Question

首先，我不知道导致问题的原因，我只能在设备硬件重启后重现它。之后该应用程序很好。

我使用MagicalRecords lib。
＆＃34; [MagicalRecordHelpers setupAutoMigratingCoreDataStack]＆＃34;在内部调用＆＃34;应用程序： didFinishLaunchingWithOptions：＆＃34 ;.
经过一些内部方法调用和它会冻结10-15秒。

这是来自控制台的日志，您可以在其中查看来电的详细信息和时间。我只是注意到它被一些奇怪的（对我来说）低级别的电话冻结了。

我真的不知道用户是否面临这个问题。但如果这样做可能会在许多人开始时崩溃。

我知道这个问题难以分析，但如果您至少有任何相关的想法或想法，请分享。另外，请询问任何细节。

提前感谢。
