推荐答案

UUID(通用唯一标识符) 基于每个应用程序.标识设备上的应用程序.只要用户没有完全删除应用程序，这个标识符就会在应用程序启动之间保持不变，并且至少可以让你在设备上使用特定应用程序识别同一用户.不幸的是，如果用户完全删除然后重新安装应用程序，那么 ID 就会改变.

UUID (Universally Unique IDentifier) Is on a per-app basis. identifies an app on a device. As long as the user doesn’t completely delete the app, then this identifier will persist between app launches, and at least let you identify the same user using a particular app on a device. Unfortunately, if the user completely deletes and then reinstalls the app then the ID will change.

UDID (Unique Device Identifier) A sequence of 40 hexadecimal characters that uniquely identify an ios device. This value can be retrieved through iTunes, or found using UIDevice -uniqueIdentifier. Derived from hardware details like MAC address.
