从领域删除模型

我正在尝试从Realm中删除模型.我似乎有一种简单的方法可以在Java中使用

I am trying to remove a model from Realm. I appears there's a straightforward way to do it in Java with

realm.getSchema().remove(className)

除了从App中删除模型然后迁移数据或删除整个Realm文件之外，Swift 3中没有其他选项.

It doesn't appear there is an option in Swift 3 other than to remove the model from the App and then migrate the data, or delete the entire Realm file.

为澄清起见，当我打开Realm Browser时，我有三种模型

To clarify, when I open the Realm Browser I have three models

Dog 2 Person 4 Test 0

，我想通过代码删除Test模型.似乎也没有任何方法可以通过浏览器将其删除.

and I want to remove just the Test model via code. There doesn't appear to be any way to remove it via the Browser either.

也许我忽略了文档中的某些内容?

Perhaps I overlooked something in the docs?

推荐答案

不，您没有忽略文档中的任何内容.

No, you haven't overlooked anything in the docs.

在不触发迁移的情况下，不可能在Objective-C/Swift SDK中修改Realm文件的架构.在这种情况下，您可以使用 Migration.deleteData(forType:) 从领域删除对象架构.

It is not possible to modify the schema of a Realm file in the Objective-C/Swift SDKs without triggering a migration. In which case, you can use Migration.deleteData(forType:) to delete the object schema from the Realm.

此外，如果您想首先确保没有将Test添加到您的Realm文件中，则可以明确定义在您的Realm配置中.

Additionally, if you want to explicitly ensure that Test isn't added to your Realm file in the first place, you can explicitly define that in your Realm configuration.
