How to tell ABPeoplePickerNavigationController to list only contacts that have an email address?
问题 I want my users to fill an email field by selecting a contact's email from their address books. I don't want them to scroll all the contacts whose emails are not set, so I want to filter the ones that have email addresses. This is the code I've written so far. I can figure out who has an email address and who has not but I couldn't tell the ABPeoplePickerNavigationController to list only the right contacts. Is it impossible to achieve this, I mean do I have to implement my own contact picker
