ipad programming guidance

I'm just at the startup level in ipad/iphone programming. There is a project in my mind, but I need some guidance on key points:

fundemental requirements: 1)user interface and interaction like wired magazine app(playing movies on page,etc) 2)acc开发者_如何转开发essing the timeuser spent on pages and videos more: -accessing another application's data (and let's say that application can give permission, if there is so)

Maybe these are just easy things to figure out, but if you could point me where to look I would be pleased.

PS: I have more than 10+ top seller ebooks on ipad/ios/iphone programming and I'm started to reading them. To be clear, names of these concepts (in what way I should research accessing the time user spent on a page- I did try on google on my own words but could not get the desired result)or some material pointing the issues really ease my way.

The UI portion of your question should be pretty easy to get to, it will just take learning a lot of the Cocoa Touch library, probably even a bit of Core Foundation.

There are two books I highly recommend:

• Programming iOS 4
• iPhone Programming: Big Nerd Ranch

I strongly recommend Programming iOS 4, primarily because it has been updated for XCode 4.

To answer your other question: to the best of my knowledge, you are not allowed to access other application's data due to sandboxing. You can, however, share data between your own apps if they share the same App ID.

First, as to the question on sharing data between apps. You can pass data between apps - basically launching one app from another and passing arguments. This can go both ways. If this is what you want, I'll share more on that.

As to learning, I recommend devouring Apple's documents, their samples, and Stackoverflow. Most of the iPhone development books you come across on development will be useful.
