The code Richard sent is creating a dummy font and asking for its size. The problem is that there are about 3 thousand different fonts on the Mac ;-)
Here we are creating a CTFont. For Mac OS X most native apps probably would be using a NSFont (cause that is what cocoa controls take). Likewise on iOS I think the "common" font is UIFont (cause I think that is what UIKIt controls take). Could anyone fire up Xcode, create a dummy iOS app, create a UIFont and see what is the size ?
