在浏览器中打开WebView URL [英] Open WebView URL in Browser

问题描述

我做了一个非常简单的Swift应用程序，加载其上有链接的网页。每当我点击链接，他们不打开。

这是我的实现：

  import Cocoa 
 import WebKit 
 
 class ViewController：NSViewController {
 
 @IBOutlet weak var webView：WebView！ 
 
 override func viewDidLoad（）{
 super.viewDidLoad（）
 let urlString =URL
 self.webView.mainFrame.loadRequest（NSURLRequest （string：urlString）！））
} 
 
 override varresentObject：AnyObject？ {
 didSet {
 //更新视图（如果已加载）。 
} 
} 
} 
  

解决方案>

首先，将 WebView 的政策委托和您的初始网址设为类别变数：

  let url = NSURL（string：http://www.google.com/）！ 
 
 // ... 
 
 override func viewDidLoad（）{
 super.viewDidLoad（）
 
 //任何其他设置后加载视图。 
 
 self.webView.policyDelegate = self 
 
 self.webView.mainFrame.loadRequest（NSURLRequest（URL：self.url））
} 
  

然后，重写代理方法拦截导航。

  override func webView（webView：WebView !, decisionPolicyForNewWindowAction actionInformation：[NSObject：AnyObject] !, request：NSURLRequest !, newFrameName frameName：String !, decisionListener listener：WebPolicyDecisionListener！）{
 println （__LINE__）//需要该方法，println用于调试
} 
 
 
 override func webView（webView：WebView !, decisionPolicyForNavigationAction actionInformation：[NSObject：AnyObject]！ ，请求：NSURLRequest !, frame：WebFrame !, decisionListener listener：WebPolicyDecisionListener！）{
如果request.URL！.absoluteString == self.url.absoluteString {//加载初始页面
 listener.use （）//在应用程序中加载页面
} else {//所有其​​他链接
 NSWorkspace.sharedWorkspace（）。openURL（request.URL！）//使用户离开应用程序其默认浏览器
} 
} 
  

I made a very simple Swift application that loads a webpage with links on it. Whenever I click the links, they do not open. How would I got about having the links on the loaded .html webpage open in a browser window for OS X?

Here is my implementation:

import Cocoa
import WebKit

class ViewController: NSViewController {

    @IBOutlet weak var webView: WebView!

    override func viewDidLoad() {
        super.viewDidLoad()
        let urlString = "URL"
        self.webView.mainFrame.loadRequest(NSURLRequest(URL: NSURL(string: urlString)!))
    }

    override var representedObject: AnyObject? {
        didSet {
            // Update the view, if already loaded.
        }
    }
}

解决方案

First, set your WebView's policy delegate and your initial URL as a class variable:

let url = NSURL(string: "http://www.google.com/")!

// ...

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    self.webView.policyDelegate = self

    self.webView.mainFrame.loadRequest(NSURLRequest(URL: self.url))
}

Then, override the delegate methods to intercept navigation.

override func webView(webView: WebView!, decidePolicyForNewWindowAction actionInformation: [NSObject : AnyObject]!, request: NSURLRequest!, newFrameName frameName: String!, decisionListener listener: WebPolicyDecisionListener!) {
    println(__LINE__) // the method is needed, the println is for debugging
}


override func webView(webView: WebView!, decidePolicyForNavigationAction actionInformation: [NSObject : AnyObject]!, request: NSURLRequest!, frame: WebFrame!, decisionListener listener: WebPolicyDecisionListener!) {
    if request.URL!.absoluteString == self.url.absoluteString { // load the initial page
        listener.use() // load the page in the app
    } else { // all other links
        NSWorkspace.sharedWorkspace().openURL(request.URL!) // take the user out of the app and into their default browser
    }
}
