如何在Xcode-Swift中以编程方式命名从UIBezierPath()中提取的UIImage？

import UIKit

func createNamedImage(from path: UIBezierPath, withName name: String) -> UIImage? {
    // 开始图形上下文
    UIGraphicsBeginImageContextWithOptions(path.bounds.size, false, 0.0)
    guard let context = UIGraphicsGetCurrentContext() else { return nil }
    
    // 将路径添加到上下文并填充颜色
    UIColor.blue.setFill()
    path.fill()
    
    // 从当前图形上下文中获取UIImage
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    
    // 保存图像到应用的文档目录，并为其命名
    if let image = image {
        saveImage(image, withName: name)
    }
    
    return image
}

func saveImage(_ image: UIImage, withName name: String) {
    // 获取应用的文档目录路径
    guard let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first else { return }
    
    // 创建完整的文件路径
    let fileName = "\(name).png"
    let fileURL = documentsDirectory.appendingPathComponent(fileName)
    
    // 将UIImage转换为PNG格式并保存到文件
    if let data = image.pngData() {
        try? data.write(to: fileURL)
    }
}

// 使用示例
let path = UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: 100, height: 100))
if let image = createNamedImage(from: path, withName: "myCustomImage") {
    // 使用image
}
