Question

有谁知道如何使用swift中的代码（不是屏幕，因为webview很长，我们必须滚动查看所有内容）并通过{{1}分享我的所有网页视图的完整屏幕截图}？

Answer 1

加载网页视图后尝试以下代码：

已编辑：在模拟器中运行此代码，然后检查文档应用程序目录中的screenshot.jpeg文件

class ViewController: UIViewController,UIWebViewDelegate {

let fileDirectory = NSSearchPathForDirectoriesInDomains(
    .DocumentDirectory, .UserDomainMask, true)

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {


    var urlPath = "http://www.bbc.com/"
    let requestUrl = NSURL(string: urlPath)
    let request = NSURLRequest(URL: requestUrl!)
    webView.loadRequest(request)
    webView.delegate = self

}

func webViewDidFinishLoad(webView: UIWebView) {


    if (!webView.loading){

        var webViewFrame = webView.frame

        webView.frame = CGRectMake(webViewFrame.origin.x, webViewFrame.origin.y, webView.scrollView.contentSize.width, webView.scrollView.contentSize.height)

        UIGraphicsBeginImageContextWithOptions(webView.scrollView.contentSize, false, 0);
        self.webView.layer.renderInContext(UIGraphicsGetCurrentContext())
        var image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
        var imageData = UIImageJPEGRepresentation(image, 0.7)
        var currentFileName = "screenshot.jpeg"
        var imageFilePath = fileDirectory[0].stringByAppendingPathComponent(currentFileName)
        var imageFileURL = NSURL(fileURLWithPath: imageFilePath)
        imageData.writeToURL(imageFileURL!, atomically: false)
        webView.frame = webViewFrame
    }
}

}

在Swift 5中使用WKWebView解决方案

extension ViewController: WKNavigationDelegate {
    func webView(_ webView: WKWebView,didFinish navigation: WKNavigation!) {

        let configuration = WKSnapshotConfiguration()
        configuration.rect = CGRect(origin: .zero, size: (self.webView.scrollView.contentSize))

        webView.takeSnapshot(with: configuration) {image, error in
            if let image = image {
                self.saveImage(imageName: "snapshot.jpg", image: image)
            }
        }
    }
}
