AFNetworking and No Internet Connection scenario

As of 0.9, AFHTTPClient actually has network reachability built-in (a simpler interface to Apple's aforementioned Reachability code). Just include the SystemConfiguration framework and use -setReachabilityStatusChangeBlock: to specify a response when the reachability state changes.

With AFNetworking these are the steps that one has to follow in order to take advantage of setReachabilityStatusChangeBlock: after adding the AFNetworing classes -

  1. Add SystemConfiguration.framework to your project
  2. In pch file add #import <SystemConfiguration/SystemConfiguration.h>
  3. Assuming that you have a subclass of AFHTTPClient in this subclass add below lines of code in init function -
[self setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {        NSLog(@"changed %d", status);        //your code here    }];

Maybe you could use "Reachability" to determine if the device is connected to the network.Here is the link to the Apple Doc. : Reachability

For example :

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNetworkChange:) name:kReachabilityChangedNotification object:nil];reachability = [Reachability reachabilityForInternetConnection];[reachability startNotifier];NetworkStatus remoteHostStatus = [reachability currentReachabilityStatus];if(remoteHostStatus == NotReachable) {  //Your UIAlertView}
