我们已经向AppStore发布了一个应用程序,在更新后,它在尝试登录后崩溃了。我们在很大程度上依赖于CoreData数据库,我们认为这是崩溃的原因。然而,我无法从设备中获取任何有价值的信息,只是一个包含一些线程信息的崩溃日志。这是它的外观:

还有其他机会可以从这种情况中获得更多信息吗?如何将其插入XCode并可能跟踪崩溃,或者只能在事后进行?

最重要的是,您认为导致崩溃的原因是什么?

我们的问题与Core Data轻量级迁移有关 - 我们使用名为Magical Record的库来处理我们的Core Data提取并更新解决问题。此外,这篇文章非常有用 - http://pablin.org/2013/05/24/problems-with-core-data-migration-manager-and-journal-mode-wal
