我有这个代码（下面）来创建一个可定制的热键。

OSStatus MyHotKeyHandler(EventHandlerCallRef nextHandler,EventRef theEvent,void *userData)
{
    EventHotKeyID hkCom;
    GetEventParameter(theEvent,kEventParamDirectObject,typeEventHotKeyID,NULL,sizeof(hkCom),NULL,&hkCom);
    HotKeyController *controller = (HotKeyController *)userData;
    int l = hkCom.id;
    switch (l) {
        case 1: [controller->window makeKeyAndOrderFront:NSApp];  
            break;
        case 2: [controller->searchWindow makeKeyAndOrderFront:nil];
            break;
        case 3: [controller->entryWindow makeKeyAndOrderFront:nil];
            break;  
    }
    return noErr;
}

- (void)awakeFromNib
{
    //Register the Hotkeys
    EventHotKeyRef gMyHotKeyRef;
    EventHotKeyID gMyHotKeyID;
    EventTypeSpec eventType;
    eventType.eventClass=kEventClassKeyboard;
    eventType.eventKind=kEventHotKeyPressed;


    InstallApplicationEventHandler(&MyHotKeyHandler,1,&eventType,(void *)self,NULL);

    gMyHotKeyID.signature='htk1';
    gMyHotKeyID.id=1;
    if([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeMain"]!=-999) {
        RegisterEventHotKey([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeMain"], [[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyModifiersMain"], gMyHotKeyID, GetApplicationEventTarget(), 0, &gMyHotKeyRef);
    }

    gMyHotKeyID.signature='htk2';
    gMyHotKeyID.id=2;
    if([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeSearch"]!=-999) {
        RegisterEventHotKey([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeSearch"], [[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyModifiersSearch"], gMyHotKeyID, GetApplicationEventTarget(), 0, &gMyHotKeyRef);
    }

    gMyHotKeyID.signature='htk3';
    gMyHotKeyID.id=3;
    if([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeEntry"]!=-999) {
        RegisterEventHotKey([[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyCodeEntry"], [[NSUserDefaults standardUserDefaults] integerForKey:@"hotkeyModifiersEntry"], gMyHotKeyID, GetApplicationEventTarget(), 0, &gMyHotKeyRef);
    }

}

但是代码是通过弹出框使热键可自定义的，我将如何制作它以便它可以与快捷记录器 按钮或字段一起使用。在他们的示例应用程序中（来自编写代码的人），他们使用了一个通过操作连接到控制器的弹出框来选择热键和连接到 NSUserDefaultsController 的文本字段来显示它。我如何让快捷方式记录器字段/按钮选择热键，因为目前我将操作和用户默认控制器连接到它，但它不起作用（即使热键工作）。需要如何更改代码以使其工作或使其执行应做的事情？

您需要从 SRRecorderControl 获取 KeyCombo。它具有修饰符标志和虚拟键码，您将在 Carbon Event 热键中使用它们。在将修饰符标志传递给RegisterEventHotKey.

您将在 SRRecorderControl 和 SRCommon 标头中找到所有这些内容。
