I have a viewController with cocos scene which I push in my navigation controller. In this view controller I have this methods:
-(void) viewDidLoad
{
[super viewDidLoad];
[_cc3FrameView addSubview: [self createGLView]];
CC3Backgrounder.sharedBackgrounder.shouldRunTasksOnRequestingThread = YES;
}
- (void) viewWillAppear:(BOOL)animated
{
if (!sceneInitialized) {
sceneInitialized = YES;
[CCDirector.sharedDirector runWithScene: [[self makePanoramaScene] asCCScene]];
} else {
[CCDirector.sharedDirector resume];
}
[CCDirector.sharedDirector startAnimation];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[[self runningPanoramaScene] sceneWillShow];
});
}
-(AxPanoramaScene *)runningPanoramaScene
{
CCScene *scene = [CCDirector.sharedDirector runningScene];
AxPanoramaLayer *panoramaLayer = [scene.children lastObject];
AxPanoramaScene *panoramaScene = (AxPanoramaScene *)panoramaLayer.cc3Scene;
return panoramaScene;
}
-(void)viewWillDisappear:(BOOL)animated
{
[CCDirector.sharedDirector pause];
}
While I push this controller - everything is working, but when I pop this controller and push it again - I got the bright pink screen and continuos messages in log:

How to correctly push the controller with cocos scene several times? I changed the example from cocos sources to this code. What am I doing wrong here? Please, note - that my controller is not CCDirector - it just contains a view with Cocos scene - the realization is like CC3DemoMultiScene. Thanks!
Remember that the CCDirector is a UIViewController, but it is also a singleton, which give it some unique nuances.
For example, you seem to be invoking the createGLView method every time you want to replace your controller. If it follows the CC3DemoMultiScene design, this will try to recreate another CCGLView before the old one has been released from the CCDirector singleton.
It's generally best to treat the CCDirector and the CCGLView that you create for it as a self-contained reusable unit. As you pop the containing controller, leave everything as is, and simply add and remove the CCGLView from the view hierarchy each time.
