据我了解,Apple 应用程序更新将安装一个新的独立应用程序,而不是对现有应用程序应用补丁。

有谁知道这个过程的更多细节吗?这适用于用户的所有目录吗?任何文件夹(如私有(private)文档)都不会受到更新的影响。其他文件夹(例如文档等)怎么样?我希望找到一份描述该行为的文档,但到目前为止在网络上找不到。

我所说的更新是指:假设用户拥有版本 1.2 ...然后在可用时从应用程序服务器中提取数据。然后 1.3 上线到 App Store。用户更新到 1.3。

最佳答案

如下所述:iOS App Programming Guide ,关于更新您需要了解的是:

Files Saved During App Updates

When a user downloads an app update,iTunes installs the update in a new app directory. It then moves theuser’s data files from the old installation over to the new appdirectory before deleting the old installation. Files in the followingdirectories are guaranteed to be preserved during the update process:

  • Application_Home/Documents
  • Application_Home/Library

Although filesin other user directories may also be moved over, you should not relyon them being present after an update.
