macos - 将 key 代码转换为等效 key

如何将诸如kVK_ANSI_1之类的关键代码转换为可以传递给setKeyEquivalent的字符串(因此，对于kVK_ANSI_1，我会得到@"1")？而且为什么有​​两种方法可以指定 key ？仅具有一个表示会更有意义。

最佳答案

我最终使用了发现的here以下函数。

/* Returns string representation of key, if it is printable.
 * Ownership follows the Create Rule; that is, it is the caller's
 * responsibility to release the returned object. */
CFStringRef createStringForKey(CGKeyCode keyCode)
{
    TISInputSourceRef currentKeyboard = TISCopyCurrentKeyboardInputSource();
    CFDataRef layoutData =
        TISGetInputSourceProperty(currentKeyboard,
                                  kTISPropertyUnicodeKeyLayoutData);
    const UCKeyboardLayout *keyboardLayout =
        (const UCKeyboardLayout *)CFDataGetBytePtr(layoutData);

    UInt32 keysDown = 0;
    UniChar chars[4];
    UniCharCount realLength;

    UCKeyTranslate(keyboardLayout,
                   keyCode,
                   kUCKeyActionDisplay,
                   0,
                   LMGetKbdType(),
                   kUCKeyTranslateNoDeadKeysBit,
                   &keysDown,
                   sizeof(chars) / sizeof(chars[0]),
                   &realLength,
                   chars);
    CFRelease(currentKeyboard);

    return CFStringCreateWithCharacters(kCFAllocatorDefault, chars, 1);
}
