Looks like you want to write your own formatter :-)
Apple provide some two formatters for your convenience, but you can 
create your own, and use methods like
- (BOOL)isPartialStringValid:(NSString **)partialStringPtr 
proposedSelectedRange:(NSRangePointer)proposedSelRangePtr 
originalString:(NSString *)origString 
originalSelectedRange:(NSRange)origSelRange errorDescription:(NSString 
**)error
are interesting for what you want to do.

See NSFormatter doc for more informations.
