У меня была такая же проблема, но в Swift, я воспользовался предложением Nik Burns и написал об этом в блоге: http://paulpeelen.com/2016/01/20/prefill-an-signup-form-in-ios-using-swift-and-cncontact/
Это в основном конечный результат в Swift:
import Contacts
...
@IBOutlet weak var nameFirst: UILabel!
@IBOutlet weak var nameLast: UILabel!
@IBOutlet weak var email: UILabel!
@IBOutlet weak var phoneNo: UILabel!
@IBOutlet weak var address: UILabel!
/**
Search the addressbook for the contact
*/
private func getMe() {
let ownerName = getOwnerName()
let store = CNContactStore()
do {
// Ask permission from the addressbook and search for the user using the owners name
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName(ownerName), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactPostalAddressesKey, CNContactEmailAddressesKey])
//assuming contain at least one contact
if let contact = contacts.first {
// Checking if phone number is available for the given contact.
if (contact.isKeyAvailable(CNContactPhoneNumbersKey)) {
// Populate the fields
populateUsingContact(contact)
} else {
//Refetch the keys
let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactPostalAddressesKey, CNContactEmailAddressesKey]
let refetchedContact = try store.unifiedContactWithIdentifier(contact.identifier, keysToFetch: keysToFetch)
// Populate the fields
populateUsingContact(refetchedContact)
}
}
} catch let e as NSError {
print(e.localizedDescription)
}
}
/**
Get the device owners name
- returns: The owners name
*/
private func getOwnerName() -> String {
// Get the device owners name
var ownerName = UIDevice.currentDevice().name.trimmedString.stringByReplacingOccurrencesOfString("'", withString: "")
// Get the model of the device
let model = UIDevice.currentDevice().model
// Remove the device name from the owners name
if let t = ownerName.rangeOfString("s \(model)") {
ownerName = ownerName.substringToIndex(t.startIndex)
}
return ownerName.trimmedString
}
/**
Populate the fields using a contact
- parameter contact: The contact to use
*/
private func populateUsingContact(contact: CNContact) {
// Set the name fields
nameFirst.text = contact.givenName
nameLast.text = contact.familyName
// Check if there is an address available, it might be empty
if (contact.isKeyAvailable(CNContactPostalAddressesKey)) {
if let
addrv = contact.postalAddresses.first,
addr = addrv.value as? CNPostalAddress where addrv.value is CNPostalAddress
{
let address = "\(addr.street)\n\(addr.postalCode) \(addr.city)\n\(addr.country)"
self.address.text = address
}
}
// Check if there is a phonenumber available, it might be empty
if (contact.isKeyAvailable(CNContactPhoneNumbersKey)) {
if let
phonenumberValue = contact.phoneNumbers.first,
pn = phonenumberValue.value as? CNPhoneNumber where phonenumberValue.value is CNPhoneNumber
{
phoneNo.text = pn.stringValue
}
}
}
И расширение:
extension String {
/// Trim a string
var trimmedString: String {
return stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceAndNewlineCharacterSet())
}
}
