 PFQuery *photosFromFollowedUsersQuery = [PFQuery queryWithClassName:self.className];
 [photosFromFollowedUsersQuery whereKey:kPAPPhotoUserKey matchesKey:kPAPActivityToUserKey inQuery:followingActivitiesQuery];

 PFQuery *photosFromCurrentUserQuery = [PFQuery queryWithClassName:self.className];
 [photosFromCurrentUserQuery whereKey:kPAPPhotoUserKey equalTo:[PFUser currentUser]];
 [photosFromCurrentUserQuery whereKeyExists:kPAPPhotoPictureKey];
 
 // We create a final compound query that will find all of the photos that were
 // taken by the user's friends or by the user
 PFQuery *query = [PFQuery orQueryWithSubqueries:[NSArray arrayWithObjects:photosFromFollowedUsersQuery, photosFromCurrentUserQuery, nil]];
 [query includeKey:kPAPPhotoUserKey];
 [query orderByDescending:@"createdAt"];

Hi Khoo,

Sorry, this is outside of our support charter. We convert customer code from Parse to Backendless as a part of consulting services. If you’d like help with it, please contact sales@backendless.com.
