Solution 1

In the following, yourDate represents your input NSDate; nextDate represents the next day.

// start by retrieving day, weekday, month and year components for yourDate
    NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
    NSDateComponents *todayComponents = [gregorian components:(NSDayCalendarUnit | NSMonthCalendarUnit | NSYearCalendarUnit) fromDate:yourDate];
    NSInteger theDay = [todayComponents day];
    NSInteger theMonth = [todayComponents month];
    NSInteger theYear = [todayComponents year];

    // now build a NSDate object for yourDate using these components
    NSDateComponents *components = [[NSDateComponents alloc] init];
    [components setDay:theDay]; 
    [components setMonth:theMonth]; 
    [components setYear:theYear];
    NSDate *thisDate = [gregorian dateFromComponents:components];
    [components release];

    // now build a NSDate object for the next day
    NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
    [offsetComponents setDay:1];
    NSDate *nextDate = [gregorian dateByAddingComponents:offsetComponents toDate:thisDate options:0];
    [offsetComponents release];
    [gregorian release];

Solution 2

NSDate *tomorrow = [NSDate dateWithTimeInterval:(24*60*60) sinceDate:[NSDate date]];

Much more easiest way..

Solution 3

what about this methods ?

http://www.drobnik.com/touch/2009/05/adding-days-to-nsdate/

NSDate *now = [NSDate date];
int daysToAdd = 50;  // or 60 :-)

// set up date components
NSDateComponents *components = [[[NSDateComponents alloc] init] autorelease];
[components setDay:daysToAdd];

// create a calendar
NSCalendar *gregorian = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];

NSDate *newDate2 = [gregorian dateByAddingComponents:components toDate:now options:0];
NSLog(@"Clean: %@", newDate2);

Solution 4

I guess this method works just fine for me.

NSString *zajtra = [[NSDate date] dateByAddingTimeInterval:86400];

Solution 5

//Add the below code to init method or viewDidload

[[NSUserDefaults standardUserDefaults] setObject:[NSDate date]  forKey:@"Date"];

//Add this code where you wanna retrieve next or previous dates

NSDate *tomorrow = [[NSUserDefaults standardUserDefaults] valueForKey:@"Date"];
NSTimeInterval secondsPerDay = 24 * 60 * 60;    
NSDate *date = [tomorrow addTimeInterval:secondsPerDay]; //Change NSDate *date = [tomorrow addTimeInterval:-secondsPerDay]; for yesterday
tomorrow = date;
[self setDate:tomorrow];
dateTextField.text = [self getDate];        
[[NSUserDefaults standardUserDefaults] setObject:tomorrow  forKey:@"Date"];

  You should mark one of the answers below correct if you feel it answers your question.

Hi, Yeah this code's working Thanks a lot, Do you have any idea about how to get previous day(yesterday)?

Changing [offsetComponents setDay:1] to be setDay:-1 results in subtracting a day instead of adding
Niels Castle over 14 years

Cave: Repeatedly adding secondsPerDay (24 * 60 * 60) with addTimeInterval to an NSDate is done while observing daylight saving time. Adding 24 hours on a day when you enter or leave daylight savin time skews the time of day by +/- 1 hour.

This can cause issues when traversing day boundaries when accounting for DST.

This can give incorrect results when there is a Daylight Savings Time change in the range of dates.

Ditto, This can give incorrect results when there is a Daylight Savings Time change in the range of dates.

This also works when the next date moves from daylight savings to standard time. Try moving from 2011-11-06. Thanks @unforgiven.

This code should crash because you are releasing components twice.

@singingAtom, I have updated my answer, thank you.

Also when there is a leap second.

Will not do what you expect if there is a leap second.

Much better solution than the most upvoted in this topic

Why does your - [NSDate dateByAddingTimeInterval:] return a NSString?

This is not valid.. This will give date with same time after 24 hours.

Also breaks if the user travels between time zones.

It does not take care of the leap second as well. Hence it will break.

Works like a breeze!

also useful [NSCalendar currentCalendar]

I take the points above but in some cases, e.g. when you just want a date in the future for testing, this is a simple solution.
