Cocoa - NSNetserviceErrorCode = -72003

Hiyee...Now I'm having this开发者_如何学JAVA error " NSNetServicesErrorCode = -72003; NSNetServicesErrorDomain = 10; " when I was trying to connect to a domain.

My Code for connection:

-(IBAction)connect:(id)sender {
    NSNetService *remoteService = servicesController.selectedObjects.lastObject;
    remoteService.delegate = self;
    [remoteService resolveWithTimeout:30];
}

Error Code:

-(void)netService:(NSNetService *)service didNotResolve:(NSDictionary *)errorDict {
    NSLog(@"Could not resolve: %@", errorDict);
}

Thankz

This is documented in the documentation for the underlying CFNetwork library. (If you look a little bit up the page, you'll see that that name has the value you found in your error dictionary.)
