i'm writing app blog. posts parsed xmlparser.

how can store posts on iphone don't need downloaded , parsed every time app started , more important app not stay blank if there no connection internet.

i know core data have use. how? thank help.

to resolve storage issue , offline availability of service can use
1. core data
2. sqlite database.

  • so after parsing feeds, should insert them database. , when appear fetch records database , reload in tableview.
  • on other hand when internet connection available make network call fetch new records server , insert/save them database , reload table again.
