Share Extension Status bar style

Question

When creating a fullscreen share extension, is there a way to control the status bar?

I tried:

• view controller based status bar + preferredStatusBarStyle
• status bar style
• status bar is initially hidden

Nothing seems to affect the status bar, it is just inherited from the view that opened the share extension. Is there a workaround or is that by design how it must work?

Answer 1

There's currently no way to change the status bar style for an extension view (http://openradar.appspot.com/radar?id=6397505050771456). It seems like the status bar for the extension uses the same style as the app that called the extension.

You can actually change it if you swizzle the preferredStatusBarStyle method on the parent view controller. Since you can do that without using any non-public APIs, that * should * be app-store safe.

static UIStatusBarStyle statusBarStyle;

static UIStatusBarStyle preferredStatusBarStyle(id self, SEL _cmd)
{
  return statusBarStyle;
}

void setPreferredStatusBarStyleOnRootVC(UIStatusBarStyle style, UIViewController *vc)
{
  statusBarStyle = style;
  static BOOL swizzeld = NO;
  if(swizzeld)
  {
    [vc setNeedsStatusBarAppearanceUpdate];
    return;
  }

  swizzeld = YES;

  UIViewController *parent;
  while((parent = vc.parentViewController))
    vc = parent;

  class_addMethod(vc.class, @selector(preferredStatusBarStyle), (IMP)&preferredStatusBarStyle, "v@:");
}
