I have created one app in iOS5.
I want to store and retrive data on web server.
For that I want to use JSON parser.
I have used demo given by ray wenderlich for ios4. I heard that for ios 5.Some ready made frameworks are there.So can anybody having any idea regarding this?
I am using sqlite for data storage.
Please Help.
You may want to refer to SBJSON Framework which is frequently used for objective-C, I have used this framework in may of my iOS Apps.
You may get a reference about it from these links:
https://github.com/stig/json-framework
http://stig.github.com/json-framework/
Example Code: Also here is an example on, How to parse JSON with SBJSON Parser:

Here is how you need to configure SBJSON into your app:

Hope this helps you.
Since you are a RayWenderlich Fan, They have a pretty amazing tutorial out there on the new iOS5 JSON Parser
I suggest you to used Twitter Framework for json, it's really easy to learn json, and you just have to used api of twitter, here is the all api available for twitter,

I want to retrieve data from server using HTTP POST method for my iphone app.I don't have any idea about implementing it.
Please help me.
Thanks in advance
The simplest way to achieve this is to use the framework ASIHTTPRequest. Take a look in the tutorial: http://allseeing-i.com/ASIHTTPRequest/How-to-use
start with NSURLRequest and related sample code.
I am making an iphone application.
I am a newb.
I want to fetch the data from my website. What should i do to implement this?
What needs to be done?
Help me please
Thanks
Any tutorials would be of great help.
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

Hope this helps you
You will be using the NSURLConnection, NSURLRequest and NSURL classes here is an example from Apple; http://developer.apple.com/library/mac/ipad/#documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html
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.
Chapter 10 of James Kennard, Mastering Joomla! 1.5 : APIs and Webservices contains 8 pages about XML-RPC.
For real-live examples, search the Joomla! Extension Directory.
http://extensions.joomla.org/extensions/search/xml-rpc
Here is another one to kick-start http://www.slideshare.net/coolparth/rest-api-for-joomla
For the server side, I suggest using a web service to send the data to your client.
ORIGINAL AUTHOR'S REVISION:
The September issue of Linux Journal has an excellent article on writing mobile apps that work for Android AND iPhone/iPad using free tools and frameworks. Here is a link to the article online:
Developing Portable Mobile Web Applications
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).
I'm quite new in iPhone development and I need to develop an app.
I must get mp3 data from a web server, which provides a simple saving the mp3 in my app document or folder
and use it in an application, which should also dislpay a table with rows like:
song1
song2
song3
But at present I don't know at all how to get this web page, parse it and store into an array in the application.
Please do you have any suggestion / hint / sample code ?
Thank you in advance,
There is a tutorial on the apple developer site on how to make a http request and receive data here. Should get you going on how to fetch the web page.
For parsing you can use the NSScanner or a XML/HTML parser library like TouchXML depending on your needs.
I used web services to communicate with web server, the following tutorial helped me a lot.
http://icodeblog.com/2008/11/03/iphone-programming-tutorial-intro-to-soap-web-services/
I was able to send and retrieve binary content using web service but I had to encode it first to be able to send it through Soap request and decode back Soap Response.
Hope that can help you,
Is there a class to parse JSON from a server in the iOS SDK? (similar to NSXML for XML and by extension RSS.)
As of iOS5 JSON is been natively supported, no need for 3rd party frameworks.
This is supported by the NSJSONSerialization Class!
Updated answer for iOS 5:
JSON support is now native to iOS with NSJSONSerialization, but in terms of performance, it pales in comparison to JSONKit, as John Englehart stated in the JSONKit README:
UPDATE: (2011/12/18) The benchmarks below were performed before Apples NSJSONSerialization was available (as of Mac OS X 10.7 and iOS 5). The obvious question is: Which is faster, NSJSONSerialization or JSONKit? According to this site, JSONKit is faster than NSJSONSerialization. Some quick "back of the envelope" calculations using the numbers reported, JSONKit appears to be approximately 25% to 40% faster than NSJSONSerialization, which is pretty significant.
Here's a blog post which delves into more specific benchmarks: JSON Libraries for iOS Comparison
There are several JSON libraries for the iPhone listed in this thread:
https://stackoverflow.com/questions/286087/best-json-library-to-use-when-developing-an-iphone-application
NextiveJson is supposed to be quite a fast lib for iOS JSON
NextiveJson
Regarding JSONKit benchmarks, for the current moment and iOS version it's not so fast. After creating test application for testing speed NSJSONSerialization is faster but not so fast as custom implementation OKJSONParser
I have been here before, asking for a mapping library that could store objects in a database. Some one told me about the Core Data Framework. I have read a bit about it and I kindda understand it.
I have created some "test Core data projects", where I have worked with simple problems and models ala Person and Group. But now I want to experiment with implementing Core Data to one of my small iPhone apps. How do I do this? Subclassing from NSManagedObject and make a Managed Object Model?
I know that there is more to it, but I havent found anything on google og apples site. Maybe Im looking in wrong direction while googling and searching.
A link to an article/tutorial explaining me how to add Core Data to my project would make my day.
There's a tutorial on iPhone developer site here. And there are several sample codes with Core Data as well. These should get you started.
The book, More iPhone 3 Development begins with a great tutorial demonstrating how to use Core Data. I've found it incredibly helpful.
Here is a basic CoreData screencast that, while not specifically for the iPhone gives a decent introduction to CoreData concepts.
