Getting Started with iOS network programming: Parsing Bonjour Services in iOS

Server-side Bonjour service after the successful release, the client can resolve the service through Nsnetservice, after the successful resolution, you can get the data details of the communication, such as: IP address, port and other information.

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 the resolution address timeout 
     
[_service resolvewithtimeout:1.0]; 
     
_services = [[Nsmutablearray alloc] init]; 
     
return self; 
     
}

Instantiating a Nsnetservice object is constructed by –initwithdomain:type:name: You do not need to specify its port. The parsing service needs to invoke the [_service resolvewithtimeout:1.0] statement, begin parsing the service, parse in the specified time, and the parameter is 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: Method callback at the start of parsing, callback netservicedidresolveaddress when parsing succeeds: method, callback Netservice:didnotresolve when parsing fails: method.
