获取ios Swift中的所有联系人？

Question

我知道ios swift有一个Contacts Framework,我可以在其中获取联系人,但我找不到任何方法来获取所有联系人,我可以访问该数组中的每个联系人.获取联系人的所有方法似乎都需要某种条件.有什么方法可以将所有联系人聚集在一起吗？

谢谢

Answer 1

Contact Framework问题的许多答案建议迭代各种容器(帐户).但是,Apple的文档将"统一联系人"描述为

代表同一个人的不同帐户中的联系人可以自动链接在一起.链接的联系人在OS X和iOS应用程序中显示为统一联系人.统一联系人是合并到一个联系人中的一组链接联系人的内存中临时视图.

默认情况下,Contacts框架返回统一联系人.每个获取的统一联系人(CNContact)对象都有自己的唯一标识符,该标识符与链接联系人集中的任何单个联系人标识符不同.应使用其标识符重新获取统一联系人. 资源

在单个数组中获取(部分,基于键)联系人列表的最简单方法如下:

    var contacts = [CNContact]()
    let keys = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName)]
    let request = CNContactFetchRequest(keysToFetch: keys)

    do {
        try self.contactStore.enumerateContactsWithFetchRequest(request) {             
            (contact, stop) in
            // Array containing all unified contacts from everywhere
            contacts.append(contact)
        }
    } 
    catch {
        print("unable to fetch contacts")
    }

Swift 4.我创建了PhoneContacts类.请将NSContactsUsageDescription键添加到info.plist文件中

 import Foundation
 import ContactsUI

class PhoneContacts {

    class func getContacts(filter: ContactsFilter = .none) -> [CNContact] { //  ContactsFilter is Enum find it below

        let contactStore = CNContactStore()
        let keysToFetch = [
            CNContactFormatter.descriptorForRequiredKeys(for: .fullName),
            CNContactPhoneNumbersKey,
            CNContactEmailAddressesKey,
            CNContactThumbnailImageDataKey] as [Any]

        var allContainers: [CNContainer] = []
        do {
            allContainers = try contactStore.containers(matching: nil)
        } catch {
            print("Error fetching containers")
        }

        var results: [CNContact] = []

        for container in allContainers {
            let fetchPredicate = CNContact.predicateForContactsInContainer(withIdentifier: container.identifier)

            do {
                let containerResults = try contactStore.unifiedContacts(matching: fetchPredicate, keysToFetch: keysToFetch as! [CNKeyDescriptor])
                results.append(contentsOf: containerResults)
            } catch {
                print("Error fetching containers")
            }
        }
        return results
    }
}

在另一个类中调用上面的方法

import ContactsUI
func phoneNumberWithContryCode() -> [String] {

    let contacts = PhoneContacts.getContacts() // here calling the getContacts methods
    var arrPhoneNumbers = [String]()
    for contact in contacts {
        for ContctNumVar: CNLabeledValue in contact.phoneNumbers {
            if let fulMobNumVar  = ContctNumVar.value as? CNPhoneNumber {
                //let countryCode = fulMobNumVar.value(forKey: "countryCode") get country code
                   if let MccNamVar = fulMobNumVar.value(forKey: "digits") as? String {
                        arrPhoneNumbers.append(MccNamVar)
                }
            }
        }
    }
    return arrPhoneNumbers // here array has all contact numbers.
}

