I want to make an ios 7 application that fetches online stock data (such as % change), but i have no idea how i can actually fetch the data. i've been looking into json, but i don't know if that is the right thing to use.

i would like to know how i can fetch data from this site to use it in my project, so i can store a % change value in a number/integer to use it in an if-else statement.
any help is much appreciated!
