Transparent UITableView on top of several UIViewController and OpenGLView (Cocos2D) - objective-c

Question

Here is my code :
// View Controller with navigation bar
InAppPurchaseViewController *purchaseViewController = [[InAppPurchaseViewController alloc] init];
purchaseViewController.title = #"Magasin";
purchaseViewController.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(dismissViewController:)] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:purchaseViewController] autorelease];
// Add `purchaseViewcontroller` TO container AND container ON openGLView
UIViewController *container = [[UIViewController alloc] init];
[container setView:[[CCDirector sharedDirector] openGLView]];
[container setModalTransitionStyle: UIModalTransitionStyleCoverVertical];
[container presentViewController:navController animated:YES completion:nil];
The UITableView is in purchaseViewController.
I was thinking of using [UIColor clearColor], BUT whatever I use it on I get a BLACK background on my UITableView. The cells get unselectable and unslidable (apart from the elements that are into the cells)
EDIT : The appdelegate
Here is the .h
#class AudioEngine;
#class RootViewController;
#class Score;
#interface AppDelegate : NSObject <UIApplicationDelegate, GameCenterManagerDelegate>
#property int CurrentPackage;
#property int CurrentScore;
#property int CurrentHighScore;
#property BOOL SoundShouldPlay;
#property BOOL PauseScreenUp;
#property(nonatomic, retain) AudioEngine *CustomAudioEngine;
#property(nonatomic, retain) GameCenterManager *CustomGameCenterManager;
#property(nonatomic, retain) UIWindow *window;
#property(nonatomic, readonly) RootViewController *ViewController;
#property(nonatomic, retain) NSString* CurrentLeaderBoard;
#property(nonatomic, retain) NSMutableArray *TenLastScoresArray;
+(AppDelegate *)get;
-(void)connectToGameCenter;
-(void)addScoreToLastScore:(Score*)score;
And the method did finish launching
-(void)applicationDidFinishLaunching:(UIApplication*)application
{
CC_DIRECTOR_INIT();
self.CurrentLeaderBoard = kLeaderboardID;
[[SKPaymentQueue defaultQueue] addTransactionObserver:[InAppPurchaseSingleton sharedHelper]];
[AudioEngine preloadBackgroundMusic];
[AudioEngine playBackgroundMusic:3];
self.SoundShouldPlay = YES;
[SceneManager goSplash];
}

Answer 1

Instead of presenting the view controller on container:
UIViewController *container = [[UIViewController alloc] init];
...
[container presentViewController:navController animated:YES completion:nil];
what should work is presenting it on the root view controller that the cocos2D template created for you. It is normally accessible through the app delegate:
UIViewController *rootViewController = (UIViewController*)[(YOURAPPDELEGATE*)[[UIApplication sharedApplication] delegate] viewController];
[rootViewController presentViewController:navController animated:YES completion:nil];
viewController is an ivar that the cocos2D default template add to the application delegate class. It is normally private, so you will need to define an accessor:
#property (nonatomic, readonly) RootViewController *viewController; //-- .h file
#synthesize viewController; //-- .m file
Hope this helps.
EDIT:
Based on what I have in my app delegate, I think you could try and instantiate the RootViewController like this:
CC_DIRECTOR_INIT
ViewController = [[RootViewController alloc] initWithNibName:nil bundle:nil];
ViewController.wantsFullScreenLayout = YES;
[ViewController setView:[[CCDirector sharedDirector] openGLView]];
