崩溃仅与iPad（模拟器或设备） - [__NSArrayM insertObject：atIndex：]

我尝试测试的iPhone（不通用）的应用程序在iPad（设备和仿真器），但我得到这个错误：崩溃仅与iPad（模拟器或设备） - [__NSArrayM insertObject：atIndex：]

如果我得到iADSuite示例代码，并且我从通用更改为iphone，然后在ipad上测试该应用程序（设备或模拟器），我得到相同的错误。问题在哪里？

编辑：代码：

我删除了我以前的答案，我发布这个新的答案，而不是。

看看堆栈跟踪。该问题是由于调用：

_bannerView.delegate = self;

这导致调用链导致的BannerViewController的loadView方法，同时仍然在initWithContentViewController:中间执行被调用。但在这一点上，伊娃尚未设定。

鉴于设置委托启动广告加载和需要查看，最好的解决方案是等待并设置viewDidLoad方法中的_bannerView.delegate。

另一种解决方案是在initWithContentViewController:方法重新排列来电：

- (instancetype)initWithContentViewController:(UIViewController *)contentController { 
    self = [super init]; 
    if (self != nil) { 
     // This must be called before you set the delegate on _bannerView 
     _contentController = contentController; 

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

    return self; 
}

另一种解决办法是摆脱loadView执行和把所有的代码（减去创建内容视图）在viewDidLoad的开头。

以这种方式应用程序不会崩溃，同时仅在_contentController = contentController;但现在的应用程序不显示横幅....我尝试了很多时间，没有什么，如果我尝试pp在iPhone模拟器上我得到的横幅！ – kikko088 2013-02-10 13:16:55

我发现苹果公司的这个说明：“在iPad上以兼容模式运行的iPhone应用程序不会在兼容环境中运行的部署应用程序中显示测试广告，或者在部署的应用程序中显示实时广告。所有的客户，确保你已经开发出一个支持所有可能的设备的应用程序。“这是否意味着在2x模式下iAd不起作用？ – kikko088 2013-02-10 15:42:56

这对我有用。 – Robert 2013-03-06 02:05:04

如果没有代码，其确切的问题，打好我不能指出，但错误很明显：你试图插入一个“无”对象到NSMutableArray中，但是这个类不允许它！

NS数组和字典无法将nil存储为值：如果您这样做，应用程序会产生异常（并且如果您不处理应用程序崩溃）。

编辑：从调用堆栈，你看到的错误是：

6 iFormularioNew_Free     0x0003a27c -[BannerViewController loadView] + 348

所以你应该看的loadView方法，在线路：

[self addChildViewController:_contentController];

我敢肯定，当它崩溃_contentController为零（addChildViewController将控制器添加到由父级拥有的子控制器数组）。我留给你发现为什么它为零;）

该代码有点长，但错误在这里：_bannerViewController = [[BannerViewController alloc] initWithContentViewController：self.tabBarController]; self.window.rootViewController = _bannerViewController;我认为你更好地理解下载这个问题：http://developer.apple。com/library/ios /＃samplecode/iAdSuite/Introduction/Intro.html，将SplitNavigationBanner仅用于iPhone，并在iPad模拟器中打开。现在我编辑我的问题 – kikko088 2013-02-09 15:19:39

问题在这里，如果（[ADBannerView instancesRespondToSelector：@selector（initWithAdType :)]）{_bannerView = [[ADBannerView alloc] initWithAdType：ADAdTypeBanner]; }如果我评论这行应用程序不会崩溃！问题是为什么？:( – kikko088 2013-02-10 01:04:32

横幅也可以在模拟器上运行（只是你没有得到一个真正的广告，只是一个“占位符”，显示你的一切都是正确的），但你必须指定你想获得的横幅类型iPhone/iPad ...），所以有时你应该什么也得不到。 – 2013-02-11 13:33:18

崩溃仅与iPad（模拟器或设备） - [__NSArrayM insertObject：atIndex：]
