presentViewController black background instead of transparent

Question

I have a view that I wish to present to the user in the standard way (sliding up from the bottom of the screen). About half this view is a transparent background and the bot

Answer 1

I had a similar problem with the black background appearing after a short delay when creating the controller with

    Disclaimer *vc = [[Disclaimer alloc]init];

What solved the problem for me was to create a corresponding object in IB and instantiate the viewcontroller using it's storyboard ID:

     Disclaimer *vc = (Disclaimer *)[self.storyboard instantiateViewControllerWithIdentifier:@"SBIDDisclaimer"];
[self presentViewController:vc animated:YES completion:nil];

I guess doing it via IB does some additional initialisations.
