iOS中解析Bonjour服务(转)
服务器端Bonjour服务发布成功之后,客户端可以通过NSNetService解析服务,解析成功后,可以获得通讯的数据细节,如:IP地址、端口等信息。
首先需要实例化NSNetService对象代码如下:
- -(id)init {
- _service = [[NSNetService alloc] initWithDomain:@”local.”
- type:@”_tonyipp._tcp.” name:@”tony”];
- [_service setDelegate:self];
- //设置解析地址超时时
- [_service resolveWithTimeout:1.0];
- _services = [[NSMutableArray alloc] init];
- return self;
- }
实例化NSNetService对象的构造方法是– initWithDomain:type:name:,不需要指定它的端口。解析服务需要调用 [_service resolveWithTimeout:1.0]语句,开始解析服务,在规定的时间里进行解析,参数是单位是秒。
- #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:方法在解析开始时回调,解析成功时回调netServiceDidResolveAddress:方法,解析失败时回调netService:didNotResolve:方法。
