Stepper to Modify A Date. Bad Idea or Good Idea?

Stepper to Modify A Date. Bad Idea or Good Idea?

I have looked for examples of where there is a simple date in a text field
(IPhone) and a stepper next to the field to increment or decrement the
date (by one day) but have not seen any examples or usage implementation.
So I'm wondering if this goes against any Apple UI Human Interface
Guidelines.
I am creating a business app that has many different date attributes to be
stored with Core Data. The user will supply date info in various sessions,
typically within 0-4 days of the actual current date. So my thinking is,
throw up the view, put in the current system date, and let the user tap a
stepper next to the date input field in question to increment the date
up/down by 1 day, formatting the text field accordingly to be saved
propery. (Rather then having the user change the date via the keyboard or
a datepicker subview) Any thoughts on why this is or is not a good idea in
terms of UI or Apple guidelines?
Thanks
