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:

[cpp]
-(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; 
 

-(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。

[cpp]
#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); 
 

#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。
