使用核心数据重新打开应用程序后 EXC_BAD_ACCESS

发布于 2025-01-05 16:27:16 字数 1974 浏览 4 评论 0原文

我有一个使用核心数据的应用程序。我能够在第一次在模拟器中构建和运行应用程序时保存和获取数据，但是，当我关闭应用程序、在模拟器中终止它并重新运行它时，它会崩溃并显示 EXC_BAD_ACCESS< /code> main 内部。

如果我在模拟器上卸载应用程序并再次运行它，一切都会再次正常工作，直到我关闭应用程序并在发生同样的事情时再次打开它。

在将核心数据添加到我的应用程序之前从未发生过这种情况，因此我假设它与此有关。下面是崩溃后的回溯。

我是否有可能在杀死应用程序后没有正确“关闭”我的持久存储？感谢任何帮助，谢谢。

原文

I have an app that uses Core Data. I'm able to save and fetch data upon the first time my app builds and runs in the simulator, however, when I close the app, kill it in the simulator, and re-run it, it crashes with EXC_BAD_ACCESS inside of main.

If I uninstall the app on the simulator and run it again, every thing works fine again, until I close the app and open it again when the same thing happens.

This never used to happen before adding Core Data to my app so I'm assuming it has something to do with that. Below is a backtrace after the crash.

Is it possible I'm not properly "closing" my persistent store after killing the app?
Any help is appreciated, Thanks.
