NSDate reference is a great little document:
http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSDate_Class/Reference/Reference.html

- (NSTimeInterval)timeIntervalSinceDate:(NSDate *)anotherDate

is what you are looking for if you want time interval difference.

For days (as not every day has same number of minutes, hours) you want to see Martins answer below and use NSDateComponents with [NSCalendar currentCalendar]
