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。
