Answer 1

For web transfers, you can do HTTP REST very easily so I would architect your server side to talk very simple HTTP. There is built-in support for XML, but you will have to parse results from the server manually.

For Tab UI support, you can just look at the examples included in the SDK, it's not difficult.

For graphical output, you will want to create your own UIViews that override the draw function. You will have to learn the CoreData API in order to produce high-quality renderings.

If you are new to this, and are more familiar with C# or even Java, I highly recommend looking at the MonoTouch system.

Answer 2

HTTP rest requests are very easy, and can be architected as non-blocking on the client side. The iPhone has minimal support for XML and JSON is far easier (IMHO) using one of the json libraries such as those here.

You may want to use the deviceID as the unique user identifier (depends on your definition of unique I guess)

To learn iPhone programming, I can highly recommend the CS193P course available (at the moment) on iTunesU.

Hi Sapna, First of all u need a Mac based system and the iPhone SDK installed. I think you are trying to make an iphone version of the web application. it will be better for you to download the MAMP(Macintosh Apache MySQL PHP) Server and install it to debug your application. its simply the mac version of WAMP and LAMP. (hope you are familiar with PHP).

You can then configure you MAMP for debugging and once the debug is complete you can host these PHP files to the actual server.

Remember, you need to get the results from the server in the XML format. and you need to write code to parse the XML you generated at the server.

Hope this information is helpful.
