Question

我是 iPhone 应用程序开发新手，当我在设备中运行我的应用程序时，应用程序崩溃并在管理器中提供以下登录

任何人都可以帮助如何跟踪日志报告吗？

Answer 1

这不是应用程序崩溃，而是应用程序终止:iOS 有一种称为 Jetsam(或正式称为内存状态)的机制，当最大进程(就内存而言)时，该机制会“抛弃”(即抛出)最大的进程(就内存而言)。物理内存不足。这是一个必要的措施，因为iOS没有swap。在由 jetsam 生成的日志中，您可以看到所有事件进程和 BJS(已被丢弃)的列表。格式为:

Incident Identifier: Automatically generated GUID for Apple
CrashReporter Key:   Hash, probably of GUID
Hardware Model:      i-Device stepping (4,1 is 4th gen iPod in your case)
OS Version:          Version of iOS
Kernel Version:      Kernel version, as per uname -a
Date:                ... figure this one out
Time since snapshot: How much time has passed - the snapshot may be "dated"

Free pages:        How many free pages of RAM remain. Page = 4k
Wired pages:       How many resident pages
Purgeable pages:   How many pages MAY be freed, if all else fails
Largest process:   The culprit

 Processes
     Name                 UUID                    Count resident pages
         BJS <312d3dae46e433f9982c26738e40060b>   36928 (jettisoned) (active)

表格，根据列标题，其中(抛弃)意味着jetsam杀了你。 (活跃)意味着您是前台应用程序。

希望这有帮助，(如果没有帮助 - 发表评论或直接问我)
