javascript - Swift - 在 WebView 中禁用链接

Question

我目前正在寻找一种方法来禁用我的 WebView 中的链接，这是我的 WebView

import UIKit

class ViewController_webView_news: UIViewController {
    @IBOutlet weak var WebViewNews: UIWebView!
    @IBOutlet weak var TBB_news: UITabBarItem!
    @IBOutlet weak var activity: UIActivityIndicatorView!
    override func viewDidLoad() {
        super.viewDidLoad()

        var TBB_news_img = UIImage(named: "TabbarNews.png") as  UIImage
        TBB_news.selectedImage = TBB_news_img
        var newsurl = "http://google.com"
        let newsViewUrl = NSURL(string: newsurl)
        let request = NSURLRequest(URL: newsViewUrl)
        WebViewNews.loadRequest(request)




    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

        }
    @IBAction func BThome(sender: AnyObject) {

        var newsurl = "http://google.com"
        let newsViewUrl = NSURL(string: newsurl)
        let request = NSURLRequest(URL: newsViewUrl)
        WebViewNews.loadRequest(request)
    }
    func webViewDidStartLoad(_ : UIWebView){activity.startAnimating()
    }
    func webViewDidFinishLoad(_ : UIWebView){activity.stopAnimating()}

有没有办法为此使用“UIWebViewNavigationType.LinkClicked”？ 目前我正在使用

let result = WebViewNews.stringByEvaluatingJavaScriptFromString("window.location.href = \"http://google.de\";")

Answer 1

使用 UIWebViewDelegate 方法并将其设置为始终返回 NO。这样它就永远不会加载任何其他 url。这是您需要将其更改为 swift 的 objective-c 代码。

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    return NO;
}

对于 swift read here

swift :

func webView(WebViewNews: UIWebView!, shouldStartLoadWithRequest request: NSURLRequest!, navigationType: UIWebViewNavigationType) -> Bool {
return false;
}
