Cocoa - NSNetserviceErrorCode = -72003

Question

Hiyee...Now I'm having this 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

Answer 1

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.)

Answer 2

hmmm...I have check the description of the error code... [The net service is busy and cannot process the request]... but now I'm having difficulties in solving...help help Thankz for the reply anyway

Answer 3

Hmmm...I shall explain more...I'm trying to do a cocoa application that have two-way communication. My UI contain one textview which is use for display the available domains and another textview for displaying the sended text. There is 3 buttons, Search(search for domain), Connect(to connect on the selected domain) & Send( to send text message to the domain user). Now I'm stuck after I select the domain and it display this error " NSNetServicesErrorCode = -72003; NSNetServicesErrorDomain = 10; "
Below is my full code... Please help to see for any mistake, thanks!
