I understand that this is pretty old, but I want to bring the answer up to date (as I didn't see anyone else post a more up to date answer).

Since iOS 8.0 you have a bunch of functions that you can use for date comparison:

• compareDate:toDate:toUnitGranularity:
• isDate:equalToDate:toUnitGranularity:
• isDate:inSameDayAsDate:
• isDateInToday:
• isDateInTomorrow:
• isDateInWeekend:
• isDateInYesterday:

See below example:

NSDate *today = [NSDate new];
NSCalendar* calendar = [NSCalendar currentCalendar];

BOOL isToday = [calendar isDateInToday:today];
BOOL isYesterday = [calendar isDateInYesterday:today];

isToday will be YES.

isYesterday will be NO, given that we gave it todays date.
