ios 9.0后，新出了通讯录读取的api，CNContactStore，介绍下简单的使用

首先导入模块

@import Contacts;

请求权限

- (void)requestContactAuthorization {
    CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    CNContactStore *contactStore = [[CNContactStore alloc]init];
    if (status == CNAuthorizationStatusAuthorized) {
        [self loadContact];//读取操作
    }else{
        [contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
        //可以设置成功后再执行下一步操作
        if (granted){
                [self loadContact];//读取操作
            }
        }];
    }
}

读取需要使用CNContactFetchRequest进行请求

- (void)loadContact{
    CNContactStore *contactStore = [[CNContactStore alloc]init];
    NSLog(@"!!!!!!!!start date:%f",[[NSDate date] timeIntervalSince1970]*1000.0f);

    NSArray *keys = @[CNContactGivenNameKey,CNContactFamilyNameKey,CNContactPhoneNumbersKey];
    CNContactFetchRequest *request = [[CNContactFetchRequest alloc]initWithKeysToFetch:keys];
    __block NSInteger count = 0;
    [contactStore enumerateContactsWithFetchRequest:request error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
        count++;
        NSString *lastname = contact.familyName;
        NSString *firstname = contact.givenName;
        NSLog(@"%@ %@", lastname, firstname);
        
        // 2.获取联系人的电话号码
        NSArray *phoneNums = contact.phoneNumbers;
        for (CNLabeledValue *labeledValue in phoneNums) {
            // 2.1.获取电话号码的KEY
            NSString *phoneLabel = labeledValue.label;
            
            // 2.2.获取电话号码
            CNPhoneNumber *phoneNumer = labeledValue.value;
            NSString *phoneValue = phoneNumer.stringValue;
            
            NSLog(@"%@ %@", phoneLabel, phoneValue);
        }
        NSLog(@"!!!!!!!num:%ld end date:%f",(long)count,[[NSDate date] timeIntervalSince1970]*1000.0f);
        
    }];
    
}

取到的联系人对象中有各种属性

@property (readonly, copy, NS_NONATOMIC_IOSONLY) NSArray<CNLabeledValue<NSDateComponents*>*> *dates;


// Key Availability

其中很多是数组，可以在手机上试试，可以添加很多个，比如dates，会有纪念日等

切记是

NS_CLASS_AVAILABLE(10_11, 9_0)
