Answer 1

Here is a good example:

To pause:

- (void) applicationDidEnterBackground:(UIApplication *)application
{
    [[CCDirector sharedDirector] stopAnimation];
    [[CCDirector sharedDirector] pause];
}
- (void)applicationWillResignActive:(UIApplication *)application
{
    [[CCDirector sharedDirector] stopAnimation];
    [[CCDirector sharedDirector] pause];
}

When resuming:

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [[CCDirector sharedDirector] stopAnimation]; // call this to make sure you don't start a second display link!
    [[CCDirector sharedDirector] resume];
    [[CCDirector sharedDirector] startAnimation];
}
