Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
This of coarse works fine, but what if you didn't know the exact path. In Linux you could always do some sort of recursive search. For example, in the "pic" directory that I specified in the latter case what if there was other directories called pic1,pic2,pic3 etc and each directory had an arbitrary number of png's. What I am having a hard time wrapping my head around is how can I recursively search the "pic" directory to extract all directories contents that match .png. I would of coarse then store this is NSData and convert to a string and then store the contents in an array. I'm very much confused at this point. Any help would be greatly appreciated.
