ios - iOS 上/tmp/文件夹中的照片什么时候过期

Question

在 iOS App 上使用相机时，iPhone 会将临时照片保存到此文件夹:

file:///var/mobile/Containers/Data/Application/3823983289389/tmp/cdv_photo_138.jpg

这些什么时候过期？ iOS 会在一段时间后删除这些内容吗？它有多长，或者您能否以编程方式调整它？

Answer 1

您无法控制 tmp/ 文件夹中文件的生命周期。您所知道的是，操作系统可能会在您的应用程序未运行时随时清除此类文件。

来自documentation :

Put temporary data in the tmp/ directory. Temporary data comprises any data that you do not need to persist for an extended period of time. Remember to delete those files when you are done with them so that they do not continue to consume space on the user’s device. The system will periodically purge these files when your app is not running; therefore, you cannot rely on these files persisting after your app terminates.
