iOS網路編程-iOS中解析Bonjour服務

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：

[cpp]
-(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; 
 
} 

-(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。

[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。
