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
NSHomeDirectory()doesn't guarantee that it will return/var/mobile, especially from within sandboxed processes.- 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.
- App Store apps will return their sandbox data path from
NSHomeDirectory().
- See Cydia Substrate Pitfalls for additional guidelines regarding tweaks.
- You should consider the UDID deprecated like Apple has for some time, but if you need the device's UDID, use libMobileGestalt.dylib.
- If you need to use singletons, see singleton pattern for advice.
- If you need to respring from a tweak and you are targeting iOS 6 - 7, kill backboardd instead of SpringBoard. Killing SpringBoard has been known to cause some issues regarding the backlight. For iOS 8 and newer, if possible, use
SBSRelaunchActionor-[HBRespringController respring]from libcephei for a more appropriate way to respring. Simply killing the processes can destroy battery usage data (the feature since iOS 8).
