I am working on iphone networking application.. I am using asihttp , a wrapper of the CFnetwork framework. http://allseeing-i.com/ASIHTTPRequest/
I want to build a server that sends some data on request from the client... I want this for the sole purpose of testing the application i write and understanding the networking more deeply..
Any help is appreciated
Thank you
Seems like the most straight forward solution is to setup an Apache HTTPD server and just put a static document at the location you want your data to come from.
The two most simple approaches that come to mind:
Enable Web Sharing on your Mac. You can then access the documents in your Sites directory inside your home directory. The Sharing preference pane will tell you the exact URL.
If static content is not enough, write a little Python web server to serve content. Python comes with standard HTTP Server modules. You can get stuff going with like half a dozen of lines of code.

I want to create an application in which i want a login logout authentication from the database file that can be handled by web services. This application should always need to be connected with the internet and after login i need to upload images and also give there views about the image and i am not getting any idea how start work on that can anyone help me.... I want to use this application some sort similar like facebook.
There is also a problem that which type of application i create native or web or else. Please help me to start this application.....
Try setting up a server that can handle the requests from your app. Your app can then request content or upload content to the server using NSURLRequest. For further reading refer http://developer.apple.com/library/ios/#documentation/Cocoa/Conceptual/URLLoadingSystem/Concepts/URLOverview.html
I think you are asking the wrong question. What web development language do you know to help you accomplish this? There are many different ways to go, like open source as opposed to paid, which services best handle your specific needs, like Ruby or PHP, which RDBMS to use, etc. If you don't know any programming, then it is going to be a long road. Your first step should be taking what you already know and branching from there, learning what you need to know. In your case, you'll need to learn server side scripting, connect it with a database, how to set up a server to put it all in, as well as client side development like javascript to go with the html.
Im new to website development and design so apologize in advance if the question is redundant.
I have a program where a client, using a URL string fetches a XML file from a webserver. This would be no problem right if it were a simple URL with no security or no CMS (like Joomla) involved: Just put the exact URL string and the client gets the file from the web server, done.
But, how would the process work if the URL is on my site hosted on GoDaddy and using a Joomla CMS?
Im trying to understand how the same process of fetching a file works on a hosted server using a CMS. Since I just made the transition from my site being on my school's servers to having a Joomla website Im hosting on goDaddy.
I mean where would I put the file if I also want the file to be accessible only if the client authenticates itself first. Just to be on the safe side. I mean is this how normally things work in mobile apps? I have a client program thats a iPhone app and within the app I have a XML file which is used as a data source for my UITavleView, but I want to check some URL to see if an updated version of the XML file exists. My app side programming is mostly done, now Im trying to learn the server side things I need to do to make this process happen with Joomla and my own hosted site
I donot understand how would the process work in that case. I mean, what are the things I would need to do on the server side to and the client side to make this possible?
Please help me understand or if you could point me to some links where these steps are illustrated...or if you could give me some Google key words I can search for to learn about this process.
thanks a lot
The fact that you have a CMS does not generally change how you access a file within the file structure of your domain unless the CMS protects certain directories. In this case, Joomla does not so you can directly access any file you wish. Depending on the sensitivity of the information you are trying to retrieve, you can protect the directory through your domain management panel. If it's not particularly sensitive, the authentication can be done by the app since the URL you are accessing can be easily hidden from the user.
It seems like that would be the simplest solution since the app will have access to user information by nature of where it resides.
I'm writing a very simple iPhone app, basically a dropbox where people can submit ideas and then view what's in the dropbox. I need to write a server that will respond to my iPhone's (HTTP?) requests. Are there any good tutorials on the web that will show me how to do this? Thanks.
Well it really depends on what kind of platform are you trying to write your server.
If it's going to be linux, apache, mysql and PHP (LAPM) then probably this question would answer some of your questions: Serving a json file for IPHONE app
Also this one might be helpful: http://www.sencha.com/learn/Tutorial:Creating_JSON_Data_in_PHP
You could server your data in various formats: binary, XML, JSON, etc. However if I were you i would definitely choose JSON ...
You also can use ruby, .net or anything else for building your web server, however probably php is going to be the one with the most examples.
Hope this helps.
For communicating with the server take a look at ASIHttpRequest, which has some good documentation and example code included http://allseeing-i.com/ASIHTTPRequest/How-to-use
i recomment using the ASIHttpRequest Classes.
On the serverside just use a simple JSON API and probably oAuth or HTTP Authentication to submit and receive Data from a Database.
Do I need to implement my own sync methods in order to make an offline web app (html+css+js) stay up to date with changes made on the server (and viceversa)? I'm using MySQL on the server side.
I read Two-way sync between iPhone application and web application with some pointers but I think they're talking about native applications when they mention CFUUIDCreate and I wander if this is possible for the Web.
Does someone have some code to share or maybe can point me in the right direction?
Thank you!
P.S.: I hope my english is not that rusty ;)
To store static contents on the client-side, as Jethro Larson said, the Application Cache Manifest is the way to go to cache the static contents of your website (HTML, CSS, JS and images).
To handle dynamically generated contents offline, you can use javascript templates. There are several solutions for this.
To sync the two databases, there is a project called persistence.js (persistencejs.org) which is a javascript library which offers a unique API to work with WebSQL databases, Local Storage, etc. They have a plugin for this library called persistence.sync (persistencejs.org/plugin/sync) which syncs the remote database with the server's one. It consists of POST and GET requests to a specific url that you can configure (for example yourapp.dev/sync). They have an example back-end written in node.js and here is one for Rails. It's simple to understand and persistence.sync is well documented.
Look at the offline cache:

http://www.google.com/search?q=offline+cache+html5
http://www.slideshare.net/search/slideshow?q=offline+cache
I'm in the middle of working on my first native application with networking and I have a question regarding the best way for interacting with remote storage. In a perfect world I'd like to do the following.
Prompt the user for login information from the iPhone.
Verify the users credentials and connect to a MYSQL database hosted by myself.
Parse MYSQL data into a table view.
Allow the user to add or update information in the database.
I've read some similar questions posted, maybe something's lost in translation, but the two most common means I've come across are.
Create a web service for handling these requests using SOAP/REST/JSON (no experience doing this, but would like to learn if it's a better implementation)
Write PHP scripts (enough experience to get by) that will grab data username/password/requests securely from my NSURLRequest and echo the NSData as XML and parse it with an NSXMLParser.
Are there other options? Is one a better implementation over the other? (web services come up more in searches)
Thank you in advance for taking the time to read my question and possibly clearing up any confusion.
Whoa! Web Services! Oh wait, calling a PHP script that returns JSON is actually also a web service. Well, that makes things simpler :-)
Yeah, so I would go for this:
Write a PHP script that returns JSON data (many tutorials available)
Protect the PHP script by setting up 'Basic access authentication' (Apache documentation)
Tell Apache to take the user database from your mysql database
Run your service on secure (HTTPS) web server (important because basic auth is not secure)
This way you can use almost all standard components on the iPhone side. NSURLConnection will talk HTTP(S) and there are excellent open source JSON parsers for Objective-C.
