我在哪里可以找到Mac虚拟密钥代码列表？

我正在使用CGEventCreateKeyboardEvent，需要知道要使用的CGKeyCode值。

具体来说，我在 Command 键的关键代码之后。文档提供了其他键的示例： z 是6， shift 是56。

某处必须有一个Mac虚拟密钥代码列表？

以下是快速参考的常用密钥代码列表，摘自Events.h。

如果您需要在应用程序中使用这些密钥代码，则应包括Carbon框架：

目标-C：
#include <Carbon/Carbon.h>

夫特：
import Carbon.HIToolbox

然后，您可以直接使用kVK_ANSI_A常量。

警告

键常量引用键盘上的物理键。如果打字员使用不同的键盘布局，他们的输出会改变。常量中的字母仅对应于美国QWERTY键盘布局。

例如，本垒打上的左手无名键：

QWERTY keyboard layout＆gt; s ＆gt; kVK_ANSI_S＆gt; "s"
Dvorak keyboard layout＆gt; o ＆gt; kVK_ANSI_S＆gt; "o"

此处讨论了将键码与布局无关的转换为字符串的策略，反之亦然：

/*
 *  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.
