我在哪里可以find一个Mac虚拟键码的列表？
我正在使用CGEventCreateKeyboardEvent ，需要知道使用什么CGKeyCode值。
具体来说，我是在Command键的关键代码之后。 文档给出了其他键的例子： z是6 ， shift是56 。
必须有某个Mac虚拟键码的列表？
更多的规范引用在<HIToolbox/Events.h> ：
/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HIToolbox.framework/Versions/A/Headers/Events.h
以下是从Events.h获取的用于快速参考的公共密钥代码的列表。
如果您需要在应用程序中使用这些键码，则应该包含Carbon框架：
Objective-C的：
#include <Carbon/Carbon.h>
迅速：
import Carbon.HIToolbox
然后可以直接使用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。 常量中的字母只对应于美国的QWERTY键盘布局。
例如，在左轮手指上的左手指键：
QWERTY keyboard layout > s > kVK_ANSI_S > "s"
Dvorak keyboard layout > o > kVK_ANSI_S > "o"
这里讨论了键码到string布局无关转换的策略，反之亦然。
如何将ASCII字符转换为CGKeyCode？
来自Events.h ：
/* * 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. */ enum { kVK_ANSI_A = 0x00, kVK_ANSI_S = 0x01, kVK_ANSI_D = 0x02, kVK_ANSI_F = 0x03, kVK_ANSI_H = 0x04, kVK_ANSI_G = 0x05, kVK_ANSI_Z = 0x06, kVK_ANSI_X = 0x07, kVK_ANSI_C = 0x08, kVK_ANSI_V = 0x09, kVK_ANSI_B = 0x0B, kVK_ANSI_Q = 0x0C, kVK_ANSI_W = 0x0D, kVK_ANSI_E = 0x0E, kVK_ANSI_R = 0x0F, kVK_ANSI_Y = 0x10, kVK_ANSI_T = 0x11, kVK_ANSI_1 = 0x12, kVK_ANSI_2 = 0x13, kVK_ANSI_3 = 0x14, kVK_ANSI_4 = 0x15, kVK_ANSI_6 = 0x16, kVK_ANSI_5 = 0x17, kVK_ANSI_Equal = 0x18, kVK_ANSI_9 = 0x19, kVK_ANSI_7 = 0x1A, kVK_ANSI_Minus = 0x1B, kVK_ANSI_8 = 0x1C, kVK_ANSI_0 = 0x1D, kVK_ANSI_RightBracket = 0x1E, kVK_ANSI_O = 0x1F, kVK_ANSI_U = 0x20, kVK_ANSI_LeftBracket = 0x21, kVK_ANSI_I = 0x22, kVK_ANSI_P = 0x23, kVK_ANSI_L = 0x25, kVK_ANSI_J = 0x26, kVK_ANSI_Quote = 0x27, kVK_ANSI_K = 0x28, kVK_ANSI_Semicolon = 0x29, kVK_ANSI_Backslash = 0x2A, kVK_ANSI_Comma = 0x2B, kVK_ANSI_Slash = 0x2C, kVK_ANSI_N = 0x2D, kVK_ANSI_M = 0x2E, kVK_ANSI_Period = 0x2F, kVK_ANSI_Grave = 0x32, kVK_ANSI_KeypadDecimal = 0x41, kVK_ANSI_KeypadMultiply = 0x43, kVK_ANSI_KeypadPlus = 0x45, kVK_ANSI_KeypadClear = 0x47, kVK_ANSI_KeypadDivide = 0x4B, kVK_ANSI_KeypadEnter = 0x4C, kVK_ANSI_KeypadMinus = 0x4E, kVK_ANSI_KeypadEquals = 0x51, kVK_ANSI_Keypad0 = 0x52, kVK_ANSI_Keypad1 = 0x53, kVK_ANSI_Keypad2 = 0x54, kVK_ANSI_Keypad3 = 0x55, kVK_ANSI_Keypad4 = 0x56, kVK_ANSI_Keypad5 = 0x57, kVK_ANSI_Keypad6 = 0x58, kVK_ANSI_Keypad7 = 0x59, kVK_ANSI_Keypad8 = 0x5B, kVK_ANSI_Keypad9 = 0x5C }; /* keycodes for keys that are independent of keyboard layout*/ enum { kVK_Return = 0x24, kVK_Tab = 0x30, kVK_Space = 0x31, kVK_Delete = 0x33, kVK_Escape = 0x35, kVK_Command = 0x37, kVK_Shift = 0x38, kVK_CapsLock = 0x39, kVK_Option = 0x3A, kVK_Control = 0x3B, kVK_RightShift = 0x3C, kVK_RightOption = 0x3D, kVK_RightControl = 0x3E, kVK_Function = 0x3F, kVK_F17 = 0x40, kVK_VolumeUp = 0x48, kVK_VolumeDown = 0x49, kVK_Mute = 0x4A, kVK_F18 = 0x4F, kVK_F19 = 0x50, kVK_F20 = 0x5A, kVK_F5 = 0x60, kVK_F6 = 0x61, kVK_F7 = 0x62, kVK_F3 = 0x63, kVK_F8 = 0x64, kVK_F9 = 0x65, kVK_F11 = 0x67, kVK_F13 = 0x69, kVK_F16 = 0x6A, kVK_F14 = 0x6B, kVK_F10 = 0x6D, kVK_F12 = 0x6F, kVK_F15 = 0x71, kVK_Help = 0x72, kVK_Home = 0x73, kVK_PageUp = 0x74, kVK_ForwardDelete = 0x75, kVK_F4 = 0x76, kVK_End = 0x77, kVK_F2 = 0x78, kVK_PageDown = 0x79, kVK_F1 = 0x7A, kVK_LeftArrow = 0x7B, kVK_RightArrow = 0x7C, kVK_DownArrow = 0x7D, kVK_UpArrow = 0x7E };
Macintosh Toolbox Essentials演示了Figure 2-10 Apple Extended Keyboard II的这些虚拟键码的物理位置：
在这里find答案。
所以：
- 命令键是55
- class次是56
- 大写locking57
- 选项是58
- 控制是59。
这里是所有的键码。 你可以从那里看…或者在名为“Key Codes”的mac appstore中有一个应用程序下载它，它可以显示你按下某个键的键码。
