  另一种方式，

  - (BOOL)isReachable {
  return [self isReachableViaWWAN] || [self isReachableViaWiFi];
  }
  
  - (BOOL)isReachableViaWWAN {// If this return true, means it is connected to 3g
  return self.networkReachabilityStatus == 
  AFNetworkReachabilityStatusReachableViaWWAN;
  }
  
  - (BOOL)isReachableViaWiFi { // If this return true, means it is connected to wifi
  return self.networkReachabilityStatus == 
  AFNetworkReachabilityStatusReachableViaWiFi;
  }
  

  确保正确初始化类并执行

  [self.manager.reachabilityManager startMonitoring];

  请先看Reachibility

  导入类后写入.h

  Reachability* reachability;
  

  .m级

  [[NSNotificationCenter defaultCenter] addObserver:self 
   selector:@selector(handleNetworkChange:) name:kReachabilityChangedNotification object:nil]; 
    reachability = [Reachability reachabilityForInternetConnection]; 
   [reachability startNotifier]; 
   NetworkStatus remoteHostStatus = [reachability currentReachabilityStatus]; 
   if(remoteHostStatus == NotReachable) 
   {
  NSLog(@"no");
   } 
   else if (remoteHostStatus == ReachableViaWiFiNetwork) 
   {
  NSLog(@"wifi"); 
  } 
  else if (remoteHostStatus == ReachableViaCarrierDataNetwork) 
  {
  NSLog(@"cell"); 
  } 
  ..... 
  
   - (void) handleNetworkChange:(NSNotification *)notice 
   {   
  NetworkStatus remoteHostStatus = [reachability currentReachabilityStatus];   
  if(remoteHostStatus == NotReachable) 
  {
      NSLog(@"no");
  }   
  else if (remoteHostStatus == ReachableViaWiFiNetwork) 
  {
      NSLog(@"wifi"); 
  }   
  else if (remoteHostStatus == ReachableViaCarrierDataNetwork) 
  {
      NSLog(@"cell"); 
  } 
  }
