图像不适合图像视图

Question

I am making an project in swift there is an image view and I am taking an image from gallery when I set the image in the image view the image does not match with the width and height of image view. overtime the image width and height is small than the image view here is the code:

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cellIdentifier = "ImageTVCell"
        index=indexPath.row
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? ImageTVCell
       // cell?.imageView?.clipsToBounds=true
        cell?.imageView?.contentMode = UIViewContentMode.scaleAspectFit
        cell?.imageView?.image=imageArray[indexPath.row]
        return cell!
    }

Answer 1

Use .aspectfill and set clipsToBounds to true

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cellIdentifier = "ImageTVCell"
        index=indexPath.row
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? ImageTVCell
        cell?.imageView?.clipsToBounds=true
        cell?.imageView?.contentMode = UIViewContentMode.scaleAspectFill
        cell?.imageView?.image=imageArray[indexPath.row]
        return cell!
    }

Answer 2

cell?.imageView?.contentMode = UIViewContentMode.scaleAspectFit 

in your code is fitting image size in your imageview. You should use,

cell?.imageView?.contentMode = UIViewContentMode.scaleAspectFill

Also makes clipsToBounds=true.
