iOS9之后，通訊錄用CNContactStore實現(xiàn)；iOS9之前使用ABAddressBook。
基本信息設(shè)置與實現(xiàn)：
iOS10之后需要在plist文件中添加訪問權(quán)限：key:PRivacy - Contacts Usage Description value:contactsDesciption。mannager單例實現(xiàn):
/// 單例 class var sharedInstance: YSAddressBookManager{ struct Static { static var instance : YSAddressBookManager = YSAddressBookManager() } return Static.instance }分別創(chuàng)建一個CNContactStore和ABAddressBook的屬性：
//注意調(diào)用ABAddressBookCreateWithOptions進行ABAddressBookCreateWithOptions的初始化需要設(shè)置為一個lazy變量，否則在用戶拒絕授權(quán)的情況下，程序?qū)罎ⅰＲ驗锳BAddressBookCreateWithOptions(nil, nil)得到的值為nil。 lazy var addressBook:ABAddressBook = { var emptyDictionary: CFDictionary? var errorRef: Unmanaged<CFError>? let ab:ABAddressBook = ABAddressBookCreateWithOptions(emptyDictionary, &errorRef).takeRetainedValue() return ab }() @available(iOS 9.0, *) lazy var contact:CNContactStore = CNContactStore() //獲取當(dāng)前系統(tǒng)版本號 lazy var current_iOS_Version:Float = { return UIDevice.current.systemVersion.floatValue }() var originalAddressData:[AddressBookObj] = [] //用于存放通訊錄里的原始有效數(shù)據(jù)創(chuàng)建一個對外的權(quán)限授權(quán)狀態(tài)： //@objc如果是在OC和swift3混編的工程里，OC的類需要使用到AddressBookAuthorizationStatus枚舉，則加上@objc，這樣就可以在OC類里也使用，否則無需@objc標(biāo)注 @objc enum AddressBookAuthorizationStatus:Int { case deniedOrRestricted = 1 case authorized = 2 case notDeterMined = 3 }授權(quán)：
檢測授權(quán)情況
//檢測授權(quán)情況 func cheackAddressBookAuthorizationStatus()->AddressBookAuthorizationStatus { if #available(iOS 9, *) { switch CNContactStore.authorizationStatus(for: .contacts) { case .denied,.restricted: return .deniedOrRestricted case .authorized: return .authorized case .notDetermined: return .notDeterMined } }else{ switch ABAddressBookGetAuthorizationStatus() { case .denied,.restricted: //訪問限制或者拒絕 彈出設(shè)置對話框 return .deniedOrRestricted case .authorized://已授權(quán),加載數(shù)據(jù) return .authorized case .notDetermined://從未進行過授權(quán)操作、請求授權(quán) return .notDeterMined } } }請求授權(quán)
//請求授權(quán) func requestAddressBookaccess(_ success:@escaping ((_ granted:Bool )->Void)) { if #available(iOS 9, *){ self.contact.requestAccess(for: .contacts, completionHandler: { (granted, error) in if !granted { success(false) }else{ success(true) } }) }else{ ABAddressBookRequestAccessWithCompletion(self.addressBook) {(granted, error) in if !granted { success(false) }else{ success(true) } } } }讀取通訊錄信息：
