iPhone SDK：Bonjour和NSNetService名称！=已发布的名称？

Question

In my iPhone app, I'm publishing a bonjour service and using the following delegate method:

- (void)netServiceDidPublish:(NSNetService *)ns
{
   NSLog(@"Bonjour Service Published: http://%@.%@", [ns name], [ns domain]);
}

The "name" property is returning the device name, "How's Testing", which is correct. However, when I use Safari to discover available services the name is "hows-testing" -- the service is http://hows-testing.local.:somePortNumber .

Why is the published name different than what is being reported by the NSNetService? How do I display for the actual name of the published service? Assuming that, for some reason, there is no way to get the published name from the object, how do I determine it myself? I understand that it's based on device name, but what are the substitution rules? Remove apostrophes, replace spaces with dash...anything else? What about special characters?

Answer 1

I believe that "hows-testing" is the host name of the computer, not the name of the service. Instead, you want to look at the hostName attribute:

- (void)netServiceDidPublish:(NSNetService *)ns
{
   NSLog(@"Bonjour Service Published: http://%@", [ns hostName]);
}

You should probably also examine the port attribute, and include it in the URL, if the port is something other than the default for that protocol (80 for HTTP)
