Swift Contacts Frameworkを使用して、電話番号を使用して検索し、名前とユーザー画像を取得します
電話番号を+ 1415xxxxxxx（E164）の形式で返すAPIを持っています
現在、これらの数値はUITableViewのセルに入力され、期待どおりに表示されますが、電話でユーザーの連絡先を検索して、一致するものがあるかどうかを確認できます。一致する場合は、名も返します、姓、既知の写真。
Appleページを見て（ https://developer.Apple.com/library/watchos/documentation/Contacts/Reference/Contacts_Framework/index.html ）必要に
import ContactsUI
しかし、不明な点があります。contactDBを辞書に読み込んでから検索しますか？名前での検索では多くのことを見つけることができますが、番号での検索ではそれほど多くのことを見つけることができません。
let predicate = CNContact.predicateForContactsMatchingName("Sam")
私が呼び出すことができる関数に到達しようとしています。PhoneNumberを使用して検索し、FirstName、FamilyName、およびImageを返します。
func searchForContactUsingNumber(PhoneNumber: String)
{
// Search Via phoneNumber
let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingPhoneNumber(PhoneNumber), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey,CNContactImageData])
return FirstName, GivenName,UIImage
}
私はこれについて逆方向に進んでいるように感じますが、どちらが順方向かわかりません。
この例をすぐに実行するために、以下の情報源を使用しました。

以下のコードブロックには、承認テストが含まれています。これは、シミュレータでテストするために機能チェックを行わなければならないためです。コードはシングルビューアプリビューコントローラにすぎません。ストーリーボードのUIButtonを_findContactInfoForPhoneNumber:_メソッドに接続して、実行するかどうかを取得できます。出力はコンソールに出力されます-これらのprintステートメントを別のものに置き換える必要があります。
完全なView Controllerコードに関心がない場合は、searchForContactUsingPhoneNumber(phoneNumber: String)メソッドを確認してください。私はドキュメントでAppleのアドバイスに従い、CNContactフレームワークを非同期で実行しました。
コードは、電話番号に含まれる可能性のあるすべての_+_、_-_および_(_記号を取り除き、数字と一致するだけなので、一致させるために渡す電話番号は完全に同じでなければなりません。

正しい方法は、自分のデータベースで電話番号にインデックスを付けて、連絡先IDを検索できるようにすることです。
