AFNetworking 2.0 Reachability alert always showing - ios

Question

I am using AFNetworking 2.0 to make network calls. I am using the code below for reachability. My problem is that the "Not connected" alert always shows when I open the app. It seems like it takes a while for the app to get connected to the network and that lag is causing the alert to pop up. Is there any way to fix this? I don't want the "Not connected" alert popping up every time and confusing users.
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
NSLog(#"Reachability: %#", AFStringFromNetworkReachabilityStatus(status));
switch (status) {
{case AFNetworkReachabilityStatusNotReachable:
NSLog(#"No Internet Connection");
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Not connected"
message:#"You have no network connection"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
}
break;
{case AFNetworkReachabilityStatusReachableViaWiFi:
NSLog(#"WIFI");
}
break;
{case AFNetworkReachabilityStatusReachableViaWWAN:
NSLog(#"4G");
}
break;
default:
NSLog(#"Unkown network status");
break;
}
}];
[[AFNetworkReachabilityManager sharedManager]startMonitoring];
if ([[AFNetworkReachabilityManager sharedManager] isReachable] == NO) {
UIAlertView *message = [[UIAlertView alloc] initWithTitle:#"Not connected"
message:#"You're not connected to the internet. Please connect via WiFi or data plan"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[message show];
//this shows all the time - why?
}

Answer 1

put this code in your AppDelegate in this method didFinishLaunchingWithOptions. it will display message only one time.
internetReachableFoo = [Reachability reachabilityWithHostname:#"www.google.com"];
internetReachableFoo.reachableBlock = ^(Reachability*reach)
{
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(#"Yayyy, we have the interwebs!");
});
};
internetReachableFoo.unreachableBlock = ^(Reachability*reach)
{
dispatch_async(dispatch_get_main_queue(), ^{
UIAlertView *alrt=[[UIAlertView alloc]initWithTitle:#"Error" message:#"No Internet Connection\nPlease Check The Connection" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alrt show];
});
};
[internetReachableFoo startNotifier];

Answer 2

Because AFNetworkReachabilityManager refreshs its status by notification.
So when you call
[AFNetworkReachabilityManager sharedManager] isReachable]
after the startMonitoring immediately,the status is not get ready.
