Objective-C:聆听键盘快捷键并对其进行操作 [英] Objective-C: Listen to keyboard shortcuts and act on them

问题描述

我正在为Mac OS X开发一个应用程序，我需要听键盘快捷键输入，以便可以对它们进行操作.

I am developing an app for Mac OS X and I need to listen to keyboard shortcut inputs so I can act on them.

例如:

• 上键和下键在表视图上上下移动.
• ⌘ + ⌦删除项目.
• ⌘ + ⇧ + N 创建一个新项目.

• Up and down keys move up and down on a table view.
• ⌘ + ⌦ drops an item.
• ⌘ + ⇧ + N creates a new item.

不应仅限于焦点控件上的事件.

It shouldn't be restricted to events on the focused control.

有什么想法吗?

谢谢.

推荐答案

看看

Have a look at the Cocoa Event-Handling Guide. There are a few places you can intercept events before they get to the key view. You can intercept all events in the application by overriding -[NSApplication sendEvent:], or you can intercept events at a per-window level by overriding-[NSWindow sendEvent:].
