Tic-tac-toc game almost ready

My first tic-tac-tao game almost ready. Got some break through with the logic yesterday. The 2 players mode is working perfectly (I think), still have some problems with the 1 player mode. As the "AI" for the computer player can only as smart/dumb as the person who wrote it. So if you found the computer player not smart enough, then it's entirely my fault ha ha...Will try to get it done in the next few days. Now, how do I attach a file in this blogger.com blog thing?

Question: Differences in handling touch event between UIView and UIImageView?

I was studying about the "touch" events on iOS4 and looking at some examples from various areas, including books and net.
