Answer 1

Use NSDateComponents and NSCalendar.

NSDate *date = [NSDate date]; // 2012-12-08 09:46:31 +0000
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
[components setDay:2]; // your example of 2 days
date = [calendar dateByAddingComponents:components
                                 toDate:date options:0];
// 2012-12-10 09:46:31 +0000
