Transparent ViewController to See Parent Below?

Question

I would like to modally add a view controller with a transparent background, so the parent view controller beneath can be seen. (This is in an app for iPhone, not for iPad.)

Answer 1

UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
    ChooseController *sec=[story instantiateViewControllerWithIdentifier:@"Controller"];
    sec.modalPresentationStyle = UIModalPresentationOverCurrentContext;
    sec.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
    [self presentViewController:sec animated:YES completion:^{

    }];

Note:Present controller superview alpha value must be below 1 like 0.5 alpha like that.
