MonoTouch在设备上随机崩溃,而不是在模拟器上

Question

我认为这在某种程度上与记忆有关,但我已经做了我能想到的一切.我确保课程处置财产.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获得GC的内容等.

基本上该应用程序在模拟器中工作正常,但在真实设备上的同一位置崩溃.好像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.线程太多了？

该行之前通常有一个异常类型和消息：

堆栈跟踪：

它通常可以很好地提示问题。现在本机堆栈跟踪也在这里提供了线索：

0x01e394ac monoeg_g_log + 208 6 TrackAboutIOS

0x01d11664 get_numerous_trampoline + 160 7 TrackAboutIOS

第一行告诉我们日志中打印了一些内容（或者至少尝试打印）。如果您检查设备的日志（例如使用 Xcode 或mtouch --logdev），您应该会看到该消息。

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）。以下是有关如何增加适用于您的应用程序的蹦床数量的说明。

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。
