Find out if an NSDate is today, yesterday, tomorrow

Question

With the iOS SDK I need to find an easy and secure way to see if an NSDate is today, yesterday, tomorrow. What I'm looking for is something like this in pseudo code:

NSDate *myDate = someDate;
if ([myDate isTomorrow]) {
    NSLog("Tomorrow"); 
}

How would you solve it?

Answer 1

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.
