連絡先フレームワークを使用してiOS 9ですべての連絡先レコードを取得する方法

AddressBookフレームワークの大部分はiOS 9で非推奨になりました。新しい連絡先フレームワークでは、 documentation はNSPredicateに一致するレコードを取得する方法のみを示しますが、必要な場合はallレコード？

他の両方の回答は、defaultContainerIdentifierを使用してコンテナから連絡先をロードするだけです。ユーザーが複数のコンテナ（つまり、連絡先を保存するために使用されるExchangeとiCloudアカウント）を持っているシナリオでは、これはデフォルトとして設定されたアカウントからのみ連絡先をロードします。したがって、質問の作成者が要求したall連絡先は読み込まれません。

おそらく代わりにしたいのは、すべてのコンテナを取得し、それらを反復処理して、各コンテナからすべての連絡先を抽出することです。次のコードスニペットは、Swiftのアプリの1つでそれを行う方法の例です。

lazy var contacts: [CNContact] = {
    let contactStore = CNContactStore()
    let keysToFetch = [
        CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName),
        CNContactEmailAddressesKey,
        CNContactPhoneNumbersKey,
        CNContactImageDataAvailableKey,
        CNContactThumbnailImageDataKey]

    // Get all the containers
    var allContainers: [CNContainer] = []
    do {
        allContainers = try contactStore.containersMatchingPredicate(nil)
    } catch {
        print("Error fetching containers")
    }

    var results: [CNContact] = []

    // Iterate all containers and append their contacts to our results array
    for container in allContainers {
        let fetchPredicate = CNContact.predicateForContactsInContainerWithIdentifier(container.identifier)

        do {
            let containerResults = try contactStore.unifiedContactsMatchingPredicate(fetchPredicate, keysToFetch: keysToFetch)
            results.appendContentsOf(containerResults)
        } catch {
            print("Error fetching results for container")
        }
    }

    return results
}()

Objective-C：

//ios 9+
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted == YES) {
        //keys with fetching properties
        NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
        NSString *containerId = store.defaultContainerIdentifier;
        NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
        NSError *error;
        NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
        if (error) {
            NSLog(@"error fetching contacts %@", error);
        } else {
            for (CNContact *contact in cnContacts) {
                // copy data to my custom Contacts class. 
                Contact *newContact = [[Contact alloc] init];
                newContact.firstName = contact.givenName;
                newContact.lastName = contact.familyName;
                UIImage *image = [UIImage imageWithData:contact.imageData];
                newContact.image = image;
                for (CNLabeledValue *label in contact.phoneNumbers) {
                    NSString *phone = [label.value stringValue];
                    if ([phone length] > 0) {
                        [contact.phones addObject:phone];
                    }
                }
            }
        }
    }        
}];

また、すべての連絡先を取得するには、enumerateContactsWithFetchRequestメソッドを使用できます。

CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted == YES) {
        //keys with fetching properties
        NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
        CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
        NSError *error;
        BOOL success = [store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {
            if (error) {
                NSLog(@"error fetching contacts %@", error);
            } else {
                // copy data to my custom Contact class. 
                Contact *newContact = [[Contact alloc] init];
                newContact.firstName = contact.givenName;
                newContact.lastName = contact.familyName;
                // etc.
            }
        }];
    }        
}];

名前で連絡先をフィルタリングしたい場合、これを使用できます：

Obj-C：

// keys from example above
NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
NSArray *cnContacts = [store unifiedContactsMatchingPredicate:[CNContact predicateForContactsMatchingName:@"John Appleseed"] keysToFetch:keys error:&error];

スウィフト3：

let store = CNContactStore()
let contacts = try store.unifiedContactsMatchingPredicate(CNContact.predicateForContactsMatchingName("Appleseed"), keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey])

SwiftおよびContactsフレームワークを使用して、名前と電話番号を含むすべての連絡先を取得する

import Contacts

let store = CNContactStore()
store.requestAccessForEntityType(.Contacts, completionHandler: {
    granted, error in

    guard granted else {
        let alert = UIAlertController(title: "Can't access contact", message: "Please go to Settings -> MyApp to enable contact permission", preferredStyle: .Alert)
        alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
        self.presentViewController(alert, animated: true, completion: nil)
        return
    }

    let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName), CNContactPhoneNumbersKey]
    let request = CNContactFetchRequest(keysToFetch: keysToFetch)
    var cnContacts = [CNContact]()

    do {
        try store.enumerateContactsWithFetchRequest(request){
            (contact, cursor) -> Void in
            cnContacts.append(contact)
        }
    } catch let error {
        NSLog("Fetch contact error: \(error)")
    }

