iOS获取通讯录

在不弹出通讯录控制器的情况下获取所有的通讯录信息

1.设置 info.plist 的Privacy – Contacts Usage Description

2.导入头文件

#import <Contacts/Contacts.h>

#import "ViewController.h"
#import <Contacts/Contacts.h>

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    [self requestContactAuthorAfterSystemVersion];
}

#pragma mark 请求通讯录权限

        [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError*  _Nullable error) {
            if (error) {

            } else {
