How to retrieve data from a website into an iPhone app

Question

I am making an iPhone application. I am a beginner.

I want to fetch the data from my website. What should I do to implement this?

Answer 1

If your problem is getting data from website to iphone then you can just use JSON Parsing to get data.

Just you have to pass all the data as JSON string in iPhone from your website. And then parse the data once received into your iPhone.

Here you can refer to this link:

Answer 2

Previous answers suggest using NSURLConnection, but I find it to be a bit cumbersome to use on its own. I suggest using something that wraps NSURLConnection (or CFNetwork). Some examples: ASIHTTPRequest (CFNetwork-based), httpriot and Seriously (NSURLConnection/block-based).

Answer 3

For the server side, I suggest using a web service to send the data to your client.

Expose your data from your site as WebService, XML, JSON etc. Consume that using iPhone app. Which language is being used your site?depending on that some sample could be provided.
