Best way to check connectivity using AFNetworking 2 in iOS?

I want to check if user device is connected to internet or not before make a request to server. For this i'm doing this in AppDelegate class

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
    [self connectivity];
}
    -(void)connectivity
    {
        [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status){

        }];

        // Set the reachabilityManager to actively wait for these events
        [[AFNetworkReachabilityManager sharedManager] startMonitoring];
    }

and when i make any request i do 

AFNetworkReachabilityStatus status = [AFNetworkReachabilityManager sharedManager].networkReachabilityStatus;
BOOL con = (status == AFNetworkReachabilityStatusReachableViaWiFi || status == AFNetworkReachabilityStatusReachableViaWWAN);
//BOOL con =[AFNetworkReachabilityManager sharedManager].reachable;//give same result as networkReachabilityStatus

But first time when i make request it gives me NO and after some time it gives correct value. Please suggest the best way to monitor connectivity.

You can check property networkReachabilityStatus:

AFNetworkReachabilityStatus status = [AFNetworkReachabilityManager sharedManager].networkReachabilityStatus;
BOOL rechable = (status == AFNetworkReachabilityStatusReachableViaWiFi || status == AFNetworkReachabilityStatusReachableViaWWAN);

If you want to try do smth while the status is AFNetworkReachabilityStatusUnknown, you can use: 

BOOL rechable = (status == AFNetworkReachabilityStatusReachableViaWiFi || status == AFNetworkReachabilityStatusReachableViaWWAN || status == AFNetworkReachabilityStatusUnknown);

P.S.

Checking of the reachability is asynchronous operation, see SCNetworkReachabilityRef, therefore you can't get networkReachabilityStatus in the applicationDidFinishLaunching method.
