[英]Xamarin iOS iPad App is crashing, unexplained
我们正在使用Xamarin创建一个大型iOS应用程序。 几天以来,我们遇到的问题是应用程序以绝对意想不到的方式崩溃。 我们没有从Xamarin调试器获取日志,它是完全空的。 只有停止按钮切换到播放;)我们唯一拥有的是附加的XCode控制台日志。 但对我来说,找不到发生的事情是不可能的。
问题不可重现,它发生在应用程序的不同位置。 有人看到了类似的问题并找到了解决方案吗?

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

您似乎在介绍一些将在编译器时间之前解析的代码。 它可以在Android(JIT just-in编译器时间)中使用,但不适用于iOS(AOT提前)。 阅读Xamarin在他的页面中写到的内容http://docs.xamarin.com/guides/ios/advanced_topics/limitations/
由于iPhone的内核阻止应用程序动态生成代码,因此iPhone上的Mono不支持任何形式的动态代码生成。
希望我帮忙!
