Black blur background

[k06a]

I am trying to make this:

But I got this:

I made backgroundColor of presented view to [UIColor clearColor] in storyboard. If it is white - I see no blur at all...

Any suggestion?

Following code solves my problem:

self.useBlurForPopup = YES;
UIViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"vc_mode"];
[self presentPopupViewController:controller animated:YES completion:nil];
controller.view.layer.shadowColor = [UIColor whiteColor].CGColor;
