I have tried everything suggested here: Status bar won't disappear to no avail.

Have you already, on your info.plist file, added two new attributes if not present? Please try setting "Status bar is initially hidden" to "YES" and also set "UIViewControllerBasedStatusBarAppearance" to "NO". This will hide status bar for your app.
YES
UIViewControllerBasedStatusBarAppearance
NO
