iOS网络编程-iOS中解析Bonjour服务

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。
