Question

I need to be able to store the current NS Date plus 7 days. I already store the current NSDate. I then want to compare the two dates, to get the number of days difference between the two and display within a label. The idea is to count down from 7 days, to 6 days, to 5 days, etc until it shows 0 and i will remove it from my tableview.

I have been having hard time finding the write code for this, so any help would be greatly appreciated!!!

Answer 1

This code will compute date after 7 days from today.

NSDateComponents *comps = [NSDateComponents new];
comps.day = 7;

NSDate *today = [NSDate date];

NSCalendar *c = [NSCalendar currentCalendar];
NSDate *dateAfter7days = [c dateByAddingComponents:comps toDate:today options:0];

For Your date diffrence the code is:-

    // c is calendar object
    NSDateComponents *comps = [c components:NSDayCalendarUnit fromDate:startDate toDate:currentDate options:0];
    int diffrence = [comps day];
