, reason=Can't find model for source store}'

它说找不到源商店的型号？这是什么意思？

代码是：

- (void)createPersistentStoreCoordinator {
    NSURL *storeUrl = [NSURL fileURLWithPath:self.pathToStoreFile];

    NSError *error;
    _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:_managedObjectModel];

    // Allow inferred migration from the original version of the application.
    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                             [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption,
                             [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];

    if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) {
        if (self.delegate != nil && [self.delegate respondsToSelector:@selector(managedObjectStore:didFailToCreatePersistentStoreCoordinatorWithError:)]) {
            [self.delegate managedObjectStore:self didFailToCreatePersistentStoreCoordinatorWithError:error];
        } else {
            NSAssert(NO, @"Managed object store failed to create persistent store coordinator: %@", error); //fails right here
        }
    }
}

我注意到你正在使用 RestKit，我以前也遇到过这个问题，并通过删除我的 SqlLite 数据库解决了它。对我来说，这是当我添加新关系并且数据库不喜欢新属性时。

注意：这在开发中效果很好，但在生产中，您通常需要执行核心数据迁移，因为用户不希望他们的数据丢失（取决于您的应用程序）。
