将图像添加到bezierpath内的CAShapeLayer

class CustomImageView: UIImageView{ 

var bezierPath = UIBezierPath()

override func setNeedsLayout() {
    bezierPath.reversing()
    let shapeLayer = CAShapeLayer()
    shapeLayer.frame = self.bounds
    shapeLayer.path = bezierPath.cgPath
    self.layer.mask = shapeLayer
    self.layer.masksToBounds = true
}

}

您修改的代码

for wedgeNumber in 0..<numberOfWedges {
    let wedge: SpinWheelWedge = source.wedgeForSliceAtIndex(index: wedgeNumber)

    //Wedge shape
    wedge.shape.configureWedgeShape(index: wedgeNumber, radius: radius, position: spinWheelCenter, degreesPerWedge: degreesPerWedge)
    wedge.layer.addSublayer(wedge.shape)

    let imageLayer = CustomImageView()
    imageLayer.image = UIImage(named: "sample.jpg")
    imageLayer.bezierPath = wedge.shape.path
    imageLayer.setNeedsLayout()

    // Here you will get an image view with specified path 
       you can subview this imageLayer to the required view
}
