ios - 在 Sprite Kit 场景中隐藏 iAd

Question

我已使用以下代码将 iAds 添加到我的 Sprite Kit 游戏中:

在viewController.h文件中

@property (strong, nonatomic) IBOutlet ADBannerView * adBannerView;

在viewController.m文件中

- (void)viewWillLayoutSubviews
{
    [super viewWillLayoutSubviews];

    // Configure the view.
    SKView * skView = (SKView *)self.view;
    if (!skView.scene) {

        // Create and configure the scene.
        SKScene * scene = [MenuScene sceneWithSize:skView.bounds.size];
        scene.scaleMode = SKSceneScaleModeAspectFill;

        _adBannerView = [[ADBannerView alloc] initWithFrame:CGRectZero];
        _adBannerView.delegate = self;
        [_adBannerView setFrame:CGRectMake(0, 0, 460, 320)];
        [self.view addSubview:_adBannerView];

        // Present the scene.
        [skView presentScene:scene];
    }
}

这显示了每个场景中的 iAd。有没有办法在某些场景隐藏iAd？

Apple 的 iAd 编程指南说:

Only create a banner view when you intend to display it to the user. Otherwise, it may cycle through ads and deplete the list of available advertising for your application.

这在场景中完全可能吗？

是的，有一种方法可以在某些场景中隐藏 iAd。

- (void)viewDidLoad
{

    [super viewDidLoad];

     //Add view controller as observer
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:@"hideAd" object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleNotification:) name:@"showAd" object:nil];

    // Configure the view.
    SKView * skView = (SKView *)self.view;
    skView.showsFPS = NO;
    skView.showsNodeCount = NO;

    // Create and configure the scene.
    SKScene * scene = [MyScene sceneWithSize:skView.bounds.size];
    scene.scaleMode = SKSceneScaleModeAspectFill;

    // Present the scene.
    [skView presentScene:scene];
    self.canDisplayBannerAds = YES;

    adView = [[ADBannerView alloc] initWithFrame:CGRectZero];
    adView.frame = CGRectOffset(adView.frame, 0, 0.0f);
    adView.delegate=self;
    [self.view addSubview:adView];

    self.bannerIsVisible=NO;  
}
//Handle Notification
- (void)handleNotification:(NSNotification *)notification
{ 
    if ([notification.name isEqualToString:@"hideAd"]) {
        [self hidesBanner];
    } else if ([notification.name isEqualToString:@"showAd"]) {
        [self showBanner];
    }
}

在你想要隐藏横幅的场景中......

[[NSNotificationCenter defaultCenter] postNotificationName:@"showAd" object:nil]; 
//Sends message to viewcontroller to show ad.

[[NSNotificationCenter defaultCenter] postNotificationName:@"hideAd" object:nil];  
//Sends message to viewcontroller to hide ad.
