iOS9之后，通訊錄用CNContactStore實現；iOS9之前使用ABAddressBook。
基本信息設置與實現：
iOS10之后需要在plist文件中添加訪問權限：key:PRivacy - Contacts Usage Description value:contactsDesciption。mannager單例實現:
/// 單例 class var sharedInstance: YSAddressBookManager{ struct Static { static var instance : YSAddressBookManager = YSAddressBookManager() } return Static.instance }分別創建一個CNContactStore和ABAddressBook的屬性：
//注意調用ABAddressBookCreateWithOptions進行ABAddressBookCreateWithOptions的初始化需要設置為一個lazy變量，否則在用戶拒絕授權的情況下，程序將會崩潰。因為ABAddressBookCreateWithOptions(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() //獲取當前系統版本號 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據創建一個對外的權限授權狀態： //@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標注 @objc enum AddressBookAuthorizationStatus:Int { case deniedOrRestricted = 1 case authorized = 2 case notDeterMined = 3 }授權：
檢測授權情況
//檢測授權情況 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 彈出設置對話框 return .deniedOrRestricted case .authorized://已授權,加載數據 return .authorized case .notDetermined://從未進行過授權操作、請求授權 return .notDeterMined } } }請求授權
//請求授權 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：
1：//謂詞表達式判斷手機號碼是否有效 func validateMobile(_ phoneNum:String)-> Bool { if phoneNum.characters.count != 11 || phoneNum.characters.count == 0 { return false } let mobile = "^1[3|4|5|7|8][0-9]//d{8}$" let regexMobile = NSPredicate(format: "SELF MATCHES %@",mobile) let isValid:Bool = regexMobile.evaluate(with: phoneNum) if !isValid { return false } return true }2：//有的手機系統讀取到的手機號都有'-',所以去除'-' func removeUnuseChar(str:String) -> String { var tmpStr = str for char in tmpStr.characters { if char == "-" { let range = tmpStr.range(of: "-") tmpStr.removeSubrange(range!) } } return tmpStr }3： func readRecords() -> [AddressBookObj] //原始有效數據 { self.originalAddressData.removeAll() if #available(iOS 9, *){ let keysToFetch = [CNContactFormatter.descriptorForRequiredKeys(for: CNContactFormatterStyle.fullName),CNContactPhoneNumbersKey] as [Any] try! self.contact.enumerateContacts(with: CNContactFetchRequest(keysToFetch: keysToFetch as! [CNKeyDescriptor]), usingBlock: {[weak self] (contact, pointer) in var phone = "" if contact.phoneNumbers.count > 0 { let phoneNum = contact.phoneNumbers.first guard let phoneNumber = phoneNum?.value else { return } let phoneString = phoneNumber.stringValue let result = self?.removeUnuseChar(str: phoneString) if self!.validateMobile(result!) { phone = result! } if phone != "" { let obj:AddressBookObj = AddressBookObj() obj.phone = phone let name:String = String(format: "%@%@", contact.givenName,contact.familyName) obj.name = name self?.originalAddressData.append(obj) print("CNContact：/(name):/(phone)") } } }) return originalAddressData }else{ let peoples = ABAddressBookCopyArrayOfAllPeople(self.addressBook).takeRetainedValue() as [ABRecord] for people: ABRecord in peoples { var firstName = "" var lastName = "" var phone = "" if let firstNameUnmanaged = ABRecordCopyValue(people, kABPersonLastNameProperty) { firstName = firstNameUnmanaged.takeRetainedValue() as? String ?? "" } if let lastNameUnmanaged = ABRecordCopyValue(people, kABPersonFirstNameProperty) { lastName = lastNameUnmanaged.takeRetainedValue() as? String ?? "" } let phoneNums: ABMultiValue = ABRecordCopyValue(people, kABPersonPhoneProperty).takeRetainedValue() as ABMultiValue for index in 0..<ABMultiValueGetCount(phoneNums){ let label = ABMultiValueCopyValueAtIndex(phoneNums, index).takeRetainedValue() as! String let result = self.removeUnuseChar(str: label) if self.validateMobile(result) { phone = result break } } if phone != "" { let obj:AddressBookObj = AddressBookObj() obj.phone = phone let name:String = String(format: "%@%@", lastName,firstName) obj.name = name self.originalAddressData.append(obj) print("ABAddressBook：/(name):/(phone)") } } return originalAddressData } }聯系人數據的排序與使用：
//數據處理：排序、傳給后端，更新UIfunc updateOroginalData(){ //得出27個索引 let collation = UILocalizedIndexedCollation.current() let sectionTitles = collation.sectionTitles.count //self.sectionTitleArr存放section數組 self.sectionTitleArr = NSMutableArray(array: collation.sectionTitles) //初始化27個空數組 self.dataArrays存放numberOfRowsInSection var i = 0 while i<sectionTitles { let arr = NSMutableArray() self.dataArrays.add(arr) i += 1 } for obj in self.originalAddressData { if obj.name != "" { let sectionNum = collation.section(for: obj, collationStringSelector: #selector(obj.nameMethod)) let array:NSMutableArray = self.dataArrays[sectionNum] as! NSMutableArray array.add(obj) } } //對每個section中的數組按name排序 for i in 0..<self.dataArrays.count { let arr:NSMutableArray = self.dataArrays[i] as! NSMutableArray let sortArr = collation.sortedArray(from: arr as [AnyObject], collationStringSelector: #selector(getter: xxClass.name)) arr.removeAllObjects() arr.addObjects(from: sortArr) } //去掉無數據的數組 let tmpArrA = NSMutableArray() let tmpArrB = NSMutableArray() for i in 0..<self.dataArrays.count { let arr = self.dataArrays[i] if (arr as AnyObject).count == 0 { tmpArrA.add(self.sectionTitleArr[i]) tmpArrB.add(self.dataArrays[i]) } } for i in 0..<tmpArrA.count { self.sectionTitleArr.remove(tmpArrA[i]) self.dataArrays.remove(tmpArrB[i]) } tableView.reloadData()}新聞熱點
