要使用 Scripting Bridge，您需要根据相关应用程序的脚本定义生成头文件。 Preparing to Code Scripting Bridge 编程指南部分的开头内容如下:

Before you begin writing any Scripting Bridge code for your project, there are a few steps you should complete:

1. Generate header files for all scriptable applications that your code is sending messages to.
2. Add these files to your project.
3. In your header or implementation files, add #import statements for the generated header files.
4. Add the Scripting Bridge framework to your project.

它接着说:

To create a header file, you need to run two command-line tools—sdef and sdp—together, with the output from one piped to the other. This is the recommended syntax:

sdef /path/to/application.app | sdp -fh --basename applicationName

因此，对于使用系统事件编写脚本，您需要运行:

sdef /System/Library/CoreServices/System\ Events.app | sdp -fh --basename SystemEvents

这将生成 SystemEvents.h，其中包含 SystemEventsApplication 的定义，然后您可以将其包含在项目中。
