首先你要引入两个库 在

引入之后
引入

import <ContactsUI/CNContactViewController.h>

import <ContactsUI/CNContactPickerViewController.h>

在遵循这个CNContactViewControllerDelegate,CNContactPickerDelegate,
代理
这里的代码可以直接复制直接使用很是方便

- (void)saveNewContact{
    //1.创建Contact对象，必须是可变的
    CNMutableContact *contact = [[CNMutableContact alloc] init];
    //2.为contact赋值，setValue4Contact中会给出常用值的对应关系
    [self setValue4Contact:contact existContect:NO];
    //3.创建新建好友页面
    CNContactViewController *controller = [CNContactViewController viewControllerForNewContact:contact];
    //代理内容根据自己需要实现
    controller.delegate = self;
    //4.跳转
    UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:controller];
    [self presentViewController:navigation animated:YES completion:^{
        
    }];
    
}

//保存现有联系人实现
- (void)saveExistContact{
    //1.跳转到联系人选择页面，注意这里没有使用UINavigationController
    CNContactPickerViewController *controller = [[CNContactPickerViewController alloc] init];
    controller.delegate = self;
    [self presentViewController:controller animated:YES completion:^{
        
    }];
}

- (void)contactViewController:(CNContactViewController *)viewController didCompleteWithContact:(nullable CNContact *)contact{
    [viewController dismissViewControllerAnimated:YES completion:^{
        
    }];
}

#pragma mark - CNContactPickerDelegate
//2.实现点选的代理，其他代理方法根据自己需求实现
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact{
    [picker dismissViewControllerAnimated:YES completion:^{
        //3.copy一份可写的Contact对象，不要尝试alloc一类，mutableCopy独此一家
        CNMutableContact *c = [contact mutableCopy];
        //4.为contact赋值
        [self setValue4Contact:c existContect:YES];
        //5.跳转到新建联系人页面
        CNContactViewController *controller = [CNContactViewController viewControllerForNewContact:c];
        controller.delegate = self;
        UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:controller];
        [self presentViewController:navigation animated:YES completion:^{
        }];
    }];
}


//设置要保存的contact对象
