1. 添加contact.framework和contactUI.framework以下在您的应用程序包中。

2. 添加两个文件在您的.h文件中：

   导入联系人/ Contacts.h

   进口ContactsUI/ContactsUI.h

3. 添加流动代码

   -(void)loadContactList 
   { 
   

   @try {

   CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts]; 
   
   
   if(status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusRestricted) 
   

   {

     NSLog(@"access denied"); 
   
        } 
        else 
        { 
         //Create repository objects contacts 
         CNContactStore *contactStore = [[CNContactStore alloc] init]; 
   
         //Select the contact you want to import the key attribute (https://developer.apple.com/library/watchos/documentation/Contacts/Reference/CNContact_Class/index.html#//apple_ref/doc/constant_group/Metadata_Keys) 
   
         NSArray *keys = [[NSArray alloc]initWithObjects:CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey,CNContactViewController.descriptorForRequiredKeys,nil]; 
   
         // Create a request object 
         CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:keys]; 
         request.predicate = nil; 
   
         [contactStore enumerateContactsWithFetchRequest:request 
                    error:nil 
                  usingBlock:^(CNContact* __nonnull contact, BOOL* __nonnull stop) 
         { 
          // Contact one each function block is executed whenever you get 
          NSString *phoneNumber = @""; 
          if(contact.phoneNumbers) 
           phoneNumber = [[[contact.phoneNumbers firstObject] value] stringValue]; 
   
          NSLog(@"phoneNumber = %@", phoneNumber); 
          NSLog(@"givenName = %@", contact.givenName); 
          NSLog(@"familyName = %@", contact.familyName); 
          NSLog(@"email = %@", contact.emailAddresses); 
   
   
          [contactList addObject:contact]; 
         }]; 
        } 
   
   
       } @catch (NSException *exception) { 
        NSLog(@"Exception:%@",exception.reason); 
       } 
       } 
   

调用此方法鉴于没有负载或没有视图出现。
