Get a list of all contacts on iOS

Question

I want to get a list of all contacts of an iPhone.

I checked Address Book reference, I may missed something but I didn't see it provides a method to get a list of contacts.

Answer 1

Swift version:

override func viewDidLoad() {
    super.viewDidLoad()

    var error: Unmanaged<CFErrorRef>?

    var addressBook: ABAddressBook = ABAddressBookCreateWithOptions(nil, &error).takeRetainedValue()


    if ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.NotDetermined {
        ABAddressBookRequestAccessWithCompletion(addressBook,  {

            (granted:Bool, error:CFErrorRef!) -> Void in

            self.populateFrom(addressBook: addressBook)

        })
    }
    else if ABAddressBookGetAuthorizationStatus() == ABAuthorizationStatus.Authorized {

        self.populateFrom(addressBook: addressBook)

    }

}

func populateFrom(#addressBook:ABAddressBook){
    let allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue()
    let nPeople = ABAddressBookGetPersonCount(addressBook)
    for index in 0..<nPeople{
        let person: ABRecordRef = Unmanaged<ABRecordRef>.fromOpaque(COpaquePointer(CFArrayGetValueAtIndex(allPeople, index))).takeUnretainedValue()
        let firstName: String = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeUnretainedValue() as? String
        println("\(firstName.debugDescription)")


    }

}
