在Xib文件中使用视图层时，复制器会崩溃吗？

Question

所以我使用了xib文件并将图像视图放入该xib文件中，然后将view（perspectiveView）放入图像视图中，我想复制透视图，所以这是我在UIView文件中的代码，即xib文件类

import UIKit

class perspectiveView: UIView {


@IBOutlet var contentView: UIView!

@IBOutlet weak var perspectiveTitle: UILabel!

@IBOutlet weak var perspectiveView: UIView!

@IBOutlet weak var perspectiveImage: UIImageView!

override init(frame: CGRect) {
    super.init(frame: frame)

    commonInit()
}


override func layoutSubviews() {
    super.layoutSubviews()
    let replicatorLayer = CAReplicatorLayer()
    let coloredSquare = CALayer()
    //  coloredSquare.backgroundColor = UIColor.red.cgColor
    coloredSquare.frame = perspectiveView.bounds
    coloredSquare.contents = perspectiveView.asImage().cgImage

    let instanceCount = 3
    replicatorLayer.instanceCount = instanceCount
    replicatorLayer.instanceTransform = CATransform3DMakeTranslation(5, -10, -1)
    replicatorLayer.instanceAlphaOffset = -0.3
    replicatorLayer.addSublayer(coloredSquare)
    perspectiveView.layer.addSublayer(replicatorLayer)
}

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

    commonInit()
}


private func commonInit() {
    Bundle.main.loadNibNamed("perspectiveView", owner: self, options: nil)
    addSubview(contentView)
    contentView.frame = self.bounds
    contentView.autoresizingMask = [.flexibleHeight , .flexibleWidth]

}

}

extension UIView {
// Using a function since `var image` might conflict with an existing variable
// (like on `UIImageView`)
func asImage() -> UIImage {
    let renderer = UIGraphicsImageRenderer(bounds: bounds)
    return renderer.image { rendererContext in
        layer.render(in: rendererContext.cgContext)
    }
}
}

所以这将起作用，但不像我预期的那样
