Question

I am developing an app in Xcode on Mac and would like to know the event which is fired when the mac gets back from sleep.
AwakeFromNib doesn’t seem to work.

Just found it:

- (void) receiveWakeNote: (NSNotification*) note
{
    NSLog(@"receiveSleepNote: %@", [note name]);
}

- (void) fileNotifications
{
    //These notifications are filed on NSWorkspace's notification center, not the default 
    // notification center. You will not receive sleep/wake notifications if you file 
    //with the default notification center.
     [[[NSWorkspace sharedWorkspace] notificationCenter] addObserver: self 
                                                           selector: @selector(receiveWakeNote:) 
                                                               name: NSWorkspaceDidWakeNotification object: NULL];
}
