macOS Event to stop the screensaver.

[DeDMakar]

Hi,
Is there a way that my application can immediately start to work when will stop screensaver.
Is there an Event or Notification or something like that I could use?
I need to define that moment when it is necessary to enter the passport and user.

I found:
* com.apple.screensaver.action (with userinfo {action=1})
* com.apple.screensaver.didstart (no userinfo)
* com.apple.screensaver.willstop (no userinfo)
* com.apple.screensaver.didstop (no userinfo)

How to use them correctly?

Assuming those notifications are correct and they're still being sent in Leopard (can't test right now), you would need to do this:

- (id)init {
    self = [super init];
    [[NSDistributedNotificationCenter defaultCenter] addObserver:self
        selector:@selector(screenSaverDidStop:)
        name:@"com.apple.screensaver.didstop" object:nil];
    return self;
}

- (void)screenSaverDidStop:(NSNotification *)notification {
    // do something here
}

Edit: if you're not using Cocoa you can use CFNotificationCenterGetDistributedCenter() and related functions instead.
