ios - How to check if NSNetService has stopped publishing -

-

i need find way observe when app stops publishing service via bonjour. happens when device receives call or such interruption.

background:

i'm using gcdasyncsocket communicate between 2 devices in same network app plays music (supports playback in background).

i use nsnetservice broadcast ip , port other apps (clients) connect server.

when server device receives phone call, publishing stops , other devices won't able see service.

is there particular property need observe know when has stopped , can restart again.

thanks in advance

older question, i'm facing same problem currently.

as far know can following:

you can use nsnetservicebrowser , nsnetservicebrowserdelegate delegate.

i assume you're using nsnetservicebrowser class, with

[self.domainbrowser searchforservicesoftype:@"youridentifier" indomain:@"local."];

you can set delegate on browser instance.

the delegate method - (void)netservicebrowser:(nsnetservicebrowser *)anetservicebrowser didremoveservice:(nsnetservice *)anetservice morecoming:(bool)morecoming called when nsnetservice disappeared.

you can implement method , needed operations.
