY];
				[archiver finishEncoding];
				[gkSession sendDataToAllPeers: message withDataMode:GKSendDataReliable error:NULL];
				[archiver release];
				[message release];
