“无回溯"的 iPhone 崩溃 [英] iPhone Crash with "No Backtrace"

问题描述

我的 iPhone 应用程序最近被 App Store 拒绝，因为它在启动时崩溃".但是，我无法重现此崩溃.该应用程序在模拟器和具有相同硬件和软件的设备上都能完美运行，Apple 对其进行了测试(运行 iOS 4 的 iPhone 3.1).他们发给我的崩溃日志说没有可用的回溯"，所以我无处可看我的代码.举个例子:

My iPhone app was recently rejected from the App Store "because it crashes on launch". However, I cannot reproduce this crash. The app works perfectly on both the simulator and a device with the same hardware and software Apple tested it on (iPhone 3.1 running iOS 4). The crash logs they sent me say "No Backtrace Available", so I have nowhere to look in my code. Here's an example:

我该如何开始调试?这可能是构建问题而不是编码错误吗?我可以从崩溃报告的ARM 线程状态"或二进制图像"部分提取任何有用的信息吗?

How can I begin debugging this? Is it possible this is a build issue rather than a coding bug? And can I extract any useful information from the "ARM Thread State" or the "Binary Images" portions of the crash report?

谢谢！

*更新:* 我第一次在另一部运行 iOS 4 的 iPhone 上安装了该应用程序，但仍然无法重现崩溃.我开始认为这是构建时参数(例如库或目标版本)的问题.根据崩溃报告，是否有可能执行了我的应用程序代码?

*update: * I have installed the app for the first time on another iPhone running iOS 4 and still cannot reproduce the crash. I'm beginning to think this is an issue with build-time parameters such as libraries or targeted versions. Based on the crash report, is it likely that any of my application's code was executed?

推荐答案

我无法重现崩溃.我弄乱了一些构建参数并重新提交并获得批准.

I was never able to reproduce the crash. I messed with a few build params and resubmitted and it was approved.
