// 只能获取当前的SSID
- (id)fetchSSIDInfo
{
 NSString *currentSSID = @"";
 CFArrayRef myArray = CNCopySupportedInterfaces();
 if (myArray != nil){
 NSDictionary* myDict = (__bridge NSDictionary *) CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
 if (myDict!=nil){
  currentSSID=[myDict valueForKey:@"SSID"];
 } else {
  currentSSID=@"<<NONE>>";
 }
 } else {
 currentSSID=@"<<NONE>>";
 }
 
 NSArray *ifs = (__bridge id)CNCopySupportedInterfaces();
 NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
 id info = nil;
 for (NSString *ifnam in ifs) {
 info = (__bridge id)CNCopyCurrentNetworkInfo((CFStringRef)CFBridgingRetain(ifnam));
 if (info && [info count]) {
  break;
 }
 }
 
 NSLog(@"wifi info %@",info);
 
 return info;
}
wifi info {
  BSSID = "a4:2b:8c:92:47:3c";
  SSID = "XF-WORLD";
  SSIDDATA = <58462d57 4f524c44>;
}
