Предупреждение: This only works if the software has an application bundle; otherwise please see Show Application Title, Version, and Company
Для тех, кто хочет показать название приложения, версию и компанию для приложения в Mac OSX, это можно сделать с помощью следующего метода.
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 existence 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;
Sample output:
