UIImageVIew keep coming forward in TableViewCell (using swift, Xcode) - ios

Question

I'm trying to build an app using UITableViewController. I set a UIImageView inside the UITableViewCell.
I've managed to show the image. But, I still can't manage the image to stay at back.
I already use command Editor >> Arrange >> Send to Back, in storyboard, but it's not working.
I also tried this code : cell.sendSubviewToBack(cell.photo)
, but still got the same problem.
can someone help me with this?
FYI, I used ParseUI SDK from parse.com
here is my whole code :
import UIKit
class TableViewController: PFQueryTableViewController, UISearchBarDelegate {
#IBOutlet var searchBar: UISearchBar!
// Initialise the PFQueryTable tableview
override init(style: UITableViewStyle, className: String!) {
super.init(style: style, className: className)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
// Configure the PFQueryTableView
self.pullToRefreshEnabled = true
self.paginationEnabled = true
}
// Define the query that will provide the data for the table view
override func queryForTable() -> PFQuery {
// Start the query object
var query = PFQuery(className: "Places")
// query with pointer
query.includeKey("mainPhoto")
// Add a where clause if there is a search criteria
if searchBar.text != "" {
query.whereKey("name", containsString: searchBar.text)
}
// Order the results
query.orderByAscending("name")
// Return the qwuery object
return query
}
//override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath, object: PFObject) -> PFTableViewCell? {
var cell = tableView.dequeueReusableCellWithIdentifier("tableCell") as! CustomTableViewCell!
if cell == nil {
cell = CustomTableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "tableCell")
}
// Extract values from the PFObject to display in the table cell
if let name = object["name"] as? String{
cell.name.text = name
}
if let detail = object["address"] as? String{
cell.detail.text = detail
}
// display initial image
var initialThumbnail = UIImage(named: "question")
cell.photo.image = initialThumbnail
cell.photo.contentMode = UIViewContentMode.Center
// extract image from pointer
if let pointer = object["mainPhoto"] as? PFObject {
if let thumbnail = pointer["photo"] as? PFFile {
cell.photo.file = thumbnail
cell.photo.loadInBackground()
cell.photo.contentMode = UIViewContentMode.ScaleAspectFill
cell.sendSubviewToBack(cell.photo)
}
}
// return the cell
return cell
}
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using [segue destinationViewController].
var detailScene = segue.destinationViewController as! DetailViewController
// Pass the selected object to the destination view controller.
if let indexPath = self.tableView.indexPathForSelectedRow() {
let row = Int(indexPath.row)
detailScene.currentObject = objects[row] as? PFObject
}
}
override func viewDidLoad(){
super.viewDidLoad()
let tapGesture = UITapGestureRecognizer(target:self, action:Selector("hideKeyboard"))
tapGesture.cancelsTouchesInView = true
// tableView.addGestureRecognizer(tapGesture)
}
func hideKeyboard(){
tableView.endEditing(true)
}
override func viewDidAppear(animated: Bool) {
// Refresh the table to ensure any data changes are displayed
tableView.reloadData()
// Delegate the search bar to this table view class
searchBar.delegate = self
}
func searchBarTextDidEndEditing(searchBar: UISearchBar) {
// Dismiss the keyboard
searchBar.resignFirstResponder()
// Force reload of table data
self.loadObjects()
}
func searchBarSearchButtonClicked(searchBar: UISearchBar) {
// Dismiss the keyboard
searchBar.resignFirstResponder()
// Force reload of table data
self.loadObjects()
}
func searchBarCancelButtonClicked(searchBar: UISearchBar) {
// Clear any search criteria
searchBar.text = ""
// Dismiss the keyboard
searchBar.resignFirstResponder()
// Force reload of table data
self.loadObjects()
}
}
