Question

I’m absolutely new to iOS App development (I haven’t actually started yet, still in a design phase).
The task that I have to accomplish with my app is to download a zip from somewhere, extract anywere to local storage and display its content (html pages with javascript) in a embed webkit widget.

The questions are:
1) Will my app have access to any folder of my iPad storage memory?
2) Will my app’s embedded Webkit widget be able to display local html pages (like file:///somewhere/over/the/rainbow.html ?
3) WIll that local page be able to use Ajax method (over httpxmlrequest) to dynamically load external scripts or xml (also locally stored – ie ./something.xml)?

Thank in advance for any help!

1. No it can’t access any file. Apps are sandboxed on iOS. You can only access the app bundle’s content and documents folder (a writable area unique to your app).
2. Yes – provided said content is in the areas mentioned in (1). This is how Phonegap-based apps work.
3. Yes – they can. We’ve done exactly this extensively in several of our apps.
