NSDatePicker - getting value when changing it

Question

How do I get notified of an NSDatePicker value when it changes?

Answer 1

I just did it on an iPhone with UIDatePicker, but it looks like a Mac, you register as a delegate and receive messages. See Apple Docs here .

I have to clarify, this tells you when it has changed, you still need to call -dateValueto get the date.

Answer 2

The same would be with any other control. Possible options:

• Target / Action
• Snap
• Observe notice
• delegate

Answer 3

picker value ( ).
