Using NSProxy and forwardInvocation:

Question

I would like to encode a proxy server that forwards method calls to another object via TCP without NSConnectionand NSDistanceObject. What I want is my own protocol.

The problem is that the NSProxy subclass and redefinition are forwardInvocation:not enough. I also have to overridemethodSignatureForSelector

Here is my question:

– (NSMethodSignature *)methodSignatureForSelector:(SEL)aSelector
{
    return ??? 
}

Answer 1

I found an intelligent solution for creating objects NSInvocation.
