Overview

The NSNetServiceDelegate protocol defines the optional methods implemented by delegates of NSNetService objects.Notifies the delegate that a service could not be published.Informs the delegate that an error occurred during resolution of a given service.Notifies the delegate that the TXT record for a given service has been updated.Notifies the delegate that a service was successfully published.Informs the delegate that the address for a given service was resolved.Informs the delegate that a publish or resolveWithTimeout: request was stopped.Notifies the delegate that the network is ready to publish the service.Notifies the delegate that the network is ready to resolve the service.

Instance Method Details

- (Object) netService(sender, didNotPublish:errorDict)

Notifies the delegate that a service could not be published. This method may be called long after a netServiceWillPublish: message has been delivered to the delegate.

Parameters:

  • sender (NSNetService) —

    The service that could not be published.

  • errorDict (Hash) —

    A dictionary containing information about the problem. The dictionary contains the keys NSNetServicesErrorCode and NSNetServicesErrorDomain.

Returns:

- (Object) netService(sender, didNotResolve:errorDict)

Informs the delegate that an error occurred during resolution of a given service. Clients may try to resolve again upon receiving this error. For example, a DNS rotary may yield different IP addresses on different resolution requests.

Parameters:

  • sender (NSNetService) —

    The service that did not resolve.

  • errorDict (Hash) —

    A dictionary containing information about the problem. The dictionary contains the keys NSNetServicesErrorCode and NSNetServicesErrorDomain.

Returns:

- (Object) netService(sender, didUpdateTXTRecordData:data)

Notifies the delegate that the TXT record for a given service has been updated.

Parameters:

  • sender (NSNetService) —

    The service whose TXT record was updated.

  • data (NSData) —

    The new TXT record.

Returns:

- (Object) netServiceDidPublish(sender)

Notifies the delegate that a service was successfully published.

Parameters:

Returns:

- (Object) netServiceDidResolveAddress(sender)

Informs the delegate that the address for a given service was resolved. The delegate can use the addresses method to retrieve the service’s address.

Parameters:

Returns:

- (Object) netServiceDidStop(sender)

Informs the delegate that a publish or resolveWithTimeout: request was stopped.

Parameters:

Returns:

- (Object) netServiceWillPublish(sender)

Notifies the delegate that the network is ready to publish the service. Publication of the service proceeds asynchronously and may still generate a call to the delegate’s netService:didNotPublish: method if an error occurs.

Parameters:

  • sender (NSNetService) —

    The service that is ready to publish.

Returns:

- (Object) netServiceWillResolve(sender)

Notifies the delegate that the network is ready to resolve the service. Resolution of the service proceeds asynchronously and may still generate a call to the delegate’s netService:didNotResolve: method if an error occurs.

Parameters:

  • sender (NSNetService) —

    The service that the network is ready to resolve.

Returns:
