uitableview - How to change the color of a UIButton in a Table View Cell in Swift? -

i have custom tableviewcell has product name, product image, , button. in same tableviewcontroller there search bar pull specific products based on name. when search can click on button product , change color, green red , text change "original color" "changed color". works until cancel search, button reverts original form. function, if need know else let me know. in advance.

  @ibaction func changecoloraction(sender: uibutton) {      sender.backgroundcolor = uicolor.redcolor()     sender.settitle("changed color", forstate: uicontrolstate.normal)  } 

this call function:

   override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {      let cell = self.tableview.dequeuereusablecellwithidentifier("cell") as! customsearchcell      var user : useritem      if(tableview == self.searchdisplaycontroller?.searchresultstableview)     {         user = self.filteredproducts[indexpath.row]     }     else     {         user = self.productsarray[indexpath.row]     }      cell.followbutton.addtarget(self, action: "changecoloraction:", forcontrolevents: .touchupinside)      cell.configurecellwith(user)      return cell } 

when search cancelled or renewed, table rebuilds "filterdproducts" or "productsarray" arrays. have change color of button when create cell inside tableview function , store information if product "followed" or not.
