Detecting touched character

I'm looking for the best way to detect a character (in a short string, drawn in a large font) touched by the user, and send an accompanying event. It looks like I might be able to do this by looking at the location of a touches ended event inside of a UILabel with "User Interaction Enabled" turned on, or maybe by programmatically creating a row of transparent buttons, each with a single character title ([A][P][P][L开发者_JS百科][E]), but before attempting that I wanted to tap the collective wisdom here and see if maybe I might be overlooking something easy and obvious...

Any ideas?

I think the two easy options would be experimenting with a row of labels or buttons to see what works best, just like you suggested. If that wont work you have to create your own UIView (possibly extending UILabel) and dive into the drawing code to find out the exact location of a 'printed' character to determine where the user touches.
