Yes it is possible. For doing this you will be using the method of Parsing . Depending on the type of API you are getting whether it is JSON, XML or HTML etc , you can parse the desired data accordingly. You can check for the API's on the web for the type of information you would want to parse. Otherwise the database option is always there.

You can use a HTML Parser or use Regex to extract the pattern of the data that you want from the given url . However try to check whether the data provided by the website is copyrighted or not else you cannot use their data publicly via another interface without their permission.

I am not an iOS developer, so I can't give you code on how to do it.

You'll be needing an HTML parser. The process is commonly called web/screen scraping. Have a read at this: https://stackoverflow.com/a/3541965/459338
