If you want to connect to an external data source and then somehow process the data you have receiver, I’d look into the NSURLConnection class. It allows for asynchronous file downloads and you can then be notified about the progress via several useful delegate methods (didReceiveData, didFailWithError, connectionDidFinishLoading). Once you’re data have been downloaded, you can process it however you need to.

Thanks for your great tutorial.

When I check in 4.0 Simulator, First tab goes well to the detail view, but after going back to the table view, the app turns off.

How can I solve this problem?

Best Regard

Great Tutorial, Very helpful.
But. There is always a but, if we make things custom, sorry about it.
i looking for a answer within you tutorial to load the testdata.plist for a URL.
I Know its possible, with initWithContentsOfURL: but i have really not idea how to use this in you tutorial.
a helping hand, with some implemented code examples, where to use this method would be very very nice.
i’m looking forward to see your reaction.

Best Regard
Robin.

Hmm, I tried to recreate the crash but was unable to no matter where I tap. Can you share exactly what you’re doing to make it crash?

Hmm, I can’t replicate this on my computer. What SDK version do you use? I haven’t looked at the code in a while but I would assume dao isn’t initialized when libraryCount is being called on it. I’ll check it out and see what’s going on. Thanks for the feedback.

This is a great tutorial. But I’m having a problem with it. (I’ve just done the first portion – not the detail controller section)
It is throwing an NS Exception.
It seems to be caused by the numberOfRowsInSection method. If I have that method return a fixed integer, then the app works correctly. When I used the code:

return [dao libraryCount];

It locks up. Any ideas?

You need to handle JSON yourself, there are no built-in APIs to handle it (as of yet). There are few open-source libraries out there that do a lot of parsing for you. The most popular is JSON Framework (on Google code).
