获取Access Point的Mac地址和SSID

1.获取SSID

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

+ ( id ) fetchWifiSSIDInfo { NSArray *ifs = ( id )CNCopySupportedInterfaces(); id info = nil ; for ( NSString *ifnam in ifs) { info = ( id )CNCopyCurrentNetworkInfo((CFStringRef)ifnam); if (info && [info count]) { break ; } [info release]; } [ifs release]; return info; }

2.获取路由器的IP

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

//获取路由器的IP //ssdp协议，需要路由器开启upnp -( void ) getApIP { ssdpSock = [[AsyncUdpSocket alloc] initWithDelegate: self ]; [ssdpSock enableBroadcast:TRUE error: nil ]; NSString *str = @ "M-SEARCH * HTTP/1.1\r\nHOST: 239.255.255.250:1900\r\nMAN: \"ssdp:discover\"\r\nMX:3\r\nST: urn:schemas-upnp-org:device:InternetGatewayDevice:1\r\n\r\n" ; [ssdpSock bindToPort:0 error: nil ]; [ssdpSock joinMulticastGroup:@ "239.255.255.250" error: nil ]; [ssdpSock sendData:[str dataUsingEncoding: NSUTF8StringEncoding ] toHost:@ "239.255.255.250" port:1900 withTimeout:3 tag:1]; [ssdpSock receiveWithTimeout:-1 tag:2]; [ NSTimer scheduledTimerWithTimeInterval:3 target: self selector : @selector (completeSearch:) userInfo: self repeats: NO ]; } #pragma mark - #pragma mark AsyncUdpSocket delegate -( void ) completeSearch: ( NSTimer *)t { [ssdpSock close]; ssdpSock = nil ; [ssdpSock release]; } - ( void )onUdpSocket:(AsyncUdpSocket *)sock didNotSendDataWithTag:( long )tag dueToError:( NSError *)error { } - ( BOOL )onUdpSocket:(AsyncUdpSocket *)sock didReceiveData:( NSData *)data withTag:( long )tag fromHost:( NSString *)host port:(UInt16)port{ [[Global shareInstance] setApIP:host]; return YES ; } - ( void )onUdpSocket:(AsyncUdpSocket *)sock didNotReceiveDataWithTag:( long )tag dueToError:( NSError *)error { }
