我正在尝试使用 Cocoa 创建游戏，我需要获取用户输入。似乎没有所有键码的可用列表。我应该使用键码吗？我找到了某些值，例如 NSUpArrowFunctionKey，但没有找到其他键。关于这个问题的更老的问题的答案都已经过时，使用 Carbon，链接已损坏。
我还没有找到类似枚举的东西，但这似乎包含了大多数（如果不是全部）数字键代码。

虚拟键码在 Events.h 中声明（/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/System/Library/Frameworks/Carbon.framework/Versions/ A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h)
讨论：
这些常量是最初在 Inside Mac Volume V, pg.1 中定义的虚拟键码。 V-191。他们识别键盘上的物理按键。名称中带有“ANSI”的常量根据 ANSI 标准美国键盘上的键位置进行标记。例如，kVK_ANSI_A 表示美式键盘布局中字母“A”键的虚拟键码。其他键盘布局可能在不同的物理键上有“A”键标签；在这种情况下，按“A”将生成不同的虚拟键码。
除了Willeke的回答之外，这里还有
Events.hCarbon.frameworkHIToolbox.framework/*
* Summary:
* Virtual keycodes
*
* Discussion:
* These constants are the virtual keycodes defined originally in
* Inside Mac Volume V, pg. V-191. They identify physical keys on a
* keyboard. Those constants with "ANSI" in the name are labeled
* according to the key position on an ANSI-standard US keyboard.
* For example, kVK_ANSI_A indicates the virtual keycode for the key
* with the letter 'A' in the US keyboard layout. Other keyboard
* layouts may have the 'A' key label on a different physical key;
* in this case, pressing 'A' will generate a different virtual
* keycode.

映射似乎有一些逻辑，我想这与硬件规格和按键接线有关。
