iOS Storing, in order, text from a pdf

[Ja Di ksw]

Hi everyone,
Is there a simple way to read/store the words from a pdf in order (for example, putting them in a NSMutableArray?) so each word can be retrieved later?
Thanks!

You could read the file into an NSString and then use the NSString method "componentsSeparatedByString:"

This should help

-Convert the PDF to an NSString
-Use componentsSeparatedByString to create an array of words
-Use sortedArrayUsingSelectorselector(caseInsensitiveCompare) to sort the array.

You'll have tons of duplicate words. You might want to remove those. To do that you could convert the array into an NSOrderedSet or NSMutableOrderedSet and sort that.

How hard is this step?

I actually don't know for sure. I've never needed to.

I completely glossed over the fact that it said PDF to NSString. A pdf could be tough, especially given that a lot of pdfs are created differently.

through a quick google search I found this

Thanks for all the help (and sorry about my late reply, been insanely busy). I'll give it a go this week and see how it works.
