In my universal iOS application I create a folder structure that is saved in a plist file. It is built like this:

  • [Array] Root
    • [Dictionary] Item 0
      • [String] Title
      • [Array] Children
        • [Dictionary] Item 0
        • [Dictionary] Item 1
    • [Dictionary] Item 1
      • [String] Title
      • [Array] Children
        • [Dictionary] Item 0
        • [Dictionary] Item 1
        • [Dictionary] Item 2
        • [Dictionary] Item 3
    • [Dictionary] Item 2
      • [String] Title
      • [Array] Children

With this structure I navigate through the folders. The contents of the current data source (always an array) are displayed in a table view. Now it may be that some data is changed. Therefore I want to refresh my table structure and the data to fill in. If this is done in the root folder there is no problem, but if I try it in any of the subfolders I can only refresh the current array. So if I navigate back to an upper level of the structure still the old data is used.

What would be good practice to update all of my data, but still stay in the currently selected folder (only if it still exists)?

Thanks in advance

    1, You have a class method which is for updating the plist like this: [MyMethod updatePlist];

    2, You have a parent view controller which has viewWillAppear or viewDidAppear methods. In there, you call [MyMethod updatePlist].

    3, All your viewController inherit parent view controller.

    So every time when you load a new view controller view, it always updated the plist. If necessary, you can add processing stuff to show loading.

    Is that helpful?
