SpriteKit- the right way to multitask

Question

I tried to search everywhere in the code:Explained documentry what it does when going to background, or if it is even paused sometime, but to no avail- can someone direct me

Answer 1

I was wondering why in the world this seemingly simple solution was causing me crashes on app startup, but it was because I had iAd running. So, a thing to keep in mind: @MassivePenguin's answer works but if you have iAd going you will have to grab the SKView via the subviews or it (obviously) crashes.

-(SKView*)getSKViewSubview{
    for (UIView* s in self.window.rootViewController.view.subviews) {
        if ([s isKindOfClass:[SKView class]]) {
            return (SKView*)s;
        }
    }
    return nil;
}

- (void)applicationWillResignActive:(UIApplication *)application {    
    SKView* view = [self getSKViewSubview];

    if (view) {
        view.paused = YES;
    }

}

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    SKView* view = [self getSKViewSubview];

    if (view) {
        view.paused = NO;
    }

}
