Use the following guidelines to avoid your package or app being fragile and to increase the chances of it being accepted by a community host.
Applications and Tweaks
- Avoid referring to /var/mobile directly - use NSHomeDirectory() if your code is running as mobile!
- If your code is running as root, use extra caution when writing files that mobile can access - you might break the file's access permissions.
- See MobileSubstrate Pitfalls for additional guidelines regarding tweaks.
- If you need the device's UDID, use LibMobileGestalt.dylib.
- If you need to use singletons, see singleton pattern for advice.
Packages
- Do not create mobile-owned files and/or directories in your package. Stay out of mobile's home directory!
- All package files are installed as root. Your software should create any required files or directories at runtime.
- This is doubly important for preferences. A user's preferences do not belong in a package: if preferences are stored in the package, they will be overwritten when you release an update, and deleted when the user uninstalls your software (even temporarily!)
- Do not use postinst/preinst/extrainst_ for file management purposes!
- Do not store in the package files or directories that your software could create.
- Do not enforce permissions that your package should contain. dpkg uses an expressive packaging format that has support for permissions, ownership, and links. Use that support!
- Make sure your package doesn't include hidden .DS_Store, ._*, or thumbs.db files.
