Help/Support who and when will create preference bundle file in /var/mobile/Library/Preferences/tweakid.plist

CookieFJ · December 19, 2018

Thanks for the preference template.

Just noted that the initialization not correct as I expected.

value not same as in Root.plist. looks like random value.

in %ctor, tried to fetch the value from /var/mobile/Library/Preferences/tweakid.plist, but failed since I can't find the plist file in Filza.

After do some setting in tweak setting, the plist file was created. Then the values are synced up with setting.

Question: who and when will create preference bundle file?

Thanks.

/var/mobile/Library/Preferences/xxxxxxx.plist is create when the "setting > yourhack" made changes

Toggle switch or enter string.

the plist will auto generate when you change something inside Setting.

inside the plist you set.

com.youcompany.tweakprefs

this need to change to your key.

com.abcde.appname

so your plist should auto named:

com.abcde.appname.plist

Thank you for your answer. I got it.

May I have further questions:

Preference not initialize as Root.plist expected. For example, nRecent slider indicates 2 but not default 3. What will cause this?

Update: looks it is set to previous value before uninstalled. So, there should be somewhere to save tweak's preference besides /var/mobile/Library/Preferences/xxxxxxx.plist or Root.plist. I made sure these 2 files do not exist before I re-install my tweak.
