伺服器端Bonjour服務發布成功之後,用戶端可以通過NSNetService解析服務,解析成功後,可以獲得通訊的資料細節,如:IP地址、連接埠等資訊。
首先需要執行個體化NSNetService對象代碼如下:
-(id)init {_service = [[NSNetService alloc] initWithDomain:@”local.”type:@”_tonyipp._tcp.” name:@”tony”];[_service setDelegate:self];//設定解析地址逾時時[_service resolveWithTimeout:1.0];_services = [[NSMutableArray alloc] init];return self;}
執行個體化NSNetService對象的構造方法是– initWithDomain:type:name:,不需要指定它的連接埠。解析服務需要調用 [_service resolveWithTimeout:1.0]語句,開始解析服務,在規定的時間裡進行解析,參數是單位是秒。
#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:方法在解析開始時回調,解析成功時回調netServiceDidResolveAddress:方法,解析失敗時回調netService:didNotResolve:方法。
