How to use a fixed height for UIImageView in a tableViewHeader with Scale to Fill mode?

Tag : ios , By : ciops

seems to work fine iOS 6+ Using Auto Layout Table View with Header and Footer because cells in between are static (static cells are only supported in a UITableViewController, not a UITableView in a normal UIViewController..) , Fixed by checking "Clip Subviews" in IB.

Auto-Layout: Get UIImageView height to calculate cell height correctly

I think the issue was by ths following , So I think the underlying issue is a kind of chicken and egg problem.
In order to 'aspect fit' the image to the UIImageView the system needs a size for the view, and yet we would like the height of the view to be determined after aspect fitting the image given a known width for the view.
class CustomCell: UITableViewCell {

    @IBOutlet weak var imageTitle: UILabel!

    @IBOutlet weak var postedImageView: UIImageView!

    internal var aspectConstraint : NSLayoutConstraint? {
        didSet {
            if oldValue != nil {
            if aspectConstraint != nil {

    override func prepareForReuse() {
        aspectConstraint = nil

    func setPostedImage(image : UIImage) {

        let aspect = image.size.width / image.size.height

        aspectConstraint = NSLayoutConstraint(item: postedImageView, attribute: NSLayoutAttribute.Width, relatedBy: NSLayoutRelation.Equal, toItem: postedImageView, attribute: NSLayoutAttribute.Height, multiplier: aspect, constant: 0.0)

        postedImageView.image = image

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as CustomCell

        cell.imageTitle.text = titles[indexPath.row]

        let image = images[titles[indexPath.row]]!

        return cell

This might help you UITextField constraints:
Leading space, Trailing space, Top space to UIView margins constraints + Height constraint of the textfield.

like below fixes the issue Add the following constraint to the imageView:
"aspect ratio" constraint with the multiplier set to the imageView's aspect ratio.

wish help you to fix your issue Try setting thumbnail vertical compression resistance lower than title vertical hugging priority. In code it'll look like this:
    thumbnail.setContentCompressionResistancePriority(.defaultLow, for: .vertical)
    titleLabel.setContentHuggingPriority(.required, for: .vertical)
