How to check whether all fields are empty in ABNewPersonViewController

I have a custom button in ABNewPersonViewController. I need to enable the button, only if any(at least) one of the fields in ABNewPersonViewController is edited. Is there any way in which I can check this condition, other than writing code to check all fields independently.

Solution

  • You'll need some code somewhere to do this, but I'd do it by coding the existing event listener on each field to enable the button when the field being listened to is edited.
