UIImageView 溢出集合视图单元格

Question

UIImage 正在集合视图单元之外展开。当我向单元格添加阴影时，问题就开始了。

UI 是在代码中完成的，特别是当我将单元格上的 maskToBounds 设置为 false 时向单元格添加阴影时，图像会扩展到单元格边界之外。

    static let identifier = "kParameterCollectionViewCell"
    let bgView = UIView()
    let imageView = UIImageView()
    let nameLabel = UILabel()

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        self.clipsToBounds = true
        self.autoresizesSubviews = true
        self.backgroundColor = UIColor.clear
        self.layer.cornerRadius = 20.0
        // Add Shadows
        self.layer.shadowColor = UIColor.black.cgColor
        self.layer.shadowRadius = 1.0
        self.layer.shadowOpacity = 1.0
        self.layer.shadowOffset = CGSize(width: 5.0, height: 5.0)
        self.layer.masksToBounds = false

        bgView.frame = self.bounds
        bgView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        bgView.backgroundColor = .clear

        imageView.translatesAutoresizingMaskIntoConstraints = false
        //imageView.backgroundColor = UIColor.clear
        imageView.layer.cornerRadius = 2.0
        imageView.layer.borderColor = #colorLiteral(red: 0.2745098174, green: 0.4862745106, blue: 0.1411764771, alpha: 1)
        imageView.backgroundColor = UIColor.clear
        imageView.contentMode = .scaleAspectFill
        imageView.clipsToBounds = true
        imageView.layer.masksToBounds = true
        self.addSubview(imageView)

我希望图像视图位于单元格的最右侧。

我会尝试发布两张照片，第一张是正在发生的事情，第二张是我所期望的。

Answer 1

        imageView.contentMode = .scaleAspectFit

尝试适合方面。
