Question

我在下面有这个代码，我在正常的Cocoa应用程序中实现了HotKeys。但是，当我尝试在命令行工具应用程序中实现相同的操作时，按下键时不会调用“OSStatus MyHotKeyHandler（EventHandlerCallRef nextHandler，EventRef theEvent，void * userData）”方法。我不明白我错过了什么。谁能发现错误？我哪里错了？提前感谢你。。

#import "MainController.h"
@implementation MainController
@synthesize window = mWindow;

-(id)init
{
self = [super init];
if (self != nil) {

NSMutableDictionary *userDefaultsValuesDict = [NSMutableDictionary dictionary];
[userDefaultsValuesDict setObject:[NSNumber numberWithInt:123]forKey:@"hotkeyCodePlay"];
[userDefaultsValuesDict setObject:[NSNumber numberWithInt:cmdKey+optionKey]forKey:@"hotkeyModifiersPlay"];
[userDefaultsValuesDict setObject:[NSNumber numberWithInt:124]forKey:@"hotkeyCodeNext"];
[userDefaultsValuesDict setObject:[NSNumber numberWithInt:cmdKey+optionKey]forKey:@"hotkeyModifiersNext"];

[[NSUserDefaults standardUserDefaults] registerDefaults:userDefaultsValuesDict];      
[[NSUserDefaults standardUserDefaults] synchronize];
}
return self;
}

-(void)awakeFromNib
{
//Register the Hotkeys
EventHotKeyRef gMyHotKeyRef;
EventHotKeyID gMyHotKeyID;
EventTypeSpec eventType;
eventType.eventClass=kEventClassKeyboard;
eventType.eventKind=kEventHotKeyPressed;
OSStatus status = InstallApplicationEventHandler(&MyHotKeyHandler,1,&eventType,(void*)self,NULL);

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

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

 OSStatus MyHotKeyHandler(EventHandlerCallRef nextHandler,EventRef theEvent, void *userData)
 {
EventHotKeyID hkCom;
GetEventParameter(theEvent,kEventParamDirectObject,typeEventHotKeyID,NULL, sizeof(hkCom),NULL,&hkCom);
int l = hkCom.id;
MainController *selfObject  = (MainController *)userData;


switch (l) {
    case 1: //do something
        NSLog (@"HOTKEY 1 PRESSED");
        break;
    case 2: //do something
        [selfObject.window orderFrontRegardless];
        NSLog (@"HOTKEY 2 PRESSED");
        break;
}
return noErr;
}
@end
