将URL从ViewController 1中的UIWebView 1传递到ViewController 2中的UIWebView 2

Question

我的第一个ViewController中有UIWebView，我希望如果用户单击UIWebView 1内的任何链接，则应打开新的ViewController（例如InfoViewController）并将URL传递到InfoViewController内的新UIWebView。

我的代码：

class ViewController: UIViewController, UIWebViewDelegate {

@IBOutlet weak var webview: UIWebView!
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    let url = NSURL (string: "https://google.com");
    let requestObj = NSURLRequest(URL: url!);
    webview.delegate = self;
    webview.loadRequest(requestObj);

}

func webview(WebViewNews: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {

    if (navigationType == UIWebViewNavigationType.LinkClicked) {
    //Push to new view controller here and pass new url:
    let url = request.URL
    let infoViewController = self.storyboard?.instantiateViewControllerWithIdentifier("InfoViewController") as! InfoViewController
    infoViewController.passURL = url.absoluteString //Add passURL property in your InfoViewController

    self.navigationController!.pushViewController(infoViewController, animated: true)

    //prevent the current webview from loading the page
    return false
    }

    //webview will load first time normally/other requests will load
    return true
}

Answer 1

将webview委托设置为self：

webview.delegate = self

然后，您可以添加此委托方法。 每当尝试加载URL时，它就会运行。 您可以添加if检查，以确保它是他们单击的链接，然后运行代码以更改屏幕，并通过返回false来阻止当前的webview加载url：

//Update: got method name wrong:
func webView(webView: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {

    if (navigationType == UIWebViewNavigationType.LinkClicked {
         //Push to new view controller here and pass new url:
         let url = request.URL
         let infoViewController = self.storyboard?.instantiateViewControllerWithIdentifier("InfoViewController") as InfoViewController
         infoViewController.passURL = url.absoluteString //Add passURL property in your InfoViewController

         self.navigationController!.pushViewController(infoViewController, animated: true)

         //prevent the current webview from loading the page
         return false
    }

    //webview will load first time normally/other requests will load
    return true
}

Answer 2

1. 您需要从第一个UIWebview中拉出链接： iPhone-UIWebview-获取单击的链接的URL
2. 打开新的ViewController并传递字符串。
3. 指示您的第二个UIWebview打开URL。
