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>

3.通过代码获取

//请求通讯录权限
#pragma mark 请求通讯录权限
- (void)requestContactAuthorAfterSystemVersion9{
    
    CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    if (status == CNAuthorizationStatusNotDetermined) {
        CNContactStore *store = [[CNContactStore alloc] init];
        [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError*  _Nullable error) {
            if (error) {
                NSLog(@"授权失败");
            }else {
                NSLog(@"成功授权");
            }
        }];
    }
    else if(status == CNAuthorizationStatusRestricted)
    {
        NSLog(@"用户拒绝");
        [self showAlertViewAboutNotAuthorAccessContact];
    }

        [self showAlertViewAboutNotAuthorAccessContact];
    }
    else if (status == CNAuthorizationStatusAuthorized)//已经授权
    {
        //有通讯录权限-- 进行下一步操作
        [self openContact];
    }
    
}
