Setting the background color of statusbar in IOS app in XE8

Question

I want to set the background color (and foreground color) of the status bar in my freshly created Delphi XE8 Firemonkey app. With the status bar I mean the top bar with the time and wifi widgets.

I just cannot find it. I need some help :-)

Thanks, Edward

Answer 1

The Fill.Color of the form controls the color of the toolbar, and the average luminance of this color controls wether the text is white or black

Borderstyle must be <> None, or else the toolbar will be hidden.

If you have multiple forms, it is a bit unclear what form is used, but it seems like it is the last form being auto-created in your project file.

Here is some relevant sourcecode from FMX.Platform.iOS.pas that documents the color of the text:

procedure TPlatformCocoaTouch.UpdateStatusBarColor(const AForm: TCommonCustomForm);
  ...
  AppDelegate.MainWindow.RootViewController.SetStatusBarBackgroundColor((AForm as TCustomForm).Fill.Color);
  ...

procedure TFMXViewController.SetStatusBarBackgroundColor(const ABackgroundColor: TAlphaColor);
  ...
  FStatusBarLuminance := Luminance(ABackgroundColor);
  ...

function TFMXViewController.preferredStatusBarStyle: UIStatusBarStyle;
begin
  if FStatusBarLuminance < 0.5 then
    Result := UIStatusBarStyleLightContent
  else
    Result := UIStatusBarStyleDefault;
end;

PS. I have another unanswered SO question about how to make the statusbar transparent, which is native iOS 7+ behavior.
