Mix NSXPCConnection and xpc C API

Question

I am working with XPC services using NSXPCConnection wrapper, and since the Objective-C wrapper can't handle IOSurfaceRef objects, I would like to make some direct functions calls to the C API defined in xpc.h. But I can't find a way to retrieve the underlying xpc_connection_t reference (as I can see in NSXPCConnection.h, there is a private ivar called _xconnection that could be the reference I need). Am I missing something stupid, or can't the Objective-C wrapper and the C API simply be used together?

不，但是XPCKit提供了这种转换机制，并且与10.7兼容。
