How to check whether there is internet connection with the device: cocos-2d

In one of my iPhone app, I need to find out whether there is internet connection with the device or not. Anyone pls help?

How do you check if there is an Internet connection?

Select the Start button, then type settings. Select Settings > Network & internet. The status of your network connection will appear at the top. Windows 10 lets you quickly check your network connection status.

Use Reachability class.

  if([self checkInternetConnected] ) 
  {
    NSLog(@"Internet connected\n");
  } 


- (BOOL)checkInternetConnected 
{
    Reachability *reachability = [Reachability reachabilityForInternetConnection];  
    NetworkStatus networkStatus = [reachability currentReachabilityStatus]; 
    return !(networkStatus == NotReachable);
}

You can get rechability class here : Download sample and add Reachability.h and Reachability.m into your project.
