Lets assume I have the string:

"Hello I like your shoes #today...!"

I am tokenizing the string by spaces:

return [string componentsSeparatedByString:@" "];

So my array contains:

Hello
I
like
your
shoes
#today...!

I want to focus on "#today...!" any word that has a # in the prefix I am changing the font color.

How can I make sure that only "#today" has its font color changed?

I would basically like to figure out if a word has a punctuation mark at the end, and change the color for characters before the punctuation mark.
