IOS check Network availability ?

It's very easy in iOS ,just we need to import SystemConfiguration.framework in our project,the we need to write below few lines in class

+ (BOOL) currentNetworkStatus {

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;

BOOL connected;

BOOL isConnected;

const char *host = "www.apple.com";

SCNetworkReachabilityRef reachability = SCNetworkReachabilityCreateWithName(NULL, host);

SCNetworkReachabilityFlags flags;

connected = SCNetworkReachabilityGetFlags(reachability, &flags);

    isConnected = NO;

isConnected = connected && (flags & kSCNetworkFlagsReachable) && !(flags & kSCNetworkFlagsConnectionRequired);

CFRelease(reachability);

    if (!isConnected) {

        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:nil message:@"Network connection is unavalible.please chech your connection" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

        [alert show];

    }

return isConnected;

}

Enjoy with coding ...