    NSLog(">>>> Contact list:")
    for contact in cnContacts {
        let fullName = CNContactFormatter.stringFromContact(contact, style: .FullName) ?? "No Name"
        NSLog("\(fullName): \(contact.phoneNumbers.description)")
    }
})

連絡先の取得はslow操作であるため、メインUIスレッドをブロックしないでください。バックグラウンドスレッドでCNContactFetchRequestを実行します。そのため、コードをcompletionHandlerに配置します。バックグラウンドスレッドで実行されます。

Appleは、実際には、CNContactStoreのenumerateContactsWithFetchRequestを使用して、すべての連絡先とNOTUnifiedContactsMatchingPredicateを取得することをお勧めします。

以下は、Obj-Cの作業コードです。

CNContactStore *store = [[CNContactStore alloc] init];

//keys with fetching properties
NSArray *keys = @[CNContactGivenNameKey, CNContactPhoneNumbersKey]; 
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys];
NSError *error;

[store enumerateContactsWithFetchRequest:request error:&error usingBlock:^(CNContact * __nonnull contact, BOOL * __nonnull stop) {

        // access it this way -> contact.givenName; etc

}];

Appleが列挙関数を推奨するリンクを次に示します。 https://developer.Apple.com/reference/contacts/cncontactstore/1403266-unifiedcontactsmatchingpredicate?language=objc#discussion

リンクの有効期限が切れた場合、Appleは次のように書きました。

一致するものが見つからない場合、このメソッドは空の配列（またはエラーの場合はnil）を返します。 CNContactクラスの述語からの述語のみを使用してください。複合述語は、このメソッドではサポートされていません。統一のため、返された連絡先は、指定したものとは異なる識別子を持つ場合があります。 すべての連絡先を取得するには、enumerateContactsWithFetchRequest:error:usingBlock:を使用します。

For Swift 4

        var results: [CNContact] = []

        let fetchRequest = CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey as CNKeyDescriptor, CNContactFamilyNameKey as CNKeyDescriptor, CNContactMiddleNameKey as CNKeyDescriptor, CNContactEmailAddressesKey as CNKeyDescriptor,CNContactPhoneNumbersKey as CNKeyDescriptor])

        fetchRequest.sortOrder = CNContactSortOrder.userDefault

        let store = CNContactStore()

        do {
            try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
                print(contact.phoneNumbers.first?.value ?? "no")
                results.append(contact)

            })
        }
        catch let error as NSError {
            print(error.localizedDescription)
        }

旧バージョン for Swift var結果にはすべての連絡先が含まれます

let contactStore = CNContactStore()
    var results: [CNContact] = []
    do {
        try contactStore.enumerateContactsWithFetchRequest(CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactEmailAddressesKey,CNContactPhoneNumbersKey])) {
            (contact, cursor) -> Void in
            results.append(contact)
            }
    }
    catch{
        print("Handle the error please")

Swiftでの@rocolitisの回答！彼の答えは、Appleのドキュメントによると、これを行う最も正しい方法です。

let contactStore = CNContactStore()
let keys = [CNContactPhoneNumbersKey, CNContactFamilyNameKey, CNContactGivenNameKey, CNContactNicknameKey] as [CNKeyDescriptor]
let request = CNContactFetchRequest(keysToFetch: keys)

try? contactStore.enumerateContacts(with: request) { (contact, error) in

    // Do something with contact

}

最初に連絡先へのアクセスを確認する必要があります！

let authorization = CNContactStore.authorizationStatus(for: CNEntityType.contacts)

switch authorization {
case .authorized: break
case .denied: break
case .restricted: break
case .notDetermined: break
}

Reid

最初にデフォルトのコンテナ識別子を取得し、コンテナ識別子に一致する述語を使用します

let keysToFetch = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
let containerId = CNContactStore().defaultContainerIdentifier()
let predicate: NSPredicate = CNContact.predicateForContactsInContainerWithIdentifier(containerId)
let contacts = try CNContactStore().unifiedContactsMatchingPredicate(predicate, keysToFetch: keysToFetch)

私はこのコードを試していますが、うまくいきます。連絡先を使用して、Swift3最新の​​フレームワークでこのコードを使用して、すべての連絡先の詳細を取得できます。

let requestForContacts = CNContactFetchRequest(keysToFetch: [CNContactIdentifierKey as CNKeyDescriptor, CNContactFormatter.descriptorForRequiredKeys(for: CNContactFormatterStyle.fullName), CNContactPhoneNumbersKey as CNKeyDescriptor ,CNContactImageDataKey as CNKeyDescriptor,CNContactEmailAddressesKey as CNKeyDescriptor,CNContactBirthdayKey as CNKeyDescriptor])
do {
    try self.store.enumerateContacts(with: requestForContacts) { contact, stop in
        print("contact:\(contact)")
        self.contacts.append(contact)
    }
} catch {
    print(error)
}

for contact in self.contacts {
    print(contact)
    let firstName = contact.givenName
    nameArray.append(firstName)
    print("first:\(firstName)")
    let phoneNumber = (contact.phoneNumbers[0].value).value(forKey: "digits")
    phoneNumberArray.append(phoneNumber as! String)
    let emailAddress = contact.emailAddresses[0].value(forKey: "value")
    emailAddressArray.append(emailAddress as! String)
}

