Swift Displaying Parse Image in TableView Cell - ios

Question

I am attempting to display the users image that is saved to parse property "image". I have been able to display my username with no issue, but I can't seem to be able to get my image to appear. Should I be casting this information as UIImage? Am I correctly calling where the file is stored?
Here is my code:
import UIKit
class SearchUsersRegistrationViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var userArray : NSMutableArray = []
#IBOutlet var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
loadParseData()
var user = PFUser.currentUser()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func loadParseData() {
var query : PFQuery = PFUser.query()
query.findObjectsInBackgroundWithBlock {
(objects:[AnyObject]!, error:NSError!) -> Void in
if error == nil {
if let objects = objects {
println("\(objects.count) users are listed")
for object in objects {
self.userArray.addObject(object)
}
self.tableView.reloadData()
}
} else {
println("There is an error")
}
}
}
let textCellIdentifier = "Cell"
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.userArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! SearchUsersRegistrationTableViewCell
let row = indexPath.row
var individualUser = userArray[row] as! PFUser
var username = individualUser.username as String
var profilePicture = individualUser["image"] as? UIImage
cell.userImage.image = profilePicture
cell.usernameLabel.text = username
return cell
}
#IBAction func finishAddingUsers(sender: AnyObject) {
self.performSegueWithIdentifier("finishAddingUsers", sender: self)
}
}

Answer 1

The photos are saved in a PFFile and not as a UIImage..
What makes your code the following:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! SearchUsersRegistrationTableViewCell
let row = indexPath.row
var individualUser = userArray[row] as! PFUser
var username = individualUser.username as String
var pfimage = individualUser["image"] as! PFFile
pfimage.getDataInBackgroundWithBlock({
(result, error) in
cell.userImage.image = UIImage(data: result)
})
cell.usernameLabel.text = username
return cell
}

fileprivate func getImage(withCell cell: UITableViewCell, withURL url: String) {
Alamofire.request(url).responseImage { (image) in
/* Assign parsed Image */
if let parsedImage = image.data {
DispatchQueue.main.async {
/* Assign Image */
cell.imageView?.image = UIImage(data: parsedImage)
/* Update Cell Content */
cell.setNeedsLayout()
cell.layoutIfNeeded()
}
}
}
}
