ios - 将 MP3 添加到应用程序主包而不更新

Question

我有一个用 Swift 编写的应用程序，类似于音板。目前我的应用程序主包中只有一堆 mp3。是否可以远程将更多 mp3 添加到应用程序主包中，然后更改代码中的变量以适应新的 mp3？我想要它，这样我就可以动态添加新的 mp3，而无需经历整个应用程序审核过程。理想情况下，用户第二天打开应用程序会发现已添加 15 个新 mp3，而无需下载更新。有这种可能吗？

You can’t write to the main bundle on iOS. Its contents are cryptographically signed as a part of the App Store submission process; modifying its contents would prevent the application from running.

File System Programming Guide :

• /AppName.app

  This is the bundle directory containing the app itself. Do not write anything to this directory. To prevent tampering, the bundle directory is signed at installation time. Writing to this directory changes the signature and prevents your app from launching again.

• /Documents/

  Use this directory to store critical user documents and app data files. Critical data is any data that cannot be recreated by your app, such as user-generated content. The contents of this directory can be made available to the user through file sharing. The contents of this directory are backed up by iTunes.

---

• /Library/

  This directory is the top-level directory for files that are not user data files. You typically put files in one of several standard subdirectories but you can also create custom subdirectories for files you want backed up but not exposed to the user. You should not use this directory for user data files. The contents of this directory (with the exception of the Caches subdirectory) are backed up by iTunes. For additional information about the Library directory, see “The Library Directory Stores App-Specific Files.”
