Delphi OSX 单元中是否有 NSLog 声明。我未能在 Firemonkey 应用程序中找到 OutputDebugString 的替代品。
最终解决方案如下所示:
/// <remarks>
/// Output debug string. Output debug string can be seen in Delphi
/// View|Debug Windows|Event Log or with 3-rd party programs such as
/// dbgview.exe from SysInternals (www.sysinternals.com)
/// </remarks>
procedure ODS(const Text: string);
begin
{$IFDEF MACOS}
// http://stackoverflow.com/questions/12405447/outputdebugstring-with-delphi-for-macosunit unt_Debug;
Log.d(Text);
{$ENDIF}
{$IFDEF LINUX}
__write(stderr, AText, Length(AText));
__write(stderr, EOL, Length(EOL));
{$ENDIF}
{$IFDEF MSWINDOWS}
OutputDebugString(PWideChar(Text));
{$ENDIF}
end;
