Swift: set Image to Custom cell ImageView - ios

Question

i want to set the Image to Custom cell. I am confuse how to do this.
lets say I have a custom cell in my UITable View.
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("CustomCellOne", forIndexPath: indexPath) as! CustomOneCell
let tapGestureRecognizer = UITapGestureRecognizer(target:self, action:#selector(imageTapped(img:)))
cell.imageView.isUserInteractionEnabled = true
cell.imageView.addGestureRecognizer(tapGestureRecognizer)
return cell
}
Now as soon as i tap in the Image the following function gets called:
func imageTapped(img: AnyObject){
print("Image clicked.")
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
let imageData: NSData = UIImagePNGRepresentation(myImage)
let image: UIImage = UIImage(data:imageData,scale:1.0)
print(image)
//i am uploading the photo from here. and i want to set this picture to my cell imageView.
}
dismissViewControllerAnimated(true, completion: nil
}
I am confused how to call the cell imageview from here??
How can i further procced?? I just need to set That obtained image to imgeView in cell other everything works fine..

Here's an example I have just tested
I have a custom TableViewCell, named ImageTableViewCell, which contains a single UIImageView, named customImageView
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: "cellImage", for: indexPath) as! ImageTableViewCell
// initialising with some dummy data of mine
cell.customImageView.image = UIImage(named: "Image\(indexPath.row).png")
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(self.imageTapped(_:)))
cell.addGestureRecognizer(tapGesture)
return cell
}
and then in the ViewController
func imageTapped(_ sender: UITapGestureRecognizer)
{
let myCell = sender.view as! ImageTableViewCell
myCell.customImageView.image = UIImage(named: "imageTapped.jpg")
}
This should update the image immediately, without any requirement to reload the table
