ios - how to avoid reusable custom cell from overwriting data when scrolling? -

-

this code using , works fine until scroll in table view, cells overwrite each others , repostedfromlabel hidden.

func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {      let cell = tableview.dequeuereusablecellwithidentifier("feedstableviewcell", forindexpath: indexpath) as? feedstableviewcell      if (arrayofpostsfeed[indexpath.row].postedbyuser!.nickname!) != arrayofpostsfeed[indexpath.row].ownedbyuser!.nickname! {         cell!.repostedfromlabel.text! = "reposted \(self.arrayofpostsfeed[indexpath.row].postedbyuser!.nickname!)"     } else {         cell!.repostedfromlabel.hidden = true     } }

how should prevent reusable cells override each others?

you can implement prepareforreuse function in feedstableviewcell reset hidden property of repostedfromlabel. this:

override func prepareforreuse() {     self.repostedfromlabel.hidden = false }

at moment not resetting value, mixed when reusing cells.
