获取手机通讯录，分为两种方式，一是跳转到系统的UI视图上进行选择，这种方式是不需要添加权限的，二是，自定义视图选择，这个是需要添加权限的。主要框架是

-系统UI

#import <Contacts/CNContact.h>
#import <ContactsUI/ContactsUI.h>

我这里是使用跳转到系统UI选择联系人，分别讲述OC和Swift的实现方法。

OC的实现方式

导入头文件，引入代理，定义一个数组，接收数据

#import <Contacts/CNContact.h>
#import <ContactsUI/ContactsUI.h>
@interface ViewController ()<CNContactPickerDelegate,CNContactViewControllerDelegate>

@property (nonatomic, strong) NSMutableArray *dateArray;

@end

创建系统UI视图，签署代理，跳转系统UI

- (void)viewDidLoad {
[super viewDidLoad];
_dateArray = [[NSMutableArray alloc] init];
CNContactPickerViewController *nav = [[CNContactPickerViewController alloc] init];
nav.delegate = self;
[self presentViewController:nav animated:YES completion:nil];

[CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
}

取消调用的代理方法 可不写，取消时，自动dismiss

- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker{

}

完成调用的方法 遍历所选中的联系人，定义一个字典，存储需要的数据，然后加到dateArray中

 - (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact*> *)contacts{
for (CNContact *cont in contacts) {
    NSMutableDictionary *userDic = [[NSMutableDictionary alloc] init];
    //名字
    NSString *name = @"";
    if (cont.familyName) {
        name = [NSString stringWithFormat:@"%@",cont.familyName];
    }
    if (cont.givenName) {
        name = [NSString stringWithFormat:@"%@%@",name,cont.givenName];
    }
    [userDic setObject:name forKey:@"name"];
    if (cont.organizationName) {
        
        [userDic setObject:cont.organizationName forKey:@"organizationName"];
    }
    if (cont.imageData) {
        [userDic setObject:[UIImage imageWithData:cont.imageData] forKey:@"image"];
    }
    if (cont.phoneNumbers) {
  
        for (CNLabeledValue *labeValue in cont.phoneNumbers) {
            CNPhoneNumber *phoneNumber = labeValue.value;
            NSString *phone = [[phoneNumber.stringValue componentsSeparatedByString:@"-"] componentsJoinedByString:@""];
            if (phone.length == 11) {
                [userDic setObject:phone forKey:@"phone"];
            }
        }
        
    }
    [_dateArray addObject:userDic];
    
    
}

}

Swift的实现方式

导入头文件，引入代理，定义一个数组，接收数据

import ContactsUI
class ViewController: UIViewController ,CNContactPickerDelegate,CNContactViewControllerDelegate{

var dateArray : Array<Dictionary<String,Any>>?;

创建系统UI视图，签署代理，跳转系统UI

override func viewDidLoad() {
    super.viewDidLoad()
    dateArray = Array.init();
    let contUI = CNContactPickerViewController.init();
    contUI.delegate = self;
    self.present(contUI, animated: true, completion: nil);
    CNContactStore.authorizationStatus(for: CNEntityType.contacts);
    
}

//取消的代理方法

func contactPickerDidCancel(_ picker: CNContactPickerViewController) {
    
}

//完成的代理方法

 func contactPicker(_ picker: CNContactPickerViewController, didSelect contacts: [CNContact]) {
    for cont in contacts {
        var userDic:Dictionary<String,Any> = Dictionary();
        
       let name = String.init(format: "%@%@", cont.familyName,cont.givenName);
        userDic["name"] = name;
        let organ = cont.organizationName;
        if cont.imageData != nil{
            let img = UIImage.init(data: cont.imageData!);
            userDic["image"] = img;
        }
        userDic["organ"] = organ;
        
        dateArray?.append(userDic);
    }
    
    

}

获取系统通讯录全部信息-Swift

通讯录权限 Privacy - Contacts Usage Description

引入import Contacts

创建通讯录

 //创建通讯录
func contacts(){
    //创建通讯录
    let store = CNContactStore.init();
    //获取授权状态
    let AuthStatus = CNContactStore.authorizationStatus(for: CNEntityType.contacts);
    
    //没有授权
    if AuthStatus == CNAuthorizationStatus.notDetermined{
        
        //用户授权
        store.requestAccess(for: CNEntityType.contacts, completionHandler: { (isLgranted, error) in
            if isLgranted == true{
                print("授权成功");
                self.getPhoneList();
            }else{
                print("授权失败");
            }
            
        });
        
    }else{
        getPhoneList();
    }

}

获取通讯录

//获取通讯录
func getPhoneList(){
    //创建通讯录
    let store = CNContactStore.init();
    //获取授权状态
    let AuthStatus = CNContactStore.authorizationStatus(for: CNEntityType.contacts);

    if AuthStatus == CNAuthorizationStatus.authorized{
        
        //获取所有的联系人
        let keys = [CNContactGivenNameKey,CNContactFamilyNameKey,CNContactPhoneNumbersKey];
        let request = CNContactFetchRequest.init(keysToFetch: keys as [CNKeyDescriptor]);
        try?store.enumerateContacts(with: request, usingBlock: { (contact, iStop) in
         
            //姓
            let firstName = contact.familyName;
            //名
            let lastName = contact.givenName;
           print(firstName,lastName);
            let phoneArr = contact.phoneNumbers;
            var phonetextArr:Array<String> = Array.init();
            for labelValue in phoneArr{
                let cnlabelV = labelValue as CNLabeledValue;
                let value = cnlabelV.value;
                
                let phoneValue = value.stringValue;
                let phoneLabel = cnlabelV.label;
                print(phoneLabel,phoneValue);
            }
      
        });
      
    }

}

}

注意

在笔者的测试过程中，iStop返回的一直是false，OC里面返回的也一直是NO
如何判断读取完成呢？

 try?store.enumerateContacts(with: request, usingBlock: { (contact, iStop) in{

    });

经过测试发现，上面那个方法，是阻塞当前线程的，所以在那个方法之后，再做自己需要的操作。
