我正在使用 ImageView 和 CollectionView 创建一个图片库。一切正常，但纵向模式图片超出限制。这是为什么？

    myPicture = UIImageView(image: myArray[0])
    view.addSubview(myPicture)
    myPicture.translatesAutoresizingMaskIntoConstraints = false
    myPicture.contentMode = .scaleAspectFill
    myPicture.topAnchor.constraint(equalTo: tabBar.bottomAnchor, constant: view.bounds.height / 80).isActive = true
    myPicture.leftAnchor.constraint(equalTo: view.leftAnchor, constant: 0).isActive = true
    myPicture.rightAnchor.constraint(equalTo: view.rightAnchor, constant: 0).isActive = true
    myPicture.bottomAnchor.constraint(equalTo: collectionView.topAnchor, constant:  0).isActive = true

在此处输入图像描述

你需要设置

myPicture.clipsToBounds = true
