What I used to do was using the timestamp and then adding 86400 seconds ( 24 * 60 * 60 ). As I read a recent question on stackoverflow noting that that is not correct for every day, I want to change this.

So the next thing I came up with was by using NSDateComponents. I simply get the current day and add 1. Now I was wondering how “smart” that is. Like if the day is equal to 31, does it set the day to 1 and the month to whatever it is +1 ( or when it is 12 to 1 again ) ? I can do this manually but that would only work properly for the gregorian calendar so I don’t really know whether that would be a good solution either..

    It is smart, unless you want it to be dumb.

    From the documentation for -[NSCalendar dateByAddingComponents:toDate:options]:

    If you specify no options (you pass 0), overflow in a unit carries into the higher units (as in typical addition).

    If you did not want units overflowing into higher units, then you would pass “NSWrapCalendarComponents” as the value of the options: parameter.
