iOS9之后，通讯录用CNContactStore实现；iOS9之前使用ABAddressBook。
基本信息设置与实现：
iOS10之后需要在plist文件中添加访问权限：key:PRivacy - Contacts Usage Description value:contactsDesciption。mannager单例实现:
/// 单例 class var sharedInstance: YSAddressBookManager{ struct Static { static var instance : YSAddressBookManager = YSAddressBookManager() } return Static.instance }分别创建一个CNContactStore和ABAddressBook的属性：
//注意调用ABAddressBookCreateWithOptions进行ABAddressBookCreateWithOptions的初始化需要设置为一个lazy变量，否则在用户拒绝授权的情况下，程序将会崩溃。因为ABAddressBookCreateWithOptions(nil, nil)得到的值为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() //获取当前系统版本号 lazy var current_iOS_Version:Float = { return UIDevice.current.systemVersion.floatValue }() var originalAddressData:[AddressBookObj] = [] //用于存放通讯录里的原始有效数据创建一个对外的权限授权状态： //@objc如果是在OC和swift3混编的工程里，OC的类需要使用到AddressBookAuthorizationStatus枚举，则加上@objc，这样就可以在OC类里也使用，否则无需@objc标注 @objc enum AddressBookAuthorizationStatus:Int { case deniedOrRestricted = 1 case authorized = 2 case notDeterMined = 3 }授权：
检测授权情况
//检测授权情况 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: //访问限制或者拒绝 弹出设置对话框 return .deniedOrRestricted case .authorized://已授权,加载数据 return .authorized case .notDetermined://从未进行过授权操作、请求授权 return .notDeterMined } } }请求授权
//请求授权 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) } } } }读取通讯录信息：
1：//谓词表达式判断手机号码是否有效 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：//有的手机系统读取到的手机号都有'-',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] //原始有效数据 { 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 } }联系人数据的排序与使用：
//数据处理：排序、传给后端，更新UIfunc updateOroginalData(){ //得出27个索引 let collation = UILocalizedIndexedCollation.current() let sectionTitles = collation.sectionTitles.count //self.sectionTitleArr存放section数组 self.sectionTitleArr = NSMutableArray(array: collation.sectionTitles) //初始化27个空数组 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) } } //对每个section中的数组按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) } //去掉无数据的数组 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()}新闻热点
