iPhone:如何查找不常见的设备崩溃? [英] iPhone:How to find infrequent device crash?
问题描述
我的源代码项目很少发生崩溃.尽管我已经尝试了很多次，但是我无法找到确切的可重复步骤.在设备上执行dubug期间，很难复制它，因为它发生在某个地方，有时甚至发生.在iPhone Xcode开发中，是否有任何日志在打印时导致设备崩溃(或其他任何工具/方式)以找出可能发生的确切位置?
I am getting infrequent crashes from my source code project. I couldn't find out the exact reproducible steps though i have tried to reproduce so many times. During dubug on the device is becoming very hard to reproduce it, because it happens somewhere and sometimes. Is there any logs printing while crashing the device (or) any other tools/way to find out exactly where could it happen, in iPhone Xcode development?
感谢并感谢您的帮助.
这是我的应用最新崩溃:有人可以找到任何原因吗?
Here is my app latest crash: Can someone find any reason?

推荐答案
您应该能够获得在崩溃日志中，您将具有堆栈跟踪该应用程序崩溃了.
In the crash log, you'll have a stack trace of what was happening when the application crashed.
在堆栈跟踪中浏览您所做的最后一件事.跟踪中的最后一件事可能是在您调用的框架方法内，因此将调用追溯到您的代码并将其用作起点.
Look through the stack trace for the last thing you were doing. The last thing in the trace will likely be within a framework method that you call, so trace the call back to your code and use that as the starting point.
一旦您知道崩溃在代码中的何处发生，请尝试考虑可能导致崩溃的原因.如果您在查看可能导致崩溃的原因时遇到问题，请在此处发布导致崩溃的行(以及环绕代码)，我们可能会对导致崩溃的原因有一些了解.
Once you know where in your code the crash occurred, try to think of what might have caused the crash. If you're having trouble seeing what might have caused the crash, post the line that lead to the crash (along with the surround code) here and we might have some insight as to what caused it.
If you're also looking for resources on what Xcode has to offer to debug, have a read of the Xcode Debugging Guide.
