我正在使用 SpriteBuilder(与 Cocos2d v3.0 集成).我构建了一个应用程序，现在我想在最顶部放置一个 iAd，当我调用它时它会弹出，当我告诉它时它会隐藏.最简单的方法是什么?

I am using SpriteBuilder (which integrates with Cocos2d v3.0). I built an app and now I want to put in an iAd at the very top that pops up when I call it, and hides when I tell it to. What's the simplest way to do this?

请记住，我将 SpriteBuilder 与 Cocos2d 一起使用.仅仅因为我使用 SpriteBuilder 并不意味着我也没有使用 Xcode 5.我也完全参与了 Xcode.SpriteBuilder 不会为我编写代码，我会这样做.

Keep in mind I am using SpriteBuilder with Cocos2d. And just because I am using SpriteBuilder does not mean I am not using Xcode 5 as well. I am fully involved in Xcode as well. SpriteBuilder does not write the code for me, I do that.

推荐答案

将 iAd 框架添加到您的依赖项中.

Add iAd framework to your dependencies.

在游戏场景的头文件中，添加 ADBannerViewDelegate，例如:

In your header file for your game scene, add the ADBannerViewDelegate, for instance:

@interface MainScene : CCNode <CCPhysicsCollisionDelegate, ADBannerViewDelegate>

在你的实现文件中，添加实例变量_bannerView:

In your implementation file, add the instance variable _bannerView:

@implementation MainScene {
    ADBannerView *_bannerView;
}    

最后，插入 iAD 代码(通过一些 cocos2d 调整).这是我对带有顶部横幅的纵向模式游戏的实现.没有 hide 方法，但很容易实现.

And finally, insert the the iAD code (with some cocos2d tweaks). Here's my implementation for a game in portrait mode with a top banner. There's no hide method, but it's pretty easy to implement.

# pragma mark - iAd code

-(id)init
{
    if( (self= [super init]) )
    {
        // On iOS 6 ADBannerView introduces a new initializer, use it when available.
        if ([ADBannerView instancesRespondToSelector:@selector(initWithAdType:)]) {
            _adView = [[ADBannerView alloc] initWithAdType:ADAdTypeBanner];

        } else {
            _adView = [[ADBannerView alloc] init];
        }
        _adView.requiredContentSizeIdentifiers = [NSSet setWithObject:ADBannerContentSizeIdentifierPortrait];
        _adView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
        [[[CCDirector sharedDirector]view]addSubview:_adView];
        [_adView setBackgroundColor:[UIColor clearColor]];
        [[[CCDirector sharedDirector]view]addSubview:_adView];
        _adView.delegate = self;
    }
    [self layoutAnimated:YES];
    return self;
}


- (void)layoutAnimated:(BOOL)animated
{
    // As of iOS 6.0, the banner will automatically resize itself based on its width.
    // To support iOS 5.0 however, we continue to set the currentContentSizeIdentifier appropriately.
    CGRect contentFrame = [CCDirector sharedDirector].view.bounds;
    if (contentFrame.size.width < contentFrame.size.height) {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierPortrait;
    } else {
        _bannerView.currentContentSizeIdentifier = ADBannerContentSizeIdentifierLandscape;
    }

    CGRect bannerFrame = _bannerView.frame;
    if (_bannerView.bannerLoaded) {
        contentFrame.size.height -= _bannerView.frame.size.height;
        bannerFrame.origin.y = contentFrame.size.height;
    } else {
        bannerFrame.origin.y = contentFrame.size.height;
    }

    [UIView animateWithDuration:animated ? 0.25 : 0.0 animations:^{
        _bannerView.frame = bannerFrame;
    }];
}

- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
    [self layoutAnimated:YES];
}

- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
    [self layoutAnimated:YES];
}
