ios - Setting parse images to a tableView Cell -
i'm trying save images parse variable called image stored can set tableview cells. @ moment have images parse being saved pfimageview. when try set these table view cells error : cannot assign value of type 'pfimageview' type 'uiimage?' . appreciate help.
here's code:
import uikit import parse import bolts import parseui class yourevents: uiviewcontroller, uitableviewdatasource, uitableviewdelegate { @iboutlet weak var tableview: uitableview! var currentuser = pfuser.currentuser()?.username //array var testarray = [string]() var testdecr = [string]() var image = uiimage() var imagestored = pfimageview() override func viewdidload() { super.viewdidload() var query = pfquery(classname:"companies") let pusername = pfuser.currentuser()?["username"] as? string query.wherekey("createdby", equalto:"\(pusername)") // let runkey = query.orderbyascending("companyname") query.findobjectsinbackgroundwithblock{ (objects: [pfobject]?, error: nserror?) -> void in if error == nil { //do found objects if let objects = objects [pfobject]! { object in objects { let load = object.objectforkey("companyname") as! string self.testarray .append(load) print(self.testarray) let load2 = object.objectforkey("companydescription") as! string self.testdecr.append(load2) print(self.testdecr) if let userimagefile = object["imagefile"] as? pffile { userimagefile.getdatainbackgroundwithblock { (imagedata: nsdata?, error: nserror?) -> void in if error == nil { if let imagedata = imagedata { self.image = uiimage(data:imagedata)! } } } } } } } else { //log details of failure print("error: \(error!) \(error?.userinfo) ") } } // reload uiviewcontroller , uitabkeview sleep(3) do_table_refresh() } func do_table_refresh () { dispatch_async(dispatch_get_main_queue(), { self.tableview.reloaddata() return }) } override func didreceivememorywarning() { super.didreceivememorywarning() // dispose of resources can recreated. } func numberofsectionsintableview(tableview: uitableview) -> int { return 1 } func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int { return testarray.count } func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell { let cell = tableview.dequeuereusablecellwithidentifier("yourstartups", forindexpath: indexpath) as! yourstartupscell cell.lbtitle!.text = self.testarray[indexpath.row] cell.lbdescription!.text = self.testdecr[indexpath.row] cell.logo!.image = self.imagestored return cell } } 
in code never initialize imagestored (pfimageview) image (uiimage). try change in
cell.logo!.image = self.image i no have idea if pfimageview has
pfimageview.image instances, should uiimage() class.
also should have this:
if let userimagefile = object["imagefile"] as? pffile { userimagefile.getdatainbackgroundwithblock { (imagedata: nsdata?, error: nserror?) -> void in if error == nil { if let imagedata = imagedata { self.image = uiimage(data:imagedata)! var img = uiimage(data:imagedata) image.append(img) self.tableview.reloaddata() } } }
