Can't get corner radius to work - ios

Question

Hi Im programming an chat app and i wan't the profile pictures to have a corner radius. This is my code. Btw Im using Parse as backend.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
var imageView = PFImageView()
let user = self.users[indexPath.row]
imageView.layer.cornerRadius = imageView.frame.size.width / 2
imageView.layer.masksToBounds = true
imageView.file = user[PF_USER_PICTURE] as? PFFile
cell.textLabel?.text = user[PF_USER_FULLNAME] as? String
cell.textLabel?.font = UIFont.boldSystemFontOfSize(24)
cell.imageView?.image = imageView.image
return cell
}
UPDATE:
The problem was that my cell.imageview did not have a frame.
Thanks for the answer Max K!

Answer 1

var imageView = PFImageView()
is a different image view than:
cell.imageView?.image = imageView.image
What shows on screen is the image view of your cell not this instance of PFImageView. If you want to have PFImageView in as a class of your's cell's image view you need to set that, either in the storyboard or by subclassing your cell.

Answer 2

You applied cornerRadius to layer of imageView created here:
var imageView = PFImageView()
But then you are using only its image property and assigning it to cell`s imageView:
cell.imageView?.image = imageView.image
Apply cornerRadius to cell's imageView.

Answer 3

You are setting cornerRadius on imageView that is not added to the screen later.
You have to set it on cell.imageView
if let imageView = cell.imageView {
imageView.layer.cornerRadius = imageView.frame.size.width / 2
}

Answer 4

You are adding corner to the imageView in
var imageView = PFImageView()
Instead add corner to the cell.imageView. It seems like you are using PFImageView to download image from a file. So you can modify the code like
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
var imageView = PFImageView()
let user = self.users[indexPath.row]
cell.imageView.layer.cornerRadius = imageView.frame.size.width / 2
cell.imageView.layer.masksToBounds = true
imageView.file = user[PF_USER_PICTURE] as? PFFile
cell.textLabel?.text = user[PF_USER_FULLNAME] as? String
cell.textLabel?.font = UIFont.boldSystemFontOfSize(24)
cell.imageView?.image = imageView.image
return cell
}
Or else make imageView of cell.imageView as PFImageView
