我尝试通过创建新的模型版本并向此模型添加新属性来尝试迁移核心数据模型。
当我尝试调用addPersistentStoreWithType时,得到此错误:

我认为原因是所有以XMPP开头的类都来自第三方库,并且在新的源模型中找不到这些类。
我不知道如何迁移第三方模型,我试图从de数据库中删除这些类,但它们并不存在于同一个数据库中......
我发现出了什么问题,我在managedObjectModel中调用了这个方法:
managedObjectModel = [NSManagedObjectModel mergedModelFromBundles:nil];
但我需要像这样创建de managedObjectModel:
NSString *path = [[NSBundle mainBundle] pathForResource:@"name" ofType:@"momd"];
NSURL *momURL = [NSURL fileURLWithPath:path];
managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:momURL];
问题在于,现在我已经将这些实体混合了...我如何将它们分开?
