iphone - Is there a way to persist application data between application installs and uninstalls in iOS -


i developing application needs perform expensive calculations @ start up. so, first time application runs, application calculations , store result in file.

if user decides uninstall application , re-install later, calculations have done again , avoid re-calculate. notice not talking updates of application uninstall / re-install.

i wondering if there way persist data accessible application can survive uninstalls.

the solution can inside device (using kind of files / preferences / ...) or based in server. example, possible solution send device id result server , store there, device id has been deprecated in ios 5, not valid solution anymore.

thank answers.

you don't how data, following options:

  • icloud
  • keychain
  • dropbox

the "universal" option, devices have , cannot disabled, keychain though limited amount of space can use.

personally, nothing. if user deletes app think it's fair game have recompute stuff on reinstallation.
