nsuserdefaults intitial setup 2 answers

i utilize nsuserdefaults store app settings.

i need set default value settings.

so added isappfirstlaunch value defaults , set needed default(initial) values settings in on app first launch.

but add together new settings. in case isappfirstlaunch false , can't set default value have delete app , install againg.

so question is: how set new settings default values?.

as unserstand if app in appstore

[[[nsbundle mainbundle] infodictionary]objectforkey:@"cfbundleversion"]];

than can store app version in defaults , check if version changed set new defaults.

but debugging? should delete app clean defualts?

you can check whether setting exists (if different null) , if doesn't exist, set default value.

you can add together code app delegate's applicationdidfinishlaunching method checks if setting null , so, sets it. every setting in app.
