Cocoa：在第三方应用程序中获取和更改文本和选择（不模拟按键或使用辅助功能 API）

Question

I'm writing a Mac utility app in which I would like to manipulate text and selection in third-party apps. I found two methods for doing so:

• Simulating key presses
• Using the accessibility API

However, they both have major drawbacks and I'm wondering if there are any other methods I could explore?

This is precisely what services are for – see Services Implementation Guide . In a nutshell, you make an app and register it as a service provider. You advertise your service using Info.plist where you specify NSStringPboardType as both the sender and return type. The user will then be able to right-click on a text selection in any app and choose your service from the popup menu.
