这个应用程序是几个月前发布的，在 iOS 4/5 中完美运行。现在在 iOS 6 中的某些屏幕上出现崩溃。
相当容易实现。在 xib 中有一个 AdBannerView。我把它连到了代表处。让我的 delagate 方法显示/隐藏广告。这是崩溃数据。
异常类型:EXC_CRASH (SIGABRT)

如果我取消连接 AdBannerView，它就可以工作。重新接线并崩溃。我在这个特定的 Controller 中没有任何字典。实际上，它只有 6 个通向其他屏幕的按钮。真正奇怪的是，代码在其他屏幕的其他地方使用，但工作正常。显然，它以前工作得很好。
最佳答案
让我澄清一下，在 iOS 6 中，AdBannerView 不推荐使用一些属性和方法。我认为这应该是你崩溃的原因。
请检查这个
