iphone – cocoa错误134100再次 – (用于打开的模型与用于创建的模型不兼容…)

我在这里发布了这个问题,但总是,答案是模型已经改变,重置模拟器,删除商店.

我也收到了这个错误,但是,这是一个新的应用程序.我没有添加/更改实体或属性.

我删除了商店,我重置了模拟器,但我得到了相同的结果.

这是商店代码..这个问题还有其他原因吗？

- (NSManagedObjectModel *)managedObjectModel {
   //  NSLog(@"%s", __FUNCTION__);
    if (managedObjectModel_ != nil) {
        return managedObjectModel_;
    }

    NSString *modelPath = [[NSBundle mainBundle] pathForResource:@"Lexicon" ofType:@"momd"];
    NSURL *modelURL = [NSURL fileURLWithPath:modelPath];
    managedObjectModel_ = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];    
    return managedObjectModel_;
}

/**
 Returns the persistent store coordinator for the application.
 If the coordinator doesn't already exist, it is created and the application's store added to it.
 */
- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {

    if (persistentStoreCoordinator_ != nil) {
        return persistentStoreCoordinator_;
    }

    NSURL *storeURL = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"dict.sqlite"]];

    NSError *error = nil;
    persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
    if (![persistentStoreCoordinator_ addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:nil error:&error]) {

        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        abort();
    }    

    return persistentStoreCoordinator_;
}

这是控制台喷出的：

最佳答案 事实证明,sqlite DB存储是错误构建的.因此,在这种情况下,消息相当准确.

上面的问题是真的.数据库没有反映模型.

解决方案是让Core Data从模型中创建空数据库,然后让Core Data自行导入数据.

我首先将我的sqlite数据库导出到sql,调用文件db.sql(imaginative！).我只导出数据表和主键表,而不是元数据表.我使用了一个名为SQLiteManager的应用程序.您也可以在命令行执行此操作.

除处理持久存储控制器外,所有代码都是库存.

该代码如下：

- (NSPersistentStoreCoordinator *)persistentStoreCoordinator {

    if (persistentStoreCoordinator_ != nil) {
        return persistentStoreCoordinator_;
    }


    NSString *storePath = [[self applicationDocumentsDirectory] stringByAppendingPathComponent:@"db.sql"];

    // set up the backing store
    NSFileManager *fileManager = [NSFileManager defaultManager];
    // If the expected store doesn't exist, copy the default store.
    if (![fileManager fileExistsAtPath:storePath]) {
        NSString *defaultStorePath = [[NSBundle mainBundle] pathForResource:@"dict" ofType:@"sqlite"];
        if (defaultStorePath) {
            [fileManager copyItemAtPath:defaultStorePath toPath:storePath error:NULL];
        }
    }

    NSURL *storeURL = [NSURL fileURLWithPath:storePath];

    NSError *error = nil;
    persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]];
    if (![persistentStoreCoordinator_ addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:nil error:&error]) {

        NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
        abort();
    }    

    return persistentStoreCoordinator_;
}

我希望这有帮助..它似乎对我有用..
