BPDeveloper's solution works, except during daylight savings changeovers where relevant. For example, if you're in any US timezone and currentDate is 12:30 am on November 6, 2011, then adding 24 hours to that time actually gives you 11:30pm on November 6, 2011 because of the daylight savings changeover.

Here's an alternative solution that avoids that problem:

NSDate *currentDate = [NSDate date];
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
[offsetComponents setDay:1];
NSDate *nextDate = [gregorian dateByAddingComponents:offsetComponents toDate: yourDate options:0];

You could use something like this:

NSDate *currentDate = [NSDate date]; // This could of course be whatever date you want.
NSDate *newDate = [[currentDate] dateByAddingTimeInterval:3600 * 24];
