You might want to take a look into the sources of OpenGroupware.org. We 
provide two different iCal SAX drivers as well as some higher level 
objects for dealing with iCal (NGiCal).

Why don't you use [NSData dataWithContentsOfMappedFile:]?

Well, since iCal is a text based format, you probably should first 
convert it to an NSString (initWithData:encoding:). Then you could use 
NSScanner or just write an own iCal parser which steps through the 
characters of the string.
