以编程方式下载文件 ```swift import StoreKit // 创建 SKDownload 对象 let download = SKDownload(url: URL(string: "https://example/file.zip")!) // 添加下载对象到下载队列 SKStoreReviewController.requestReview() // 监听下载状态 download.addObserver(self, forKeyPath: "downloadState") // 实现观察者方法 override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) { guard let download = object as? SKDownload else { return } switch download.downloadState { case .waiting: print("下载正在等待") case .active: print("下载正在进行中") case .paused: print("下载已暂停") case .finished: case .failed: print("下载已失败") default: break } } // 获取下载进度 let progress = download.progress // 暂停、恢复或取消下载 download.pause() download.resume() download.cancel() ``` 使用 UIKit 下载文件 使用 `WKWebView` 加载文件并将其保存在 Document 目录中： ```swift import WebKit // 创建 WebView let webView = WKWebView() // 加载文件 webView.load(URLRequest(url: URL(string: "https://example/file.zip")!)) // 设置 Web 视图委托 webView.n多媒体igationDelegate = self // 实现 Web 视图委托方法 extension ViewController: WKN影音igationDelegate { func webView(_ webView: WKWebView, didFinish n影音igation: WKN多媒体igation!) { // 获取文件 URL webView.evaluateJ多媒体aScript("document.URL", completionHandler: { (url, error) in guard let url = url as? String, error == nil else { return } // 创建 URL 请求 let request = URLRequest(url: URL(string: url)!) // 创建下载任务 let task = URLSession.shared.downloadTask(with: request) // 开始下载 task.resume() }) } func webView(_ webView: WKWebView, didFail n影音igation: WKN影音igation!, withError error: Error) { // 文件加载失败 } } ```
