OSX Dock Badges (Object Pascal)

Description

This example shows you how to implement notification badges for your OS X applications.

Code

unit UnMain;
 
interface
 
uses
 
//These frameworks define types that map to the Mac OS X Objective-C based 'Cocoa' API.
  Macapi.AppKit, //You need it to create an '''NSApplication''' instance.
  Macapi.Helpers, //You need it to use the function StrToNSStr(). 
 
 
  System.SysUtils, System.Types, System.UITypes, System.Classes, System.Variants, 
  FMX.Types, FMX.Graphics, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.StdCtrls;
 
type
  TFrmBadgeLabel = class(TForm)
    BadgeLabel: TButton;
    procedure BadgeLabelClick(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;
 
var
  FrmBadgeLabel: TFrmBadgeLabel;
 
implementation
 
{$R *.fmx}
 
procedure TFrmBadgeLabel.BadgeLabelClick(Sender: TObject);
var
// Create an instance of NSApplication
  NSApp: NSApplication;
begin
  NSApp := TNSApplication.Wrap(TNSApplication.OCClass.sharedApplication);
  NSApp.dockTile.setBadgeLabel(StrToNSStr('23'));
end;
 
end.

You will see the badge on the icon's app after clicking the button.