现在,获取联系人的电子邮件和电话

    enum ContactsFilter {
        case none
        case mail
        case message
    }

    var phoneContacts = [PhoneContact]() // array of PhoneContact(It is model find it below) 
    var filter: ContactsFilter = .none

    self.loadContacts(filter: filter) // Calling loadContacts methods

       fileprivate func loadContacts(filter: ContactsFilter) {
            phoneContacts.removeAll()
            var allContacts = [PhoneContact]()
            for contact in PhoneContacts.getContacts(filter: filter) {
                allContacts.append(PhoneContact(contact: contact))
            }

            var filterdArray = [PhoneContact]()
            if self.filter == .mail {
                filterdArray = allContacts.filter({ $0.email.count > 0 }) // getting all email 
            } else if self.filter == .message {
                filterdArray = allContacts.filter({ $0.phoneNumber.count > 0 })
            } else {
                filterdArray = allContacts
            }
            phoneContacts.append(contentsOf: filterdArray)

  for contact in phoneContacts {
      print("Name -> \(contact.name)")
      print("Email -> \(contact.email)")
      print("Phone Number -> \(contact.phoneNumber)")
    }
    let arrayCode  = self.phoneNumberWithContryCode()
    for codes in arrayCode {
      print(codes)
    }
     DispatchQueue.main.async {
       self.tableView.reloadData() // update your tableView having phoneContacts array
              }
            }
        }

PhoneContact模型类

import Foundation
import ContactsUI

class PhoneContact: NSObject {

    var name: String?
    var avatarData: Data?
    var phoneNumber: [String] = [String]()
    var email: [String] = [String]()
    var isSelected: Bool = false
    var isInvited = false

    init(contact: CNContact) {
        name        = contact.givenName + " " + contact.familyName
        avatarData  = contact.thumbnailImageData
        for phone in contact.phoneNumbers {
            phoneNumber.append(phone.value.stringValue)
        }
        for mail in contact.emailAddresses {
            email.append(mail.value as String)
        }
    }

    override init() {
        super.init()
    }
}

Swift 4的更新

let contactStore = CNContactStore()
var contacts = [CNContact]()
let keys = [
        CNContactFormatter.descriptorForRequiredKeys(for: .fullName),
                CNContactPhoneNumbersKey,
                CNContactEmailAddressesKey
        ] as [Any]
let request = CNContactFetchRequest(keysToFetch: keys as! [CNKeyDescriptor])
do {
    try contactStore.enumerateContacts(with: request){
            (contact, stop) in
        // Array containing all unified contacts from everywhere
        contacts.append(contact)
        for phoneNumber in contact.phoneNumbers {
            if let number = phoneNumber.value as? CNPhoneNumber, let label = phoneNumber.label {
                let localizedLabel = CNLabeledValue<CNPhoneNumber>.localizedString(forLabel: label)
                print("\(contact.givenName) \(contact.familyName) tel:\(localizedLabel) -- \(number.stringValue), email: \(contact.emailAddresses)")
            }
        }
    }
    print(contacts)
} catch {
    print("unable to fetch contacts")
}

Answer 4

    // You may add more "keys" to fetch referred to official documentation
    let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName)]

    // The container means 
    // that the source the contacts from, such as Exchange and iCloud
    var allContainers: [CNContainer] = []
    do {
        allContainers = try store.containersMatchingPredicate(nil)
    } catch {
        print("Error fetching containers")
    }

    var contacts: [CNContact] = []

    // Loop the containers
    for container in allContainers {
        let fetchPredicate = CNContact.predicateForContactsInContainerWithIdentifier(container.identifier)

        do {
            let containerResults = try store.unifiedContactsMatchingPredicate(fetchPredicate, keysToFetch: keysToFetch)
            // Put them into "contacts"
            contacts.appendContentsOf(containerResults)
        } catch {
            print("Error fetching results for container")
        }
    }

Answer 5

一种Swift 4.0实现，用于引入所有联系人。

let contactStore = CNContactStore()
var contacts = [CNContact]()
let keys = [CNContactFormatter.descriptorForRequiredKeys(for: .fullName)]
let request = CNContactFetchRequest(keysToFetch: keys)

do {
    try contactStore.enumerateContacts(with: request) { (contact, stop) in
        contacts.append(contact)
    }
} catch {
    print(error.localizedDescription)
}

这将创建一个本地属性来存储联系人，然后通过枚举来填充联系人contactStore。