Swift 4のこのバージョンを共有したかっただけです

info.plist：

<key>NSContactsUsageDescription</key>
    <string>$(PRODUCT_NAME) requires to access your contacts ...</string>

モジュール：

import Contacts

コード：

func fetchContacts(completion: @escaping (_ result: [CNContact]) -> Void){
        DispatchQueue.main.async {
            var results = [CNContact]()
            let keys = [CNContactGivenNameKey,CNContactFamilyNameKey,CNContactMiddleNameKey,CNContactEmailAddressesKey,CNContactPhoneNumbersKey] as [CNKeyDescriptor]
            let fetchRequest = CNContactFetchRequest(keysToFetch: keys)
            fetchRequest.sortOrder = .userDefault
            let store = CNContactStore()
            store.requestAccess(for: .contacts, completionHandler: {(grant,error) in
                if grant{
                    do {
                        try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
                            results.append(contact)
                        })
                    }
                    catch let error {
                        print(error.localizedDescription)
                    }
                    completion(results)
                }else{
                    print("Error \(error?.localizedDescription ?? "")")
                }
            })
        }
    }

使用法：

fetchContacts(completion: {contacts in
            contacts.forEach({print("Name: \($0.givenName), number: \($0.phoneNumbers.first?.value.stringValue ?? "nil")")})

最初にinfo.plistで使用情報を記述する必要があります。ユーザーが連絡先へのアクセスを許可し、キー（取得する必要がある値）を定義したかどうかを確認するチェックを追加しました。前の回答の1つで述べたように、それは時間がかかるプロセスなので、バックグラウンド処理のためにDispatchQueueを追加し、連絡先配列を呼び出し元に返すために完了ハンドラーを追加しました。

現在、iOS9 ABAddressBookRefは廃止されているため、電話からすべての連絡先を取得するには、このフレームワークを使用してこの関数を追加し、連絡先の配列を取得します。

このような.hクラスの連絡先フレームワークをインポートする

#import <Contacts/Contacts.h>

次に、このメソッドを.mファイルに追加します

 -(void)contactsFromAddressBook{
//ios 9+
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted == YES) {
        //keys with fetching properties
        NSArray *keys = @[CNContactFamilyNameKey, CNContactGivenNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey];
        NSString *containerId = store.defaultContainerIdentifier;
        NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
        NSError *error;
        NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
        if (error) {
            NSLog(@"error fetching contacts %@", error);
        } else {
            NSString *phone;
            NSString *fullName;
            NSString *firstName;
            NSString *lastName;
            UIImage *profileImage;
            NSMutableArray *contactNumbersArray;
            for (CNContact *contact in cnContacts) {
                // copy data to my custom Contacts class.
                firstName = contact.givenName;
                lastName = contact.familyName;
                if (lastName == nil) {
                    fullName=[NSString stringWithFormat:@"%@",firstName];
                }else if (firstName == nil){
                    fullName=[NSString stringWithFormat:@"%@",lastName];
                }
                else{
                    fullName=[NSString stringWithFormat:@"%@ %@",firstName,lastName];
                }
                UIImage *image = [UIImage imageWithData:contact.imageData];
                if (image != nil) {
                    profileImage = image;
                }else{
                    profileImage = [UIImage imageNamed:@"person-icon.png"];
                }
                for (CNLabeledValue *label in contact.phoneNumbers) {
                    phone = [label.value stringValue];
                    if ([phone length] > 0) {
                        [contactNumbersArray addObject:phone];
                    }
                }
                NSDictionary* personDict = [[NSDictionary alloc] initWithObjectsAndKeys: fullName,@"fullName",profileImage,@"userImage",phone,@"PhoneNumbers", nil];
                [MutableArray__Contact addObject:personDict];
            }
            dispatch_async(dispatch_get_main_queue(), ^
            {
                NSLog(@"%@",ar_Contact);
                //[self.tableViewRef reloadData];
            });
        }
    }
}];
}

このメソッドを使用して、contactsFromAddressBook関数を呼び出します

[self contactsFromAddressBook];
