NSCalendardDate has
- (id)initWithString:(NSString *)description
- (id)initWithString:(NSString *)description calendarFormat:(NSString
*)format
- (id)initWithString:(NSString *)description calendarFormat:(NSString
*)format locale:(NSDictionary *)locale
NSDate has
- (NSCalendarDate *)dateWithCalendarFormat:(NSString *)formatString
timeZone:(NSTimeZone *)timeZone
and
- (NSComparisonResult)compare:(NSDate *)anotherDate
NSCalendarDateDate *aDate = [[NSCalendarDateDate alloc]
initWithString:theString] calendarFormat:@"%d/%m/%y"] ;
// or %m/%d%y or %y/%m/%d or %y/%d/%m or
// provided example doesn't tell
// see
// file:/Developer/Documentation/Cocoa/Conceptual/DataFormatting/Tasks/
SettingFormatForDates.html
// for more info on format strings
switch ([aDate compare:theOtherDate]) {
...
The main question would be: are the input strings all in the same
format and do you know it or the application has the guess it from
input ?
If the input is from a NSTextField you better had a NSDateFormater to
the text field with the accepted format and directly ask for the NSDate
to the formater ([ibMyDateField objectValue] and not [ibMyDateField
stringValue]...).
If the input is from imported text files, either you ask the user,
either you work with two pass, keeping the original text in memory,
converting each entry to the 6 possibilities, counting the errors for
each version, and suggesting the one with the min of errors when you
are done reading the file
