一 . 帶UI

#import <ContactsUI/ContactsUI.h>

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
    //1. 創建聯系人控制器   
 CNContactPickerViewController *contactPickerVC = [[CNContactPickerViewController alloc] init];     
  //2. 設置代理 -->獲取數據  
  contactPickerVC.delegate = self;  
  //3.模態彈出視圖 -->   
 [self presentViewController:contactPickerVC animated:true completion:nil];
}
#pragma mark - 通訊錄代理方法/**點擊取消按鈕 會調用*/- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker {    NSLog(@"cancel");}/**
選擇某個聯系人會調用 - contact頭文件中有詳細的電話信息*/
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact{
      //1. 獲取姓名
    NSLog(@"xing: %@, ming: %@",contact.familyName,contact.givenName);
     //2. 獲取電話
    //NSArray<CNLabeledValue<CNPhoneNumber *> *>   
 for (CNLabeledValue *labeledValue in contact.phoneNumbers) {    
    CNPhoneNumber *phoneNumber = labeledValue.value;      
  NSLog(@"phone: %@",phoneNumber.stringValue);
    }
}
/**選中多個聯系人的方法  -- 暫時沒什么用  這個方法如果實現  選擇單個聯系人的方法會被忽略!!!*/
- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts {   
}

二.不帶UI

#import <Contacts/Contacts.h>

- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {   
 /**    CNAuthorizationStatusNotDetermined = 0,    
   CNAuthorizationStatusRestricted,    
   CNAuthorizationStatusDenied,  
  CNAuthorizationStatusAuthorized     */   
 //1. 獲取授權狀態 
   CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];  
  //2.處理未決定狀態  
 if (status == CNAuthorizationStatusNotDetermined) {     
   [[CNContactStore new] requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {      
     //2.1 判斷授權成功          
  if (granted) {            
    //2.2 獲取數據           
     [self onGetContactInfo];    
        }else {           
     NSLog(@"授權失敗");       
     }      
  }];      
  return;   
 }   
//3 處理其他情況  
  if (status == CNAuthorizationStatusAuthorized) {    
    [self onGetContactInfo];    
    return;  
  }else {   
    NSLog(@"請在設置中打開");  
  }
}
#pragma mark - 獲取數據的方法
- (void)onGetContactInfo {   
 //二. 獲取信息  
  //1.聯系人信息抓取請求  
  //cnkey :聯系人信息是由多個屬性組成的  姓/名/電話  每個屬性都有一個字符串的key   
 CNContactFetchRequest *fetchRequest = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactGivenNameKey,CNContactFamilyNameKey,CNContactPhoneNumbersKey]];  
  //2.根據請求枚舉數據   
 CNContactStore *contactStore = [CNContactStore new];
    [contactStore enumerateContactsWithFetchRequest:fetchRequest error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {     
   NSLog(@"%@ : %@",contact.givenName,contact.familyName);  
      for (CNLabeledValue *labeledValue in contact.phoneNumbers) {     
       CNPhoneNumber *phoneNumber = labeledValue.value;      
      NSLog(@"tel: %@",phoneNumber.stringValue);      
  }   
 }];
}

附:
適配iOS8的兩個類庫- AddressBookUI.AddressBook

#import <AddressBookUI/AddressBookUI.h>

#pragma mark - 顯示聯系人界面
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {   
 //1.創建聯系人選擇導航控制器    
ABPeoplePickerNavigationController *picker = [ABPeoplePickerNavigationController new];    
//2.設置代理 - 一定不要寫delegate  
  picker.peoplePickerDelegate = self;  
  //3.模態彈出控制器   
 [self presentViewController:picker animated:true completion:nil];
}
#pragma mark - 代理方法
/**選中聯系人會調用的方法*/
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person {

    CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);

     //ABAddressBook框架,使用的是coreFoundation的語法 沒有arc ,所以遇到的Copy/alloc/create  需要釋放

    CFRelease(firstName);

}
- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {   

}
