Setting parse images to a tableView Cell - ios

Question

I'm trying to save images from Parse to a variable called image stored which I can then set to tableview cells. At the moment I just have the images from parse being saved to a PFImageView. But when I try to set these to Table View Cells I get an error : Cannot assign value of type 'PFImageView' to type 'UIImage?' . Really appreciate any help.
Here's my 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 something with the found objects
if let objects = objects as [PFObject]! {
for 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 and 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 any resources that can be 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
}
}

Answer 1

In your code you never initialize imagestored (PFImageView) but only image (UIImage). try to change in to
cell.logo!.image = self.image
I no have idea if PFImageView has any
PFImageView.image
instances, than should be UIImage() class.
Also you should have something like 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()
}
}
}

Answer 2

Try to set the image to UIImage and call do_table_refresh() at the next line
