调起

eg:

//ContactsUI.framework中  
    CNContactPickerViewController *contactVC = [CNContactPickerViewController new];
    contactVC.delegate = self;
    [self presentViewController:contactVC animated:YES completion:^{

    }];

添加授权

CNContactStore *contactStore = [[CNContactStore alloc] init];
[contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
    if (granted) {
        // 成功
    } else {
        // 失败
    }
}];

代理方法

#pragma mark - CNContactViewControllerDelegate代理
//选择一个联系人的时候调用
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact{
    //1.姓名
    NSLog(@"%@-%@",contact.givenName,contact.familyName);
    //2.获取电话   --->泛型，会在遍历数组帮很大忙。
    for (CNLabeledValue *labelValue in contact.phoneNumbers) {
        NSLog(@"电话标签: %@",labelValue.label);
        CNPhoneNumber *phoneNumber = labelValue.value;
        NSLog(@"电话号码: %@",phoneNumber.stringValue);
    }

}
//实现此方法就可以选择多个联系人，如果不实现则是单选联系人
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts{
    for (CNContact *contact in contacts) {
        //1.姓名
        NSLog(@"%@-%@",contact.givenName,contact.familyName);
        //2.获取电话   --->泛型，会在遍历数组帮很大忙。
        for (CNLabeledValue *labelValue in contact.phoneNumbers) {
            NSLog(@"电话标签: %@",labelValue.label);
            CNPhoneNumber *phoneNumber = labelValue.value;
            NSLog(@"电话号码: %@",phoneNumber.stringValue);
        }
        NSLog(@"\n\n");
    }
}
//选择联系人属性
//- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty{
//    
//}
//- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperties:(NSArray<CNContactProperty *> *)contactProperties{
//    
//}
//取消选择联系人的时候调用
- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker{
