i know asked many times not answer.please help me.

the way did on our server gave api "page size" parameter when request info like:

http://www.truemanindiamagazine.com/webservice/news.php?page=3&pagesize=5

it returns 5 results instead of default amount, 10 in case. means don't have fancy filtering on ios side of things.
