How to get NSDate day, month and year in integer format?

I want to get the day, month and year components of NSDate in integer form i.e. if the date is 1/2/1988 then I should get 1, 2 and 1988 separately as an integer. How can I do this in iOS? I found the similar question but the method descriptionWithCalendarFormat: gives a warning and seems to be deprecated by now.

Here you are,

NSDate *currentDate = [NSDate date];
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:currentDate]; // Get necessary date components

 [components month]; //gives you month
 [components day]; //gives you day
 [components year]; // gives you year

You can use NSDateComponents for that as above.

Please visit this page for details.

Yes by the use of NSCalendar, though, i think this will make your work.

NSDateComponents *components = [[NSCalendar currentCalendar] components:NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit fromDate:[NSDate date]];
NSInteger day = [components day];    
NSInteger month = [components month];
NSInteger year = [components year];

Swift

let components = NSCalendar.currentCalendar().components([.Day, .Month, .Year], fromDate: self)
let day = components.day
let month = components.month
let year = components.year

For convenience you can put this in an NSDate extension and make it return a tuple:

extension NSDate: Comparable {

    var dayMonthYear: (Int, Int, Int) {
        let components = NSCalendar.currentCalendar().components([.Day, .Month, .Year], fromDate: self)
        return (components.day, components.month, components.year)
    }
}

Now you have to write only:

let (day, month, year) = date.dayMonthYear

If you wanted to e.g. get only the the year you can write:

let (_, _, year) = date.dayMonthYear

You can use NSDateComponents to get this,

NSCalendar *calendar = [NSCalendar autoupdatingCurrentCalendar];
NSDate *currDate = [NSDate date];
NSDateComponents *dComp = [calendar components:( NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit ) 
									  fromDate:currDate];

int day = [dComp day];
int month = [dComp month];
int year = [dComp year];

Put it in an extension and live your life 

extension Date{
	var day:Int {return Calendar.current.component(.day, from:self)}
    var month:Int {return Calendar.current.component(.month, from:self)}
    var year:Int {return Calendar.current.component(.year, from:self)}
}
Date().day//22
Date().month//4
Date().year//2017

Swift 3.0 (It's an iteration of previous answers, but solves it for all your future app projects)

To those who just copy and paste directly from the web, like me, this is a small update for iOS 8

NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* components = [calendar components:NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay fromDate:[NSDate date]];
[components day]; //Day
[components month];//Month
[components year];//Year

The difference is NSCalendarUnitYear|NSCalendarUnitMonth|NSCalendarUnitDay NSMonthCalendarUnit | NSDayCalendarUnit | NSYearCalendarUnit | NSWeekdayCalendarUnit have been deprecated

U can try this .......

Mycal = [NSCalendar currentCalendar];
today = [NSDate date];
compA =[Mycal components:(NSMonthCalendarUnit | NSDayCalendarUnit | NSYearCalendarUnit | NSWeekdayCalendarUnit) fromDate:today];	 
FirstDateofMonth=[today dateByAddingTimeInterval:([compA day]-1)*(-24*60*60)];

compA =[Mycal components:(NSMonthCalendarUnit | NSDayCalendarUnit | NSYearCalendarUnit | NSWeekdayCalendarUnit) fromDate:FirstDateofMonth];
today = FirstDateofMonth;
compA = [Mycal components:(NSMonthCalendarUnit | NSDayCalendarUnit | NSYearCalendarUnit | NSWeekdayCalendarUnit) fromDate:today];
[compA setMonth:([compA month])];
[self DrawMonthInPortraitView];
[compA retain];

NSDate *currentDate = [NSDate date];
NSCalendar* calendar = [NSCalendar currentCalendar];
NSDateComponents* components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit fromDate:currentDate]; // Get necessary date components

[components month]; //gives you month
[components day]; //gives you day
[components year]; // gives you year

NSString *temp=[NSString stringWithFormat:@"Months:%d Day:%d Year:%d",[components month],  [components day],[components year]];
NSLog(@"%@",temp);

let date = Date()
let calendar = Calendar.current

let year = calendar.component(.year, from: date)
let month = calendar.component(.month, from: date)
let day = calendar.component(.day, from: date)
print("hours = \(year):\(month):\(day)")
