iphone - 无法在以编程方式创建的窗口中单击 iAd - bannerViewActionShouldBegin 未调用？

Question

在 iOS 4.2 应用程序中，我以编程方式创建了一个窗口、 View Controller 、UIView 和两个 subview :EAGLView 和 ADBannerView。我的代码是标准 EAGLView 和 Apple 的 BasicAdBanner 代码的组合。

我能够看到 iAd 横幅，但无法“点击”它们 - 在设备上或模拟器中。 View Controller 实现 ADBannerDelegate，并接收 bannerViewDidLoadAd 等消息，但从未收到 bannerViewActionShouldBegin 消息。

用 UITextView 替换 EAGL View 或仅使用 ADBannerView 不会改变行为，因此我假设我的问题在于以编程方式创建窗口或 View Controller 。任何帮助将不胜感激。

此外，我的 View 不会像广告横幅示例那样自动旋转/调整大小，但这是一个不那么紧迫的问题。

代码如下-

应用委托(delegate):

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

    // let's enable multitouch and user interaction
    window.userInteractionEnabled=YES;
    window.multipleTouchEnabled=YES;
    window.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    window.autoresizesSubviews = YES;

    controller = [GLViewController alloc];
    window.rootViewController = controller;
    [window addSubview:controller.view];
    glView = [controller.glView retain];
    [window makeKeyAndVisible];

    return YES;
}

View Controller :

- (void)loadView 
{
    self.view = [[UIView alloc] initWithFrame:[UIScreen mainScreen].bounds];
}

-(void)viewDidLoad
{
    [super viewDidLoad];

    // I'd like to get device orientation notifications.
    //[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; 
    //[[NSNotificationCenter defaultCenter] addObserver:self                                        
    //                                       selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];

    // the GL VIEW I want.
    glView = [[EAGLView alloc] initWithFrame:[UIScreen mainScreen].bounds];
    glView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
    glView.userInteractionEnabled=NO;
    [self.view addSubview:glView];

    // testing with a textview
    //content = [[UITextView alloc] initWithFrame:[UIScreen mainScreen].bounds];
    //content.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin;
    //content.userInteractionEnabled=NO;
    //[self.view addSubview:content];

    if (self.banner==NULL)
        [self createADBannerView];

    [self layoutForCurrentOrientation:NO];
}

-(void)createADBannerView
{

    // --- WARNING ---
    // If you are planning on creating banner views at runtime in order to support iOS targets that don't support the iAd framework

    bannerView.hidden = YES;
    // Set the autoresizing mask so that the banner is pinned to the bottom

    // Depending on if the banner has been loaded, we adjust the content frame and banner location
    // to accomodate the ad being on or off screen.

只是重申 forksandhope 所说的话，

将 ADView 放在 UIView 中，然后修改两者的框架大小会导致 ADView 变得不可点击。

要解决这个问题，请创建一个 super UIView 并将您的 UIView 和 ADView 添加到该 View 。

例如:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    // initialize the content UIView and/or UIViewController
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    // copy the content view to a class data member
    _contentView = self.view;

    // create the super UIView
    self.view = [[UIView alloc] initWithFrame:_contentView.frame];

    // add the content view to the super view
    [self.view addSubview:_contentView];

    if (self) {
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willBeginBannerViewActionNotification:) name:BannerViewActionWillBegin object:nil];
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFinishBannerViewActionNotification:) name:BannerViewActionDidFinish object:nil];
    }

    return self;
}

然后当加载广告时，将 ADView 添加到 super View :

- (void)showBannerView:(ADBannerView *)bannerView animated:(BOOL)animated
{
     // ...

        // add the AdView to the super view
        [self.view addSubview:_adBanner.adBannerView];

     // ...

}

然后根据需要布局 View

- (void)layoutAnimated:(BOOL)animated
{
    // ...

    [UIView animateWithDuration:animated ? 0.4 : 0.0 animations:^{
        _adBanner.adBannerView.frame = _bannerFrame; 
        [self.view layoutIfNeeded];
       // update the content view AND NOT the super view
       _contentView.frame = _contentFrame;
    }];

    // ...

}
