前言

Contacts.framework是苹果推出的新联系人框架。应用于iOS9.0之后，9.0之后将会全面取代iOS 9 以前的通讯录框架 AddessBook.framework。

手机通讯录iOS9前后对比 ：

| iOS9之前| 描述 | iOS9之后 |描述 |
| -------------- | -------------- | -------------- |
|AddressBook| 纯 C 语言的 API，仅仅是获得联系人数据。没有提供 UI 界面展示，需要自己搭建联系人展示界面。 | Contacts|拥有 AddressBookUI 框架的所有功能，使用起来更加的面向对象。|
| AddressBookUI |提供了联系人列表界面、联系人详情界面、添加联系人界面等，一般用于选择联系人| ContactsUI |拥有 AddressBook框架的所有功能，不再是 C 语言的 API，使用简单。|

通讯录框架ContactsUI使用

1、导入框架

#import 

2、遵循代理

代理方法：

/*!
 * @abstract Invoked when the picker is closed.
 * @discussion The picker will be dismissed automatically after a contact or property is picked.
 */
- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker;

/*!
 * @abstract Singular delegate methods.
 * @discussion These delegate methods will be invoked when the user selects a single contact or property.
 */
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact;
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty;

/*!
 * @abstract Plural delegate methods.
 * @discussion These delegate methods will be invoked when the user is done selecting multiple contacts or properties.
 * Implementing one of these methods will configure the picker for multi-selection.
 */
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray *)contacts;
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperties:(NSArray *)contactProperties;

3、授权

 CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    if (status == CNAuthorizationStatusNotDetermined) {
        [[[CNContactStore alloc] init] requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
            if (granted) {
                NSLog(@"点击同意");
                [self openContact];
            }else{
                NSLog(@"点击拒绝");
            }
        }];
    } else if (status == CNAuthorizationStatusAuthorized) {
        NSLog(@"已经授权");
        [self openContact];
    } else {
        NSLog(@"没有授权");
        UIAlertController *alert =[UIAlertController alertControllerWithTitle:@"We Need Permission To Access Your Contacts"
                                                                      message:@"Settings on iphone >Privacy>Photos>seagullstudio" preferredStyle:UIAlertControllerStyleAlert];

        [alert addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        }]];

        [alert addAction:[UIAlertAction actionWithTitle:@"Setting" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString] options:@{UIApplicationOpenSettingsURLString:@YES} completionHandler:^(BOOL success) {
                if (success) {
                    // NSLog(@"成功打开");
                } else {
                    // NSLog(@"打开失败");
                }
            }];
        }]];
        [self presentViewController:alert animated:YES completion:nil];
    }

4、获取通讯录控制器

- (void)openContact {
    CNContactPickerViewController *contactVC = [CNContactPickerViewController new];
    contactVC.delegate = self;
    [self presentViewController:contactVC animated:YES completion:nil];
}

5、实现delegate方法，获取联系人地址

#define kNULLString(string) ((![string isKindOfClass:[NSString class]])||[string isEqualToString:@""] || (string == nil) || [string isEqualToString:@""] || [string isKindOfClass:[NSNull class]]||[[string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]] length]==0)

//选择单个联系人，不展开联系人的详细信息，获取后推出CNContactPickerViewController
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact {
   [self parseAddressWithContact:contact];
   [picker dismissViewControllerAnimated:YES completion:nil];
}

-  (void)parseAddressWithContact:(CNContact *)contact {

   //contact的结构分析我贴在文章底部
    NSArray *postAddressArray = contact.postalAddresses;
    for (CNLabeledValue *addressLabel in postAddressArray) {
        CNPostalAddress *address = addressLabel.value;
        if (!kNULLString(address.street)) {
            NSLog(@"%@", address.street );
        }
        if (!kNULLString(address.city)) {
            NSLog(@"%@", address.city );
        }
        if (!kNULLString(address.postalCode)) {
            NSLog(@"%@", address.postalCode );
        }
        if (!kNULLString(address.country)) {
            NSLog(@"%@", address.country );
        }
        if (!kNULLString(address.state)) {
            NSLog(@"%@", address.state );
        }
    }

}
//取消选择的回调
- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker {
    [picker dismissViewControllerAnimated:YES completion:nil];
}
