Check if string contains a hashtag and then change hashtag color
===

Im developing an iPhone app that fetches tweets from twitter. I'm doing this through Json and everything is working fine. I'm looking to search each tweet and see if it contains a hashtag and then change the color of that specific tag. 

For example  : "This is a tweet #MYTWEET"

So I want "This is a tweet" to be one color and "#MYTWEET" to be a separate color. I know how to search for a hashtag but I can't seem to figure out how to change just the text following.
