Features

KNContactsPicker is a modern, customisable and easy to use Contacts Picker similar to the stock CNContactPickerViewController. It does improve in a couple of area for a better UX.

• Three contact selection modes:
  • Single Deselect (Deselects all other contacts after first contact is selected)
  • Single Reselect (Selects another contact on tap)
  • Multi Select
• Contact images or initials
• Search contacts and ability to select while searching
• Clear selection button
• Contact section indexes to quickly navigate through the contact list
• Returns CNContact objects
• Highly customisable settings for strings and options
• Two conditional methods to enable or deselect certain contacts
• Support iOS 13
  • Dark Mode
  • Icons (SF Symbols)
  • Pull to Dismiss

Coming soon:

• Extra contact info under name
• Contact sort order
• Contact display order
• More modular contact property approach

Make sure your app (the host app) has provided a Privacy - Contacts Usage Description in your Info.plist. It's also recommended that you check that contact authorisation is granted.

How to use

Implement the Delegate Methods

// This is in your application
extension ViewController: KNContactPickingDelegate {
    func contactPicker(didFailPicking error: Error) {
        print(error)
    }
    func contactPicker(didCancel error: Error) {
         print(error)
    }
    func contactPicker(didSelect contact: CNContact) {
        self.contacts.append(contact)
        self.contactsTableView.reloadData()
    }
    
    func contactPicker(didSelect contacts: [CNContact]) {
        self.contacts.append(contentsOf: contacts)
        self.contactsTableView.reloadData()
    }
}

Customise the Settings

var settings = KNPickerSettings()
settings.pickerTitle = "Pick"

settings.conditionToDisplayContact = { contact in
  return contact.organizationName == "Apple"
}
settings.conditionToDisableContact = { contact in
    return self.contacts.contains(contact)
}

Initialise and Present the KNContactsPicker

let controller = KNContactsPicker(delegate: self, settings: settings)
        
self.navigationController?.present(controller, animated: true, completion: nil)
