Sending a custom object over NSConnection using socket ports

Hello all,

I have been experiencing some difficulties using NSConnection (using socket ports) to send a message to a vended object that takes a custom object as a parameter.

For example, if I have the following method in my vended object:

-(void)receiveMessage:(MyCustomObject*)myObject

and then I try to send a message to it, I get an NSInternalConsistencyError saying that the object cannot be unpacked.

However, if I change the method to:

-(void)receiveMessage:(NSString*)stringObject

and send an NSString, the NSString gets unpacked just fine.


Has anyone else encountered this problem?  Why does this work for Foundation objects and not my custom object?  Is there a protocol that MyCustomObject needs to implement in order for this to work?



Thanks,

Bryan Bonczek
