Answer 1

领域 .lock 文件是一个仅由领域使用的幕后文件。在使用捆绑领域时，您永远不需要直接使用该文件或将其捆绑。所有需要的领域文件本身，拖入 XCode 项目。

以下是访问名为 MyBundledData.realm 的捆绑领域的方法：

let config = Realm.Configuration(
    // Get the URL to the bundled file
    fileURL: Bundle.main.url(forResource: "MyBundledData", withExtension: "realm"),
    // Open the file in read-only mode as application bundles are not writeable
    readOnly: true)

// Open the Realm with the configuration
let realm = try! Realm(configuration: config)

这应该是所有需要的

尝试在父目录中添加 NSFileProtectionNone 让境界=尝试！境界()

// 获取我们的 Realm 文件的父目录 let folderPath = realm.configuration.fileURL!.deletingLastPathComponent().path

// 禁用该目录的文件保护尝试！ FileManager.default.setAttributes([FileAttributeKey(rawValue: NSFileProtectionKey): NSFileProtectionNone], ofItemAtPath: 文件夹路径)
