iOS 应用程序因未知原因崩溃

Question

我正在使用最新版本的 XCode 并为 iOS 6.0 及更高版本构建。以下是我得到的崩溃日志。好像一点用处也没有。我唯一注意到的是，对于我的应用程序，它说“[per-process-limit]”。这意味着什么吗？还有什么可能导致这次崩溃？如果重要的话，我正在使用 ARC。谢谢

Answer 1

嗯，MyApp有151118个常驻内存页，大约590MB(iOS下一个页4KB)。所以内存太大了。尝试使用 Instruments 中的分配工具运行并查看内存的去向。

编辑，实际回答问题:系统正在终止您的应用程序，因为它使用了太多内存。要修复崩溃，您需要减少内存使用量(在这种情况下非常显着)。我怀疑您有一个导致内存使用量激增的错误，因为根据您发布的日志，您的应用不太可能真正需要与它明显使用的内存一样多的内存。
