iPhone：20 分钟后 MapView 中的应用程序崩溃
我正在开发一个跟踪用户位置的应用程序。大约 20 分钟后，应用程序似乎总是崩溃，我不知道为什么。设备日志显示：

看起来我正在尝试发布已经发布的内容，但是什么？！我启用了 NSZombie，但它似乎没有帮助。
它曾经有效，我最近更新了我的课程以使用 self.对于我合成的任何内容，这可能是问题所在吗？
编辑：我更新了错误。它似乎列出了每行的行号，但它们似乎并不能帮助找到问题。
I am working on an app that tracks a users location. After about 20 minutes it seems that the app always crashes, and I am not sure why. Device logs show:

Looks like I am trying to release something that has already been released, but what?! I have NSZombie enabled, and it does not seem to help.
It used to work, and I recently updated my class to use self. for anything that I synthesized, could this be the issue?
EDIT: I updated the error. It seems to be listing the line numbers for each line, but they do not seem to be helping to find the issue.

您在设备上运行时是否启用了 NSZombie？如果是这样，您可能内存不足。如您所知，NSZombie 保留已释放的对象，以便您可以检测到双重释放。
不过，您可能确实存在一些记忆问题。静态分析仪会向您显示什么吗？ （shift-命令-A）。
Do you have NSZombie enabled while you're running on the device? If so chances are you are running out of memory. As you know, NSZombie keeps released objects around so you can detect a double release.
Chances are you do have some memory issues though. Does the static analyzer show you anything? (shift-command-A).
将位置管理器委托设置为 nil 然后释放它为我修复了崩溃。
Setting the location manager delegate to nil AND THEN releasing it fixed the crash for me.
