nickyu Posted June 4, 2008 Share Posted June 4, 2008 I am new to obj-c programming/iphone, so I am probably missing something. I am making a simple xml feed reader, which has AppDelegate, ListViewController, DetailViewController (other parts are not left out for simplicity). - AppDelegate gets the XML from a URL, Parse the content into an NSMutableArray. WriteToFile. - ListViewController recover the array using dataWithContentOfFile, populate the list view - When use click on a item, then it brings to detail view. DetailViewController recover the array using dataWithContentOfFile, get the selected Data, display. What I could not figure out is that: the data can not be recovered from ListViewController, or DetailViewController, or maybe it didn't get saved at the first place. Since it is running with iphone simulator, I don't know if there is anyway to check if the file being created at the first place.
