How can i get date of a coming day - Objective C [duplicate]

问题

If I say upcoming monday then how can I get date of upcoming monday?

Like, today is Thu, 04-04-2013 than how can I get what date will be on coming wednesday?

Hope I am able to clarify you.

回答1:

NSCalendar *gregorian = [[NSCalendar alloc]initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *date = [NSDate date];
NSDateComponents *weekdayComponents = [gregorian components:NSWeekdayCalendarUnit fromDate:date];
NSInteger todayWeekday = [weekdayComponents weekday];

enum Weeks {
    SUNDAY = 1,
    MONDAY,
    TUESDAY,
    WEDNESDAY,
    THURSDAY,
    FRIDAY,
    SATURDAY
};

NSInteger moveDays=WEDNESDAY-todayWeekday;
if (moveDays<=0) {
    moveDays+=7;
}

NSDateComponents *components = [NSDateComponents new];
components.day=moveDays;

NSCalendar *calendar=[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar];
NSDate* newDate = [calendar dateByAddingComponents:components toDate:date options:0];

NSLog(@"%@",newDate);

Just to irritate Anoop ;) :

NSDate* now = [NSDate date];
NSTimeInterval nowInterval = [now timeIntervalSince1970];
int days = (int)(nowInterval / (24 * 60 * 60));
int today = (days + 4) % 7;
NSDate* saturday = [NSDate dateWithTimeIntervalSince1970:nowInterval + (6 - today) * 24 * 60 * 60];
NSLog(@"saturday = %@", saturday);
