AppKit framework and NSEvent.h in Cocoa Touch

I want to write a method that needs NSEvent defined, so I need NSEvent.h. The SDK I am using (3.1.3) doesn't seem to have NSEvent.h within its frameworks. I found that it is in AppKit.framework, which I have under /Developers. Using Xcode, I navigated to the location of this AppKit and added it. Now AppKit appear开发者_开发问答s in Xcode along with UIKit and so on in the Frameworks list, and when I open the AppKit framework's Headers in Xcode, it lists AppKit.h and NSEvent.h. Nonetheless, the lines:

 #import <AppKit/AppKit.h>
 #import <AppKit/NSEvent.h>

both produce "no such file or directory" messages.

Anyone know what's wrong?

AppKit and NSEvent are not part of the iOS SDK. That is, they can't be used on the iPhone, iPod, or iPad. Only on the Mac.
