Once the
NSNetService
has been resolved, we can retrieve its addresses and
connect to it. With access to the address from the
NSNetService
, we can initialize
an
NSSocketPort
to connect to the server hosting the service. With the
NSSocketPort
initialized, we can then initialize an
NSConnection
and finally get a reference to
the
-rootProxy
of the
NSConnection
, which is actually an
NSDistantObject
proxy for
the
AppDelegate
of the server.
Once we have the
server
referenced properly, we can shut down the Bonjour
NSNetService
and start our tests.

Testing the Networking Code
Whenever I build an application that needs to communicate to a server or
another device, I always start off with simple tests to confirm that the connec-
tion is working. I generally leave these tests in place until the code goes to
production. This both provides me with a simple way to test the connectivity
and gives me a base to fall back upon if some of the higher-level functions
start to fail. For this application, let's start by setting up a group of timers
that will fire off our test methods.
-startTestTimers Implementation
To simulate a large amount of client-server traffic, this application runs sev-
eral timers at a fairly high pace. This will help us catch any race conditions
or other issues with the distributed nature of this application.
SEL selector =
@selector
(testPing);
pingTimer = [NSTimer scheduledTimerWithTimeInterval:0.5
target:self
selector:selector
userInfo:nil
repeats:YES];
selector =
@selector
(testObjectInsertion);
insertTimer = [NSTimer scheduledTimerWithTimeInterval:0.5
target:self
selector:selector
userInfo:nil
repeats:YES];
selector =
@selector
(testObjectDeletion);
