You can use NSDateComponents and NSCalendar to perform this sort of calculation. For example, assuming a Gregorian calendar, you can use an NSDateComponents object with weekday=7 and weekdayOrdinal=5 to represent "fifth Saturday", and use NSCalendar enumerateDatesStartingAfterDate:matchingComponents:options:usingBlock: to find "fifth Saturdays" after some starting date. -- Greg Parker [email protected] Runtime Wrangler _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
