Modifying NSDate to represent 1 month from today

Anonymous User 2032 31-Aug-2015

I'm adding repeating events to a Cocoa app I'm working on. I have repeat every day and week fine because I can define these mathematically (3600*24*7 = 1 week). I use the following code to modify the date:

 

[NSDate dateWithTimeIntervalSinceNow:(3600*24*7*(weeks))]

 

I know how many months have passed since the event was repeated but I can't figure out how to make an NSDate object that represents 1 month/3 months/6 months/9 months into the future. Ideally I want the user to say repeat monthly starting Oct. 14 and it will repeat the 14th of every month.

Use NSCalender, NSDateComponents and NSDate:

NSDateComponents *components = [[[NSDateComponents alloc] init]
                               autorelease];
components.month = 1;
NSDate *oneMonthFromNow = [[NSCalendar currentCalendar] dateByAddingComponents:
                          components toDate:[NSDate date] options:0];

Just set the different properties of components to get different periods of time (e.g. 3 months, 6 months etc).

Note: Depending on the context, you may want to use [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease] instead of [NSCalendar currentCalendar], if by "1 month" you mean "1 month on the Gregorian calendar".
