You can use compare: method to find which date is earlier or later check the documentation on this

http://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSDate_Class/

Edit: 

NSDateFormatter * formatter= [NSDateFormatter alloc] init];
NSDate *date = [formatter dateFromString:stringDate];
[formatter release];

then compare them.

You can use the compare method of the NSDate class

[myDate compare:someOtherDate]

This will return one of three values of type NSComparisonResult...

  • NSOrderedSame if both dates are equal
  • NSOrderedDescending if myDate comes after someOtherDate
  • NSOrderedAscending if myDate comes before someOtherDate
