Does anyone have any sample code on how to use NSSocketPort?
Here's an example from cocoadevcentral, written by H. Lally Singh:
http://www.cocoadevcentral.com/tutorials/showpage.php?show=00000038.php
// server (init the RECEIVE port as it LISTENS for connections)
NSSocketPort *port = [[NSSocketPort alloc] initWithTCPPort:1234];
NSConnection *connection = [[NSConnection alloc]
initWithReceivePort:port sendPort:nil]];
[connection setRootObject:whateverYourVending];
// client (init the SEND port as it MAKES connections)
id server;
NSSocketPort *port = [[NSSocketPort alloc] initWithTCPPort:1234
host:@"somehost" ]];
NSConnection *connection = [NSConnection
connectionWithReceivePort:nil sendPort:port];
server = [connection rootProxy];
[server setProtocolForProxy:@protocol(someprotocol)];
It doesn't compile -- I believe that initWithTCPPort:host: needs to
be initRemoteWithTCPPort:host: -- but other than that it's fine.
Related to this, I have a question which I hope somebody can answer.
Thanks to the above code my students can now send messages from the
client *to* the server. But to go in the opposite direction, do we
need to open up a second port, or can we just have the method defined
in the proxy return a value and capture that? Which is better?
Thanks,
Michael
