Question

我有一个UIImageView，我不希望图像触及＆＃39;视图的边缘，而不是有一些填充＆＃39;周围。但是，我尝试了以下内容，由于某些原因它没有改变：

 @IBOutlet weak var pictureOutletOne: UIImageView!

//set the image
pictureOutletOne.image = UIImage(named: itemOne)

//set the padding
pictureOutletOne.layoutMargins = UIEdgeInsetsMake(10, 10, 10, 10);

我也尝试过：

pictureOutletOne.translatesAutoresizingMaskIntoConstraints = false
pictureOutletOne.layoutMargins = UIEdgeInsets(top: 10, left: 100, bottom: 10, right: 0)

我已经阅读了很多关于此的内容，但这些是我找到的解决方案，但它们并不起作用。使用swift 3

非常感谢。

Answer 1

您可以将imageView插入视图并将约束设置为边，保证接近:)

Answer 2

Swift 4.2和5

let imageView = UIImageView()
imageView.image = UIImage(named: 
"image")?.withAlignmentRectInsets(UIEdgeInsets(top: -5, left: -5, bottom: -5, 
right: -5))

插入值应为负值

Answer 3

在新类中覆盖alignmentRectInsets属性：

    class PaddedImageView: UIImageView {
        override var alignmentRectInsets: UIEdgeInsets {
            return UIEdgeInsets(top: -10, left: -10, bottom: -10, right: -10)
        }
    }

Answer 4

let padding: CGFloat = 10    
myImageView.contentMode = .scaleAspectFill
myImageView.image = UIImage(named: "myImage.png").resizableImage(withCapInsets: UIEdgeInsets(top: padding, left: padding, bottom: padding, right: padding), resizingMode: .stretch)

在UIImageView周围填充。斯威夫特3
