How do I add 1 day to an NSDate?

Question

Basically, as the title says. I'm wondering how I could add 1 day to an NSDate.

So if it were:

21st February 2011 

It would become:

22nd February 2011 

Or if it were:

31st December 2011 

It would become:

1st January 2012. 

Answer 1

Swift 5.0 :

var dayComponent    = DateComponents() dayComponent.day    = 1 // For removing one day (yesterday): -1 let theCalendar     = Calendar.current let nextDate        = theCalendar.date(byAdding: dayComponent, to: Date()) print("nextDate : \(nextDate)") 

Objective C :

NSDateComponents *dayComponent = [[NSDateComponents alloc] init]; dayComponent.day = 1;  NSCalendar *theCalendar = [NSCalendar currentCalendar]; NSDate *nextDate = [theCalendar dateByAddingComponents:dayComponent toDate:[NSDate date] options:0];  NSLog(@"nextDate: %@ ...", nextDate); 

This should be self-explanatory.

Since iOS 8 you can use NSCalendar.dateByAddingUnit

Example in Swift 1.x:

let today = NSDate() let tomorrow = NSCalendar.currentCalendar()     .dateByAddingUnit(          .CalendarUnitDay,           value: 1,           toDate: today,           options: NSCalendarOptions(0)     ) 

Swift 2.0:

let today = NSDate() let tomorrow = NSCalendar.currentCalendar()     .dateByAddingUnit(         .Day,          value: 1,          toDate: today,          options: []     ) 

Swift 3.0:

let today = Date() let tomorrow = Calendar.current.date(byAdding: .day, value: 1, to: today)
