NSXMLParser Syntax and Setup

Question

I am using NSXMLParser to parse the RSS2 feed of a "Wordpress blog", and pass the contents of certain tags to certain lines or image views within a table view cell. I have read many posts on how to implement NSXMLParser, however I'm still kinda lost, and would like someone to review my code for errors as well as community input. I feel like there are some parts missing as well. The goal is to parse the title, "pubDate", "img", and "description".

XML:

<rss xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:slash="http://purl.org/rss/1.0/modules/slash/" version="2.0">
