ios - MonoTouch 在设备上随机崩溃，而不是在模拟器上

Question

我认为这与内存有关，但我已经做了我能想到的一切。我已经确保类是已处置的属性(property)。在类级别而不是函数范围内维护硬引用，用于在我使用它们时可能会被 GC 处理的事物等。

基本上，该应用程序在模拟器中运行良好，但在真实设备上的同一位置崩溃。似乎我得到了几个不同的堆栈，但它们都在同一个地方。

我在我的应用程序中使用了大量事件。线程太多？

Answer 1

通常有一个异常(exception) 类型 和 留言 行前:

Stacktrace:

它通常会很好地提示问题。现在 native 堆栈跟踪也在这里提供了一个线索:

0x01e394ac monoeg_g_log + 208 6 TrackAboutIOS

0x01d11664 get_numerous_trampoline + 160 7 TrackAboutIOS

第一行告诉我们在您的日志中打印了一些东西(或者至少它试图打印)。如果您检查设备的日志(例如使用 Xcode 或 mtouch --logdev )，您应该会看到消息。
下一行让我觉得你的蹦床用完了(错误消息会告诉你哪种类型)。这是 instructions关于如何增加可用于您的应用程序的蹦床数量。
注意:如果这与蹦床无关，请编辑您的问题以添加异常类型/消息和设备日志的内容。
