iPhone Stock Search

[amprab]

Does anyone know how to implement search functionality like the Stock app or Weather app or the Amazon.com app on iPhone were you have to get the data from some external source in the cloud based on what you type. Does this require some web service call? Or is there any other way to do this?

I mean if you want to search for lets say restaurants would you need to find some pre-exisisting web service which supports this and then call it.

Thanks

Yes, you'd need some existing data provider that you can query for information. You usually make an XML http request and display the results to the user.

If you have the data, you'll have to create a web service to serve the data to the app (PHP is a typical language for this.)
