You can use

[datePicker.date timeIntervalSinceNow]

which returns an NSTimeInterval (just a typedef for a double, in units of seconds) which is positive for the future and negative for the past.

As the doc says, compare provides subsecond comparison, so you can use this to force their date to be a full day later (instead of just sometime in the future).
