崩潰僅與iPad（模擬器或設備） - [__NSArrayM insertObject：atIndex：]

我嘗試測試的iPhone（不通用）的應用程序在iPad（設備和仿真器），但我得到這個錯誤：崩潰僅與iPad（模擬器或設備） - [__NSArrayM insertObject：atIndex：]

如果我得到iADSuite示例代碼，並且我從通用更改爲iphone，然後在ipad上測試該應用程序（設備或模擬器），我得到相同的錯誤。問題在哪裏？

編輯：代碼：

我刪除了我以前的答案，我發佈這個新的答案，而不是。

看看堆棧跟蹤。該問題是由於調用：

_bannerView.delegate = self;

這導致調用鏈導致的BannerViewController的loadView方法，同時仍然在initWithContentViewController:中間執行被調用。但在這一點上，伊娃尚未設定。

鑑於設置委託啓動廣告加載和需要查看，最好的解決方案是等待並設置viewDidLoad方法中的_bannerView.delegate。

另一種解決方案是在initWithContentViewController:方法重新排列來電：

- (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; 
}

另一種解決辦法是擺脫loadView執行和把所有的代碼（減去創建內容視圖）在viewDidLoad的開頭。

以這種方式應用程序不會崩潰，同時僅在_contentController = contentController;但現在的應用程序不顯示橫幅....我嘗試了很多時間，沒有什麼，如果我嘗試pp在iPhone模擬器上我得到的橫幅！ – kikko088 2013-02-10 13:16:55

我發現蘋果公司的這個說明：「在iPad上以兼容模式運行的iPhone應用程序不會在兼容環境中運行的部署應用程序中顯示測試廣告，或者在部署的應用程序中顯示實時廣告。所有的客戶，確保你已經開發出一個支持所有可能的設備的應用程序。「這是否意味着在2x模式下iAd不起作用？ – kikko088 2013-02-10 15:42:56

這對我有用。 – Robert 2013-03-06 02:05:04

如果沒有代碼，其確切的問題，打好我不能指出，但錯誤很明顯：你試圖插入一個「無」對象到NSMutableArray中，但是這個類不允許它！

NS數組和字典無法將nil存儲爲值：如果您這樣做，應用程序會產生異常（並且如果您不處理應用程序崩潰）。

編輯：從調用堆棧，你看到的錯誤是：

6 iFormularioNew_Free     0x0003a27c -[BannerViewController loadView] + 348

所以你應該看的loadView方法，在線路：

[self addChildViewController:_contentController];

我敢肯定，當它崩潰_contentController爲零（addChildViewController將控制器添加到由父級擁有的子控制器數組）。我留給你發現爲什麼它爲零;）

該代碼有點長，但錯誤在這裏：_bannerViewController = [[BannerViewController alloc] initWithContentViewController：self.tabBarController]; self.window.rootViewController = _bannerViewController;我認爲你更好地理解下載這個問題：http://developer.apple。com/library/ios /＃samplecode/iAdSuite/Introduction/Intro.html，將SplitNavigationBanner僅用於iPhone，並在iPad模擬器中打開。現在我編輯我的問題 – kikko088 2013-02-09 15:19:39

問題在這裏，如果（[ADBannerView instancesRespondToSelector：@selector（initWithAdType :)]）{_bannerView = [[ADBannerView alloc] initWithAdType：ADAdTypeBanner]; }如果我評論這行應用程序不會崩潰！問題是爲什麼？:( – kikko088 2013-02-10 01:04:32

橫幅也可以在模擬器上運行（只是你沒有得到一個真正的廣告，只是一個「佔位符」，顯示你的一切都是正確的），但你必須指定你想獲得的橫幅類型iPhone/iPad ...），所以有時你應該什麼也得不到。 – 2013-02-11 13:33:18
