xib compatible with both iphone 5 and iphone 4 devices

Hi Team,

 NSString *viewName;

        if ([[UIScreen mainScreen] bounds].size.height == 568)

        {

            viewName = [[NSString alloc] initWithString:@"ViewControllerIphone5"];

            

            //this is iphone 5 xib

        }

        else

        {

            viewName=[[NSString alloc] initWithString:@"ViewController"];

           

            // this is iphone 4 xib

        }

  

  

Thanks & Regards,
