Check out Xamarin Reachability class here.

Answer 2

You can use Reachibility

#import "Reachability.h"
+(bool)internetConnection
 {

Reachability* reachability;
reachability = [Reachability reachabilityWithHostname:@"www.google.com"];
NetworkStatus netStatus = [reachability currentReachabilityStatus];
[reachability startNotifier];
switch (netStatus)
{
    case NotReachable:
    {
        //[self showLoadingView:@"Internet Unavailable!!"];
        [[NSNotificationCenter defaultCenter] postNotificationName:@"NetworkFail" object:self];
        return NO;
        break;
    }

    case ReachableViaWWAN:
    {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"NEtworkPass" object:self];
        return YES;
        break;
    }
    case ReachableViaWiFi:
    {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"NEtworkPass" object:self];
        return YES;
        break;
    }
}

}
