ios - (NSFetchedResultsController) : couldn't read cache file to update store info timestamps

我将我的项目升级到Xcode8。现在,我收到了Xcode8和iOS10组合的错误日志。在下面的代码中将cacheName设置为nil似乎可以解决这个问题。NSFetchedResultsController*frc=[[NSFetchedResultsControlleralloc]initWithFetchRequest:fetchRequestmanagedObjectContext:self.managedObjectContextsectionNameKeyPath:NULLcacheName:@"myCache"];我应该怎么做才能摆脱这个错误日志并在我的FRC中使用缓存?
