Question

after so much reading, i can see there is so much miss understanding on what should i do when replacing scene.
on the dealloc method, do i have to release ALL my timers ?? or cocos2d does it ??

i have 3 timers on startup:

[self schedule: @selector(contact:)];
[self schedule:@selector(tick:)]; 
[self schedule: @selector(randomsActions:) interval:0.1];

befor i replace the scene to menu (replaceScene) i do this :

[self unschedule:@selector(randomsActions:)] ; //stop timer
    [self unschedule:@selector(contact:)] ; //stop timer
    [self unschedule:@selector(contact:)] ; //stop timer

but it crashes.(i have seen people saying i do not have to unschedule them? )

so i tried this in my dealloc :

[[CCScheduler sharedScheduler] unscheduleAllSelectorsForTarget: self];

which crash it also at the second time( crashes in class: CCScheduler.m )

in my dealloc i put also this:( DO I NEED TO??? )

delete _contactListener;
[self removeAllChildrenWithCleanup:
YES];
delete world;
world = NULL;
[super dealloc];

whats happen here ?
can someone give me any idea on what should be done in dealloc when replacing scenes?
what should i do with my timers ???

thanks .

When you replace the scene, COCOS2d automatically dealloc all the scheduler you have started for the particular scene or layer. Thats why you wrote [self scheduler:…];.
Cocos2d Scheduler is somewhat different than NSTimer.

You do not need to dealloc the sccheduler just keep it blank, need not to worry,

- (void)dealloc {

    //memory deallocation  
[super dealloc];
}
