    Hi All

    To check internet connection using objective c you can use this function.

    There may be a plethora of reasons that you need to check whether or not the device that is using your application has an internet connection. If checking whether the device is somehow connected to the internet is everything you want to do, Just call this function and if it is connected it will return true otherwise false


    + (BOOL)isNetworkAvailble{
        const char *host_name = "google.com";
        BOOL _isDataSourceAvailable = NO;
        Boolean success;
    
        //Creates a reachability reference to the specified
        //network host or node name.
        SCNetworkReachabilityRef reachability =
        SCNetworkReachabilityCreateWithName(NULL,host_name);
    
        //Determines if the specified network target is reachable
        //using the current network configuration.
        SCNetworkReachabilityFlags flags;
    
        success = SCNetworkReachabilityGetFlags(reachability, &flags);
        _isDataSourceAvailable = success &&
        (flags & kSCNetworkFlagsReachable) &&
        !(flags & kSCNetworkFlagsConnectionRequired);
    
        CFRelease(reachability);
        if (!_isDataSourceAvailable) {
            NSLog(@"No internet connection");
        }
        return _isDataSourceAvailable;
    }
    

    It return true i device have internet connection
