SKScene Fails to deallocate memory resulting in bounded memory growth

Question

I have been struggling with this for days, for some reason my SKScenes are not deallocating correctly, this results in bounded memory growth as each time i exit and enter a

I could be wrong but I suspect your button class is your offender. When you call...

[testButton4 addTarget:self selector:@selector(buttonPressed:) withObject:[NSNumber numberWithInt:5] forControlEvent:AGButtonControlEventTouchUpInside];

You pass self being that scene. In the button class the method..

-(void)addTarget:(id)target selector:(SEL)selector withObject:(id)object forControlEvent:(AGButtonControlEvent)controlEvent
{
    //check whether selector is already saved, otherwise it will get called twice

    if (marrSelectors == nil)
    {
        marrSelectors = [NSMutableArray new];
    }

    NSMutableDictionary *mdicSelector = [[NSMutableDictionary alloc]init];

    [mdicSelector setObject:target forKey:@"target"];
    [mdicSelector setObject:[NSValue valueWithPointer:selector] forKey:@"selector"];

    if (object)
    {
        [mdicSelector setObject:object forKey:@"object"];
    }

    [mdicSelector setObject:[NSNumber numberWithInt:controlEvent] forKey:@"controlEvent"];

    [marrSelectors addObject:mdicSelector];
}

Note this..

[mdicSelector setObject:target forKey:@"target"];

target is your scene and it is being tossed into a dictionary in that is tossed into an array. So in theory that button now has a strong reference to your scene and your scene has a reference to that button.

To test this theory set all of your buttons to nil before calling

[self.view presentScene:theScene transition:theTransition];

And if I am correct that should break the strong reference to each other. Hopefully that helps and is the issue.
