Fetch contact with new Contact framework
Posted By : Aditya Kumar Sharma | 06-Jan-2017
Apple has introduced the new framework Contacts. It has replace the function based AddressBook framework. Contacts framework provides object-oriented approach to work with user contact info.
So here we are going to Fetch contacts from the device but with new Contact framework which came in iOS 9.
So follow these simple steps for Fetching contacts.
1. Import Contact framework in the file
import Contacts
2. Then we have to check for authorisation. If user has not allowed then we have get permission from user to fetch the contacts. for checking the authorisation you can use the following method:
public func askForContactAccess() -> Dictionary {
var data = Dictionary()
let authorizationStatus = CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts)
switch authorizationStatus {
case .Authorized:
// data = fetchContacts()
// will fetch the contacts
case .Denied, .NotDetermined:
dispatch_async(dispatch_get_main_queue(), { () -> Void in
self.displayCantAddContactAlert()
})
break
default:
break
}
return data
}
In this method we checking for authorisation status. If it is not been authorised then we are going to show a pop Up to make user allow for contact fetching.
func displayCantAddContactAlert() {
let cantAddContactAlert = UIAlertController(title: TextMessages().cannotAddcontactMessage, message: TextMessages().mustGivePermissionMessage, preferredStyle: .Alert)
cantAddContactAlert.addAction(UIAlertAction(title: TextMessages().changeSettingTitle, style: .Default, handler: { action in self.openSettings()}))
cantAddContactAlert.addAction(UIAlertAction(title: TextMessages().okAlertTitle, style: .Cancel, handler: nil))
UIApplication.topViewController()?.presentViewController(cantAddContactAlert, animated: true, completion: nil)
}
func openSettings() {
let url = NSURL(string: UIApplicationOpenSettingsURLString)
UIApplication.sharedApplication().openURL(url!)
}
4. Now when user has authorised the app to fetch the contacts. Now we have to fetch all the contacts and have to store them in the array with a key attached to them. Like for saving name we give the key “name” and for phone number we give “number”.
func fetchContacts() -> Dictionary {
let contactsArray = NSMutableArray()
let requestForContacts = CNContactFetchRequest(keysToFetch: [CNContactIdentifierKey, CNContactFormatter.descriptorForRequiredKeysForStyle(CNContactFormatterStyle.FullName), CNContactPhoneNumbersKey ,CNContactThumbnailImageDataKey])
do{
try contactStore.enumerateContactsWithFetchRequest(requestForContacts) { (contactStore : CNContact, stop: UnsafeMutablePointer) -> Void in
contactsArray.addObject(contactStore)
}
}
catch {}
if contactsArray.count > 0 {
let formatter = CNContactFormatter()
for contactTemp in contactsArray
{
let contactNew = contactTemp as! CNContact
//Contact Name
var stringFromContact = formatter.stringFromContact(contactNew)
if stringFromContact == nil {
stringFromContact = "Unnamed"
}
//Identifier
let stringFromIdentifier = contactNew.identifier
var tempArray : NSArray = NSArray()
if (contactNew.phoneNumbers).count > 0 {
tempArray = ((contactNew.phoneNumbers as? NSArray)?.valueForKey("value").valueForKey("digits")) as! NSArray
for i in 0 ..< tempArray.count {
let newDict = NSMutableDictionary()
let phoneNumber : String = (tempArray.objectAtIndex(i)) as! String
if phoneNumber.characters.count > 0 {
let resultString : String = (phoneNumber.componentsSeparatedByCharactersInSet(NSCharacterSet.symbolCharacterSet()) as NSArray).componentsJoinedByString("")
newDict.setValue(stringFromIdentifier, forKey: "recordID")
newDict.setValue(resultString, forKey: "phonenumber")
newDict.setValue(stringFromContact, forKey: "name")
self.contactDetails.append(newDict)
}
}
}else{ // no number saved
}
}
}else {
print("No Contacts Found")
}
}
here we fetched all the contacts with the help of framework and stored them in the ContactDetails array with a key attached to them. Now we can use this array to show the Contacts in our App.
