获取WIFI的相关信息
1 - (void)getWifiInfo 2 { 3 NSArray *ifs = (__bridge_transfer NSArray *)CNCopySupportedInterfaces(); 4 if (!ifs) { 5 return ; 6 } 7 NSDictionary *info = nil; 8 for (NSString *ifnam in ifs) { 9 info = (__bridge_transfer NSDictionary *)CNCopyCurrentNetworkInfo((__bridge CFStringRef)ifnam); 10 if (info && [info count]) { 11 break; 12 } 13 } 14 NSLog(@"WIFI名称 %@ MAC地址 %@",info[@"SSID"],info[@"BSSID"]); 15 }
获取WIFI网关以及子网掩码，端口等信息
