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。
文档
Demo效果
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
- 让ViewController实现CNContactPickerDelegate协议
实现如下方法，处理选中的结果
@H_404_113@
- CNContactFormatter
- CNPostalAddressFormatter
- CNContact.localizedStringForKey
- CNLabeledValue.localizedStringForLabel
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 来查询
- unifiedContactsMatchingPredicate:keysToFetch:error:
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
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
