    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 important so 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.

    Thanks in advance

    Aloha nickyu,

    I'm just starting out myself with Obj-C and Xcode. As such, I haven't attempted an iPhone app, but one thing I do with the apps I've written thus far is to use the Console and insert NSLog statements to indicate success (or lack thereof) of certain parts of my code. I don't know if that option is available to you, but if so, you could use the log to indicate whether or not the data has been saved.
