iAd reducing FPS?

问题

Does iAd banner reduces FPS?

Indeed, since I added iAd my FSP is shit. I was 59 all game and now it's variable from 35-50 FPS.

Any ideas please because my game is almost not playable with this banner.

Thank for help.

You should implement the iAd logic in your UINavigationController subclass that was set in the appDelegate. At mine code it look like:

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Create the main window
    window_ = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    CCGLView *glView = [CCGLView viewWithFrame:[window_ bounds]
                                   pixelFormat:kEAGLColorFormatRGB565
                                   depthFormat:0
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:NO
                               numberOfSamples:0];

    // Enable multiple touches
    [glView setMultipleTouchEnabled:YES];

    director_ = (CCDirectorIOS*) [CCDirector sharedDirector];

    director_.wantsFullScreenLayout = YES;

    // Display FSP and SPF
    [director_ setDisplayStats:YES];

    // set FPS at 60
    [director_ setAnimationInterval:1.0/60];

//FEW LINES LATER

    // Create a Navigation Controller with the Director
    navController_ = [[MyNavigationController alloc] initWithRootViewController:director_];
    navController_.navigationBarHidden = YES;

    [self checkDeviceType];

    // setup iAds bannerView
    [self setupIADs];

    // for rotation and other messages
    [director_ setDelegate:navController_];

    // set the Navigation Controller as the root view controller
    [window_ setRootViewController:navController_];

    // make main window visible
    [window_ makeKeyAndVisible];

    return YES;
}

- (void)setupIADs {
    CGSize size = [[CCDirector sharedDirector] winSize];

    float bannerHeight = _isiPadRunning ? 66.0f : 50.0f;
    ADAdType bannerType = _isiPadRunning ? ADAdTypeMediumRectangle : ADAdTypeBanner;
    _bannerView = [[ADBannerView alloc] initWithAdType:bannerType];
    _bannerView.frame = CGRectMake(0, navController_.view.frame.size.height, size.width, bannerHeight);

    CGSize newBannerSize = [_bannerView sizeThatFits:CGSizeMake(size.width, bannerHeight)];
    _bannerView.frame = CGRectMake(0, navController_.view.frame.size.height,
                                   newBannerSize.width, newBannerSize.height);
    _bannerView.delegate = self;

    //get view
    UIView *mainView = [navController_ view];
    [mainView addSubview:_bannerView];
    [mainView setNeedsLayout];
}

As you can see I use navController_ to place an iAd banner view. No FPS drops! :) Please, try it out. For me it helped and I have no FPS drops or delay. Everything works great.
