如何使用swift同时模糊多个对象

import CoreImage

let filter = CIFilter(name: "CIGaussianBlur")

let inputImage = CIImage(image: yourImage)
filter?.setValue(inputImage, forKey: kCIInputImageKey)

filter?.setValue(10, forKey: kCIInputRadiusKey) // 设置模糊半径为10

if let outputImage = filter?.outputImage {
    // 处理模糊后的图像
}

let context = CIContext()
if let outputImage = filter?.outputImage,
   let cgImage = context.createCGImage(outputImage, from: outputImage.extent) {
    let blurredImage = UIImage(cgImage: cgImage)
    // 在屏幕上显示或保存到文件中
}
