Mac Show Application Title, Version, and Company

This article applies to Mac OS X only.

Also see Show Application Title, Version, and Company.

For those who want to show the Application Title, Version, and Company for an application on Mac OSX, this can be done using the following method.

This only works if the application has an application bundle; otherwise please see Show Application Title, Version, and Company#Mac OS X and iOS.

Beware! CFBundleGetMainBundle does not really return nil if application has no bundle.

Instead it tries to create that handle. See Apple's documentation. So we should check ValueRef existance too.

// CODE FOR SHOWING APPLICATION TITLE, VERSION, AND COMPANY
uses MacOSAll, CarbonProc, StrUtils;

var
  BundleID: String;
  BundleName: String;
  BundleRef: CFBundleRef;
  BundleVer: String;
  CompanyName: String;
  KeyRef: CFStringRef;
  ValueRef: CFTypeRef;

function GetInfoPlistString(const KeyName : string) : string;
begin
  try
    Result := '';
    BundleRef := CFBundleGetMainBundle;
    if BundleRef = nil then Exit;  {Executable not in an app bundle?}
    KeyRef := CFStringCreateWithPascalString(nil,KeyName,kCFStringEncodingUTF8);
    ValueRef := CFBundleGetValueForInfoDictionaryKey(BundleRef, KeyRef);
    if ValueRef = nil then Exit;  {Executable not in an app bundle!}
    if CFGetTypeID(ValueRef) <> CFStringGetTypeID then Exit;  {Value not a string?}
    Result := CFStringToStr(ValueRef);
  except
  on E : Exception do
    ShowMessage(E.Message);
  end;
  FreeCFString(KeyRef);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
   try
     Form1.Caption := 'About '+Application.Title;
     StaticTextAppTitle.Caption := Application.Title;
     BundleID := GetInfoPlistString('CFBundleIdentifier');
     '''// CompanyName is presumed to be in the form of: com.Company.AppName'''
     CompanyName := AnsiMidStr(BundleID,AnsiPos('.',BundleID)+1,Length(BundleID));
     CompanyName := AnsiMidStr(CompanyName,0,AnsiPos('.',CompanyName)-1);
     BundleVer := GetInfoPlistString('CFBundleVersion');
     StaticTextAppVer.Caption := Application.Title+' version '+BundleVer;
     StaticTextCompany.Caption := CompanyName;
   except
   on E : Exception do
          ShowMessage(E.Message);
   end;
end;
