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

【中文标题】无法在以编程方式创建的窗口中单击 iAd - 未调用bannerViewActionShouldBegin？

【英文标题】：iAd cannot be clicked in programmatically created window - bannerViewActionShouldBegin not called?

【问题描述】：

在 ios 4.2 应用程序中，我以编程方式创建了一个窗口、视图控制器、UIView 和两个子视图：一个 EAGLView 和一个 ADBannerView。我的代码是标准 EAGLView 和 Apple 的 BasicAdBanner 代码的组合。

我可以看到 iAd 横幅，但无法“点击”它们 - 在设备上或在模拟器中。视图控制器实现了 ADBannerDelegate，并接收 bannerViewDidLoadAd 等消息，但从未接收到 bannerViewActionShouldBegin 消息。

用 UITextView 替换 EAGL 视图或仅使用 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视图控制器。任何帮助将不胜感激。

此外，我的视图不会像广告横幅示例那样自动旋转/调整大小，但这是一个不太紧迫的问题。

代码跟随-

AppDelegate：

- (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;

视图控制器：

- (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 ---

    // this indicates that the banner has been clicked.. confirm?
    NSLog(@"banner clicked: will %s application\n",willLeave?"leave":"cover");

    return YES;

【问题讨论】：

我删除了我的答案，因为他们都错了。希望您应该得到更多的关注，而不会出现我的错误答案。

似乎问题与尝试在 -layoutForCorrentOrientation(BOOL) 末尾设置或动画内容框架更改的代码有关。如果我只设置横幅框架的位置，我可以单击横幅，但如果我还尝试设置 glView 的框架并重新创建表面，横幅不会响应输入。

这个问题已经解决了我的旋转问题：***.com/questions/1299239/… -- 我必须使用 glview==main 视图设置我的控制器，并使用主视图来旋转横幅和任何其他重叠的按钮。然后，在我的***视图上调用 setNeedsLayout 修复了我无响应的按钮问题。

【参考方案1】：

只是重申一下forksandhope所说的，

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

要解决这个问题，请创建一个超级 UIView 并将您的 UIView 和 ADView 添加到此视图。

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;

然后在加载广告时，将 ADView 添加到超级视图中：

- (void)showBannerView:(ADBannerView *)bannerView animated:(BOOL)animated

     // ...

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

     // ...

然后根据需要布局您的视图

- (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;
    ];

    // ...

【讨论】：

优秀的解决方案！请在视图控制器中添加它。我知道它在问题中，但答案是独立的。谢谢！

【参考方案2】：

澄清： 似乎问题与尝试在 -layoutForCorrentOrientation(BOOL) 末尾设置或动画内容框架更改的代码有关。如果我只设置横幅框架的位置，我可以单击横幅，但如果我还尝试设置 glView 的框架并重新创建表面，则横幅不会响应输入。

//EDIT: contrary to my OP, this UIViewAnimateWithDuration code was not commented out!
// And finally animate the changes, running layout for the content view if required.
//[UIView animateWithDuration:animationDuration
//                 animations:^
//                     glView.frame = contentFrame;
//                     [glView layoutIfNeeded];
                     banner.frame = CGRectMake(bannerOrigin.x, bannerOrigin.y, banner.frame.size.width, banner.frame.size.height);
//                 ];

附加： 最后，问题是我有一个*** UIView (controller.view)，它有 glView 和横幅作为子视图。原来我需要打电话

[self.view setNeedsLayout]

让这个***视图更新它的边界，以便它允许按钮按下到横幅！ （信用转到Ephraim's answer 到 UIButtons 旋转后没有响应的帖子

【讨论】：

仅供参考，我最终将视图层次结构更改为：controller.view=controller.glview -> controller.parentView -> controller.banner .. parentView 是一个通用的 UIView，我用它来旋转显示器周围的横幅，因为我正在 GLES 矩阵操作中旋转 glview。
