Detect Retina Display

Question

Does iOS SDK provides an easy way to check if the currentDevice has an high-resolution display (retina) ?

The best way I've found to do it now is :

    if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)] == YES && [[UIScreen mainScreen] scale] == 2.00) {
         // RETINA DISPLAY
    }
