iOS change statusbar style

When i set window flag MaximizeUsingFullscreenGeometryHint, Qt set prefferedStatusBarStyle of QIOSViewController to UIStatusBarStyleDefault, but i need UIStatusBarStyleLightContent.
No way to change statusbar color, when app is fullscreen. Look at the source:

    if (focusWindow->flags() & Qt::MaximizeUsingFullscreenGeometryHint)
        self.preferredStatusBarStyle = UIStatusBarStyleDefault;
    else
        self.preferredStatusBarStyle = UIStatusBarStyleLightContent;

Possible solutions:
1) using UIStatusBar key from Info.plist
2) cross-platform options to setup statusbar appearance on all platforms
