How would you get the date of the the first saturday that occurs after today in Objective-C for iOS?
This will guide you through the process of manipulating calendar dates:
Calendrical Calculations
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=SATURDAY-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);
[NSDate dateWithNaturalLanguageString: @"next Saturday"]
Edit: Starting in OS X 10.9 and iOS 8, you can do this:
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDate *now = [NSDate date];
NSDateComponents *saturday = [[NSDateComponents alloc] init];
saturday.weekday = 7 /* Saturday */;
NSDate *nextSaturday = [calendar nextDateAfterDate:now matchingComponents:saturday options:0];
