Question

I have two (2) UIDatePickers in my iPad app (XCode 4.5, Storyboards, iOS 6.0). One UIDatePicker is used for a “start” date/time, the other is for “end” time (does not show the date, just the time).

I want to be able to set the second picker (“end” time) date to equal what was selected in the “start” date/time picker.

I have looked in Google and SO, and can find nothing. How do I do this?

Answer 1

If on different view and controller then you need to pass the date to other class.
For this you can use a delegate or notification.

and then use something like this

Use [secondDatePicker setDate:firstDatePicker.date]

If both are on same controller then, you can simply add an action method as :

- (IBAction)datePickerValueChanged:(UIDatePicker *)picker {
  _secondDatePicker.date = picker.date;
}
