IOS network programming-Parse bonjour service in IOS

After the Bonjour service on the server is successfully published, the client can use nsnetservice to parse the service. After successful resolution, the client can obtain the details of the communication data, such as the IP address and port.

First, you need to instantiate the nsnetservice Object Code as follows:

-(ID) Init {_ service = [[nsnetservice alloc] initwithdomain: @ "local. "Type: @" _ tonyipp. _ TCP. "Name: @" Tony "]; [_ service setdelegate: Self]; // set [_ service resolvewithtimeout: 1.0] When the resolution address times out. _ services = [[nsmutablearray alloc] init]; return self ;}

 

 

The construction method for instantiating the nsnetservice object is-initwithdomain: Type: Name:. You do not need to specify its port. The Resolution Service must call the [_ service resolvewithtimeout: 1.0] statement to start parsing the service. The parameter is in seconds.

#pragma mark - NSNetServiceDelegate Methods- (void)netServiceWillResolve:(NSNetService *)netService {NSLog(@”netServiceWillResolve”);} - (void)netServiceDidResolveAddress:(NSNetService *)netService {NSLog(@”netServiceDidResolveAddress”);[_services addObject:netService];} - (void)netService:(NSNetService *)netService didNotResolve:(NSDictionary *)errorDict {NSLog(@”didNotResolve: %@”,errorDict);}

 

Netservicewillresolve: The method is called back at the resolution start, and netservicedidresolveaddress: method when the resolution is successful. netservice: didnotresolve: method is called back when the resolution fails.
