Retrieve all contacts phone numbers in iOS

Question

So far I saw methods to get multiple phone numbers if I show a picker so user can select people and then get the phone number. What I want is retrieving all contacts

Answer 1

Sure you can. First you'll need to get the user permission for doing so. If you won't the user will have to manually authorize your app from the settings. There's a great example on how to retrieve all phone numbers, names, addresses etc' here.
