Ios5 [PointInfoController endAppearanceTransition]：发送到已解除分配实例0x74d5e90的消息

我在这里需要一些帮助，我已经通过模态加载了一个视图，基本上我现在正试图忽略这个视图，但是在视图消失后它一直崩溃

它显示*-[PointInfoController endAppearanceTransition]：发送到释放实例0x74d5e90的消息

下面是.H文件：

我对这一切都不熟悉，我花了好几天时间研究同一个问题。除了我自己，一切都怪我！我发现我无意中释放了所提到的实例。在我的例子中，我已经将该实例放入SSLConnectionRef中，并将其释放。我不知道为什么在查看代码时会出现问题。无论如何，我认为您的编译器会抱怨您的[instance release]方法，因为这些方法不再被允许。出现问题是因为您和系统都在释放实例。你需要摆脱你的释放，一切都会好起来的
