应用程序在使用仪器时，某些操作崩溃，如何找到原因？ [英] App crashes on certain actions when using instruments, how to find reason?

问题描述

我有一个应用程序导航控制器，几个子控制器。

I have an App with a Navigation Controller, several sub Controllers.

• 使用XCode调试我找不到任何错误。 / li>
  
• 在iPhone运行时，我无法找到任何错误。


• 使用仪器在模拟器上运行应用程序不会崩溃。 >
  
• 在iPhone上运行应用程序时，当我在某些ViewController之间单击退出时会崩溃。

我的老板也报告说他的iPod有时会崩溃，所以我很困惑现在。我应该如何进行？ （仍然是乐器的新手）。我如何找到什么使应用程序崩溃？
有没有办法在调试器旁边启动仪器？崩溃日志不告诉我很多，或者我不知道如何正确读取它们。

My boss also reported that on his iPod it crashes sometimes, so I'm quite confused now. How should I proceed ? (still quite new to instruments). How can I find out what makes the app crash ? Is there a way to launch instruments next to debugger ? Crash Logs don't tell me much, or maybe I don't know how to read them correctly.

推荐答案

仪器是混合。有时候有崩溃，我不能解释。当我不使用仪器时，其中一些崩溃不会发生。也就是说，工具还可以提供有用的信息，您的情况可能就是这些时间之一。

My experience with instruments is decidedly mixed. Sometimes there are crashes that I can't explain. And some of these crashes don't happen when I am not using instruments. That said, instruments can also provide useful information, and your situation may be one of those times.

根据您的描述，您可能有内存泄漏。所以我建议在模拟器上运行它的仪器来寻找泄漏。 [在xCode中，选择运行>使用性能工具运行>泄漏，然后单击仪器窗口中的泄漏面板。]

Based on your description, it is possible that you have memory leaks. So I would suggest running it on the simulator with instruments to look for leaks. [In xCode, select Run>Run with performance tool>leaks, then click on the leaks panel in the instruments window that comes up.]
