Open WebView URL in Browser

Question

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 loa

Answer 1

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
    }
}

Also you can decide what links to open in WebView and what - in browser as easy as to write target attribute in your html page like

<a href="http://www.google.com/" target="_blank">external page</a>

And use target check in the decidePolicyForNewWindowAction, menthioned above. I've placed the full answer in this question thread. Hope you can translate it to swift yourself.
