See documentation about NSDateFormatter and NSString.


To get the integer value of the first two characters of a string you 
could write

int value = [[theString substringToIndex:2] intValue];


Date formatting is a complex problem. For system versions prior to 
10.4 support for date formatting was - um - bad. Support in Tiger 
seems to be much better. Since I don't have too much experience with 
the new date related methods, I suggest you read up on it yourself:

DataFormatting/DataFormatting.html

I don't know what your target audience is, so I can't say if this is 
indeed all you need. But please note that there are a *lot* more date 
formats than those two.
