電話番号で連絡先の名と姓を取得したいだけです。私はこれを試しましたが、これは遅すぎて、CPUは%120を超えています。
let contactStore = CNContactStore()
let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey]
var contacts = [CNContact]()
do {
try contactStore.enumerateContactsWithFetchRequest(CNContactFetchRequest.init(keysToFetch: keys), usingBlock: { (contact, cursor) in
if (!contact.phoneNumbers.isEmpty) {
for phoneNumber in contact.phoneNumbers {
if let phoneNumberStruct = phoneNumber.value as? CNPhoneNumber {
do {
let libPhone = try util.parseWithPhoneCarrierRegion(phoneNumberStruct.stringValue)
let phoneToCompare = try util.getNationalSignificantNumber(libPhone)
if formattedPhone == phoneToCompare {
contacts.append(contact)
}
}catch {
print(error)
}
}
}
}
})
if contacts.count > 0 {
contactName = (contacts.first?.givenName)! + " " + (contacts.first?.familyName)!
print(contactName)
completionHandler(contactName)
}
}catch {
print(error)
}
また、電話番号キットを使用して連絡先を検索すると、CPUが増加し、応答が遅くなります。
var result: [CNContact] = []
let nationalNumber = PhoneNumberKit().parseMultiple([phoneNumber])
let number = nationalNumber.first?.toNational()
print(number)
for contact in self.addressContacts {
if (!contact.phoneNumbers.isEmpty) {
let phoneNumberToCompareAgainst = number!.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).joinWithSeparator("")
for phoneNumber in contact.phoneNumbers {
if let phoneNumberStruct = phoneNumber.value as? CNPhoneNumber {
let phoneNumberString = phoneNumberStruct.stringValue
let nationalContactNumber = PhoneNumberKit().parseMultiple([phoneNumberString])
let nationalContactNumberString = nationalContactNumber.first?.toNational()
if nationalContactNumberString == number {
result.append(contact)
}
}
}
}
}
return result
実装の問題は、検索するたびにアドレス帳にアクセスすることです。
代わりに、最初のアクセス後にアドレス帳のコンテンツをメモリ内に保持する場合、この高いCPU使用率には到達しません。
まず、アドレス帳のコンテンツを保持するレイジー変数をコントローラーに保持します。
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
}()
。
func searchForContactUsingPhoneNumber(phoneNumber: String) -> [CNContact] {
var result: [CNContact] = []
for contact in self.contacts {
if (!contact.phoneNumbers.isEmpty) {
let phoneNumberToCompareAgainst = phoneNumber.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).joinWithSeparator("")
for phoneNumber in contact.phoneNumbers {
if let phoneNumberStruct = phoneNumber.value as? CNPhoneNumber {
let phoneNumberString = phoneNumberStruct.stringValue
let phoneNumberToCompare = phoneNumberString.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).joinWithSeparator("")
if phoneNumberToCompare == phoneNumberToCompareAgainst {
result.append(contact)
}
}
}
}
}
return result
}
非常に大きなアドレス帳でテストしましたが、スムーズに動作します。
これは、参照用にパッチが適用されたViewController全体です。
import UIKit
import Contacts
class ViewController: UIViewController {
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

怠惰なvar部分には floheiの答え を使用しました。
Swift 4 UPDATE
1).plistに追加
<key>NSContactsUsageDescription</key>
<string>Our application needs to your contacts</string>
2)承認をお持ちでない場合はリクエストしてください
func requestAccess() {
let store = CNContactStore()
store.requestAccess(for: .contacts) { granted, error in
guard granted else {
DispatchQueue.main.async {
self.presentSettingsActionSheet()
}
return
}
}
}
func presentSettingsActionSheet() {
let alert = UIAlertController(title: "Permission to Contacts", message: "This app needs access to contacts in order to ...", preferredStyle: .actionSheet)
alert.addAction(UIAlertAction(title: "Go to Settings", style: .default) { _ in
let url = URL(string: UIApplicationOpenSettingsURLString)!
UIApplication.shared.open(url)
})
alert.addAction(UIAlertAction(title: "Cancel", style: .cancel))
present(alert, animated: true)
}
2)以前に要求した場合は、承認ステータスを確認してください
if CNContactStore.authorizationStatus(for: .contacts) == .authorized {
getContacts()
}
3)連絡先の取得を呼び出す
var contacts = [CNContact]()
func getContacts(){
let contactStore = CNContactStore()
let keys = [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactImageDataAvailableKey, CNContactThumbnailImageDataKey]
let request = CNContactFetchRequest(keysToFetch: keys as [CNKeyDescriptor])
request.sortOrder = CNContactSortOrder.givenName
do {
try contactStore.enumerateContacts(with: request) {
(contact, stop) in
self.contacts.append(contact)
}
}
catch {
print("unable to fetch contacts")
}
}
4)これIS連絡先名を取得する関数OR番号で
func getNameFromContacts(number: String) -> String {
var contactFetched : CNContact
var contactName = ""
if contacts.count > 0 {
let numberToBeCompared = number.components(separatedBy:CharacterSet.decimalDigits.inverted).joined(separator: "")
for c in contacts {
for n in c.phoneNumbers {
if let numberRetrived = n.value as? CNPhoneNumber {
let numberRetrivedFixed = numberRetrived.stringValue.components(separatedBy:CharacterSet.decimalDigits.inverted).joined(separator: "")
if numberRetrivedFixed.elementsEqual(numberToBeCompared){
contactName = c.givenName
// OR get the contact --> c
contactFetched = c
}
}
}
}
return contactName
} else {
return ""
}
}
