ios - How to save toUser and fromUser in Parse? -

new parse backend , coding together.

looking create "favorite" function in app users can save products later tapping uibutton.

i'm trying figure out how save touser (user product post being favorited) , fromuser (user doing favoriting) in parse.

here code:

@ibaction func tagproductbutton(sender: anyobject) {          var favoritepost = pfobject(classname: "tag")         favoritepost["tagger"] = pfuser.currentuser()         favoritepost["productid"] = ??         favoritepost["usertagged"] = ??          favoritepost.saveinbackground()      } 

"tagger" = touser "usertagged" = fromuser

thank in advance! remember, i've been coding month now

you should set columns product , usertagged (from tag table) pointers if not already. don't use id string. need reference product (parse object) being tagged, code like:

    favoritepost["product"] = product     favoritepost["usertagged"] = product["user"] 

you may not need usertagged field on tag table, since user tagged attached product, may may other searches easier.
