Here again, you need to retain connection if it's an ivar. Also,
you need to run the call to -rootProxy inside an exception
handler, and catch any exceptions raised (timeouts are common).
Your NSLog of proxy will likely crash since you didn't initialize
the local variable to nil, as well. Having netService as an ivar
assigned here doesn't make sense, either.
The method now looks like this:
And do you catch an exception when you send [connection rootProxy]?
[...]
Thanks for the example! I've been comparing your code to mine and
they're almost identical. The only thing that's different is that
you use NSPort's instead of NSSocketPorts for the server and that
you establish (in the D-O setup) a NSConnection (using +
[NSConnection connectionWithReceivePort: sendPort]) both a sending
and receiving port, while I only use a receiving port. Would this
be causing a problem as the server cannot send replies?
We use NSPorts for communication between threads. An NSSocketPort is
used for communication between hosts (BDSKSharingServer <->
BDSKSharedGroupServer).
Finally, would it matter if I'm running the server and the client
on the same machine (localhost) over the network? I don't think it
should, but I'm wondering if it could be causing any problems.
Because I did notice that when, in the client, I did: NSLog
(@"service: %@", [netService hostName]); the value was (null).
If you were able to publish the service successfully, your client
probably hasn't resolved the service yet with -[NSNetService
resolveWithTimeout:]. You'll have to do that first, and then wait
for the delegate method to be called.
Also, check your firewall settings, and you might want to start with
something simple, like modifying the PictureSharing sample code to
use DO over Bonjour, just to make sure it works on your machine.
