二，代码：
import Kingfisher
import SwiftUIstruct DetailView: View {let id: Int // 接收传递过来的 idlet destUrl = "https://baidu.com"let imageUrl = URL(string: "https://raw.gitcode.com/GitHub_Trending/ki/Kingfisher/raw/fa3609d1975791c0a6e6f75a56dc20a957967769/images/kingfisher-2.jpg")!var body: some View {VStack(spacing: 20) {Spacer()KFImage(imageUrl).fade(duration: 0.33).placeholder { ProgressView() }.resizable().scaledToFit().frame(width: 200, height: 200)// 2. 保存按钮Button(action: {saveImageToAlbum()}) {Label("保存图片到相册", systemImage: "square.and.arrow.down").padding().background(Color.blue).foregroundColor(.white).cornerRadius(10)}}.navigationTitle("详情")// SwiftUI 默认在导航跳转时提供“从右向左”的滑动动画}// 3. 保存逻辑func saveImageToAlbum() {// 从 Kingfisher 缓存中获取图片let cache = ImageCache.defaultcache.retrieveImage(forKey: imageUrl.absoluteString) { result inswitch result {case .success(let value):if let uiImage = value.image {// 调用系统方法保存到相册UIImageWriteToSavedPhotosAlbum(uiImage, nil, nil, nil)print("保存成功")} else {print("缓存中未找到图片，请确保图片已加载完毕")}case .failure(let error):print("获取缓存图片失败: \(error)")}}}
}
