前言:在iOS 9之前,一直使用AddressBook这个framework来访问用户通讯录。但是在iOS 9中,AddressBook被废弃了,转而使用Contacts Framework。

请求访问权限

相关类
CNContactStore(线程安全)

CNContactStore代表了实际设备上存储,通过这个类可以
- 检查当前的通讯录访问权限
- 请求访问通讯录权限
- fetch通讯录内容支持按条件fetch,和core data 类似)
- 保存到通讯录

CNContact(线程安全)

表示通讯录中一位联系人的Model类,和NSDictionary类似,他有一个子类是可变的CNMutableContact

示例代码
保存一个store对象,Demo中采用单例
注意,Swift中单例这么写是线程安全的

class ContactsStore{
   static let sharedStore = CNContactStore()
}

请求权限

let authStatus = CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts)
          let authStatus = ContactsStore.sharedStore.authorizationStatusForEntityType(CNEntityType.Contacts)
        if authStatus == CNAuthorizationStatus.Denied || authStatus == CNAuthorizationStatus.NotDetermined{
            self.contactsStore.requestAccessForEntityType(CNEntityType.Contacts,completionHandler: { (result,error) -> Void in
                    if result == false{
                        let alert = UIAlertController(title: "警告",message: "请在设置中允许通讯录访问,否则App无法正常使用",preferredStyle: UIAlertControllerStyle.Alert)
                        alert.addAction(UIAlertAction(title: "确定",style: UIAlertActionStyle.Cancel,handler: nil))
                        self.presentViewController(alert,animated: true,completion: nil)
                    }
            })
        }

调用系统的ContactsPickerViewController

  1. 让ViewController实现CNContactPickerDelegate协议
    实现如下方法,处理选中的结果
func contactPicker(picker: CNContactPickerViewController,didSelectContact contact: CNContact) {
        if let phoneNumber =  contact.phoneNumbers.first?.value as? CNPhoneNumber{
            self.textfield.text = phoneNumber.stringValue
        }
    }

然后,模态展示

let contactsVC = CNContactPickerViewController()
        contactsVC.delegate = self;
        presentViewController(contactsVC,animated:true,completion: nil)

查询全部通讯录

注意,要先指明需要fetch的属性

因为enumerateContactsWithFetchRequest这个函数会抛出异常,所以要用do-try-catch包括起来

let keys = [CNContactGivenNameKey,CNContactPhoneNumbersKey,CNContactThumbnailImageDataKey]
        let fetchAllRequest = CNContactFetchRequest(keysToFetch:keys)
        do{
            try ContactsStore.sharedStore.enumerateContactsWithFetchRequest(fetchAllRequest) { (contact,pointer) -> Void in
                self.contacts.append(contact)
            }
        }catch{

        }

条件查询

条件查询在示例工程中未列出,按照如下步骤查询
使用如下CNContact方法创建NSPredicate对象

+ predicateForContactsMatchingName:
+ predicateForContactsWithIdentifiers:
...

使用CNContactStore的
- unifiedContactsMatchingPredicate:keysToFetch:error:
查询


添加

摘自Swift2.1文档

import Contacts

// Creating a mutable object to add to the contact
let contact = CNMutableContact()

contact.imageData = NSData() // The profile picture as a NSData object

contact.givenName = "John"
contact.familyName = "Appleseed"

let homeEmail = CNLabeledValue(label:CNLabelHome,value:"john@example.com")
let workEmail = CNLabeledValue(label:CNLabelWork,value:"j.appleseed@icloud.com")
contact.emailAddresses = [homeEmail,workEmail]

contact.phoneNumbers = [CNLabeledValue(
    label:CNLabelPhoneNumberiPhone,value:CNPhoneNumber(stringValue:"(408) 555-0126"))]

let homeAddress = CNMutablePostalAddress()
homeAddress.street = "1 Infinite Loop"
homeAddress.city = "Cupertino"
homeAddress.state = "CA"
homeAddress.postalCode = "95014"
contact.postalAddresses = [CNLabeledValue(label:CNLabelHome,value:homeAddress)]

let birthday = NSDateComponents()
birthday.day = 1
birthday.month = 4
birthday.year = 1988  // You can omit the year value for a yearless birthday
contact.birthday = birthday

// Saving the newly created contact
let store = CNContactStore()
let saveRequest = CNSaveRequest()
saveRequest.addContact(contact,toContainerWithIdentifier:nil)
try store.executeSaveRequest(saveRequest)

本地化/格式化

几个常用的类

  • CNContactFormatter
  • CNPostalAddressFormatter
  • CNContact.localizedStringForKey
  • CNLabeledValue.localizedStringForLabel

举例

从Contact中拼接出全名

let fullName = CNContactFormatter.stringFromContact(contact,style: .FullName)
print(fullName)
// John Appleseed

邮政地址

let postalString = CNPostalAddressFormatter.stringFromPostalAddress(homeAddress)
print(postalString)
// 1 Infinite Loop
// Cupertino
// CA
// 95014

对通讯录的内置Key获取

let displayName = CNContact.localizedStringForKey(CNContactNicknameKey)
print(displayName)
// 昵称,在中文条件下
