Objective c Objective C使用两个类解析查询结果，其中等于

我目前在objective c中有一个解析查询，它使用一个类（Photo）来检索数据

PFQuery *photosFromUsersQuery = [PFQuery queryWithClassName:@"photo"];
[photosFromUsersQuery whereKeyDoesNotExist:@"type"];
[photosFromUsersQuery whereKeyExists:kESPhotoPictureKey];
[photosFromUsersQuery whereKey:@"createdAt" greaterThanOrEqualTo:sevenDaysAgo];

PFQuery *videosFromUserQuery = [PFQuery queryWithClassName:self.parseClassName];
[videosFromUserQuery whereKeyExists:@"type"];
[videosFromUserQuery whereKey:@"createdAt" greaterThanOrEqualTo:sevenDaysAgo];

PFQuery *query = [PFQuery orQueryWithSubqueries:[NSArray arrayWithObjects:photosFromUsersQuery, videosFromUserQuery, nil]];

[query includeKey:kESPhotoUserKey];
[query orderByDescending:@"createdAt"];

现在我需要使用第二个类（user），它是两个类中的指针。
我想从上面的查询中筛选数据，以便只显示用户具有公共配置文件的数据。
在user类中，我有一个名为privacy的列，其中包含Public或Private的值。

我尝试过很多方法，但都没有成功。
请帮我完成这项任务

我想您正在寻找matchesQuery选项。我没有做太多的objc，但它应该看起来像这样

PFQuery *photosFromUsersQuery = [PFQuery queryWithClassName:@"photo"];
[photosFromUsersQuery whereKeyDoesNotExist:@"type"];
[photosFromUsersQuery whereKeyExists:kESPhotoPictureKey];
[photosFromUsersQuery whereKey:@"createdAt" greaterThanOrEqualTo:sevenDaysAgo];

PFQuery *videosFromUserQuery = [PFQuery queryWithClassName:self.parseClassName];
[videosFromUserQuery whereKeyExists:@"type"];
[videosFromUserQuery whereKey:@"createdAt" greaterThanOrEqualTo:sevenDaysAgo];

PFQuery *query = [PFQuery orQueryWithSubqueries:[NSArray arrayWithObjects:photosFromUsersQuery, videosFromUserQuery, nil]];

PFQuery *userQuery = [PFQuery queryWithClassName:@"User"]
[userQuery whereKey:@"privacy" equalTo:@"Public"]
[query whereKey:@kESPhotoUserKey matchesQuery: userQuery]
[query orderByDescending:@"createdAt"];

这返回了零个结果。这返回了零个结果。
