I saw this post: iOS and finding Tomorrow.
The code provided is:
units = NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit;
NSDateComponen
Form a date component with number of days you want to add to your original date. From the current calendar form the date by adding the this component to your original date.
NSDateComponents *dateComponents = [NSDateComponents new];
dateComponents.day = 1;
NSDate *newDate = [[NSCalendar currentCalendar]dateByAddingComponents:dateComponents
toDate: selectedDate
options:0];
