本文介绍了一个关于NSFetchedResultsController缓存错误的问题及其解决方案。当非法修改了NSFetchedResultsController的相关属性且未禁用缓存时，可能会遇到致命错误。文中提供了一段示例代码来解决这个问题。

FATAL ERROR: The persistent cache of section information does not match the current configuration.  You have illegally mutated the NSFetchedResultsController's fetch request, its predicate, or its sort descriptor without either disabling caching or using +deleteCacheWithName:

        NSError *error = nil;
        if (![self.fetchedResultsController performFetch:&error]) {
            // handle the error...
        }

上面加一段代码就可以了

[NSFetchedResultsController deleteCacheWithName:nil];
