NSUserNotification - How open the app when clicked - objective-c

Question

I'm using NSUserNotification to display notifications. This is working fine. The problem is that when you click on a notification:
The apps notifications are not removed from the notification center.
The app (when minimized) does not open.
Anyone familiar with the NSUserNotification who can offer some pointers?
notice.m
#import "Notice.h"
#implementation Notice
- (void) notify:(NSDictionary *)message {
NSLog(#"Notification - Show it");
NSUserNotification *notification = [[NSUserNotification alloc] init];
[notification setTitle:[message valueForKey:#"title"]];
[notification setInformativeText:[message valueForKey:#"content"]];
[notification setDeliveryDate:[NSDate dateWithTimeInterval:0 sinceDate:[NSDate date]]];
[notification setSoundName:NSUserNotificationDefaultSoundName];
NSUserNotificationCenter *center = [NSUserNotificationCenter defaultUserNotificationCenter];
[center scheduleNotification:notification];
}
- (void) userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification
{
NSLog(#"Notification - Clicked");
notification=nil;
[center removeDeliveredNotification: notification];
}
#pragma mark WebScripting Protocol
+ (BOOL) isSelectorExcludedFromWebScript:(SEL)selector
{
if (selector == #selector(notify:))
return NO;
return YES;
}
+ (NSString*) webScriptNameForSelector:(SEL)selector
{
id result = nil;
if (selector == #selector(notify:)) {
result = #"notify";
}
return result;
}
// right now exclude all properties (eg keys)
+ (BOOL) isKeyExcludedFromWebScript:(const char*)name
{
return YES;
}
#end
Thank you

Just implement the NSUserNotificationCenterDelegate and define this method:
- (void)userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification
Example:
This is what I did in a "notifier" application.
- (void) userNotificationCenter:(NSUserNotificationCenter *)center didActivateNotification:(NSUserNotification *)notification
{
NSRunAlertPanel([notification title], [notification informativeText], #"Ok", nil, nil);
}
- (void) userNotificationCenter:(NSUserNotificationCenter *)center didDeliverNotification:(NSUserNotification *)notification
{
notifications=nil;
[tableView reloadData];
[center removeDeliveredNotification: notification];
}
When the notification is activated (click by the user) I just inform the user with a panel (I could use a hud window).In this case I immediately remove the delivered notification, but this is not what happens usually.The notification could stay there some time and be removed after 1/2 hours (it depends on the application that you are developing).
