i am new in json parsing .I don't know how to send data to server[http://www.google.com/ig/calculator?] by use of textfield according to user input. And whatever result will come by server how will i display that data on my result label .
There is no official feature included in the SDK for parsing JSON. Have a look at the JSON Framework. Instructions are at the bottom of the page.
(Also just noticed that you asked something simliar an hour ago).

Recently i am making an app on facebook. So i have use facebook api. From api we got data from json parsing. Now in my app i am showing all update of user and his friends in table view. But problem is that when i get data from json parsing then application take so much time due to loading image in app. So i want that i show first text message and when view did load then upload images so that time will reduce. How do that i have no idea? So tell how i fix it?
I have use synchronous method to parse data from json. What approach i will use so i can consume less time?
I have sort my problem by seeing sample provided by Apple docs named as lazy table. In that i have edit like as in lazy table image upload on scroll to table so i remove that function. Now in my table when table load then image also load at that instant.Apple
I have been looking around for a while and not found anything useful, also not sure if I have worded the question in the clearest fashion so apologies
I have a section of an app I am building called 'Company News'. The company in question has a news page on their website which displays a title, an excerpt of text and a read more option.
At the minute in the iPhone application I just have a UIWebView which links to that URL, displays an error if no connection is available. However, if my user clicks a story to read the news obviously it opens up a new page, I want to avoid having to build in 'back' and 'forward' buttons and stay away from it looking like a browser within the app.
With that said, I am looking for a way to just extract that data from the website and just display it in my app as raw text. I am not particularly bothered about rich text formatting or anything fancy. I would just like the title and body of text.
Is this possible?
In essence, then, you are looking for an HTML parser.
Assuming the HTML you wish to parse has a predictable format, the approach I would take is to load the HTML via whatever URL loading system you want - e.g. NSURLConnection, ASIHTTPRequest, etc.
Then you will need to parse the raw HTML. I use XPath. It requires that you learn the syntax, but it should work.
For more details about how you might use XPath for parsing HTML, see the second response to this question. You will need to link to libxml2 in your project then use XPath to extract the nodes of interest.
Scraping web pages in this way is fragile, though, because it depends on the structure of a page you don't control and which could be changed unpredictably.
I'm using an NSXMLParser to read data out of a XML, but how can I make my iPhone App storing data into this specific XML.
The case is that I want to create an app to display available dates and one that administrates this dates, whether they are available or not (I'm using an UISwitch to handle this).
Thanks for your answers,

If you have small amount of data, you can save them in a plist.
See Property List Programming Guide
There's a github project that let's you create XML DOM objects. You can save your XML to your documents folder on the phone.

I am trying to implement a search tool on my iPhone, when i enter a text it will be send to the google for searching. and return the result.
I need to know how the text is given to the Google search engine and how the google is returning the result? Is it in the XML format or JSON.
I can then parse the result XML/JSON on my iPhone and want to display the results in my table view. Any idea? need Help...!
Thanks in advance,

either / or / any
One approach would be to use the google REST search API which returns JSON

The iPhone makes it really simple to snarf down an image from the web; you can turn a URL into a UIImage in one line of code. So I'd like to enable my app (an educational puzzle game... my first!) to download some random images to make it more interesting and dynamic.
I thought about using Kodak's image of the day RSS feed, but I'm having quite a time figuring out how to parse it. Rather than being a simple list of image URLs, it seems to reference a bunch of "jhtml" URLs, which run Javascript to display the images in your RSS reader. Is this intentionally obfuscated, or am I missing some basic step to parse this?
I also tried the Astronomy Picture of the Day, via this RSS feed, but it's just the original page's HTML stuffed into CDATA... ugh.
So I guess this is really two questions:
Is there a simple way to parse these feeds to actually get at the JPG URLs on the iPhone?
Is there a better source for "picture of the day" type images?
PS: I'm using NSXMLParser, which I learned to use here.
I would recommend going with something that has an API, perhaps the Flickr "Interestingness" feed:
http://www.flickr.com/services/api/flickr.interestingness.getList.html
There is an objective-C library written to help with accessing Flickr but not sure if this API call is included:
