Get - response from URL via UIWebView SWIFT - ios

Question

I'm trying to learn IOS programming, really first steps, and can't find Swift Examples for my issue with a complete class code.
The Web page is being loaded, but I never get a response.
It's obviously something with "extension" part and I probably don't need delegate
import UIKit
class VkLoginViewController: UIViewController {
#IBOutlet weak var webView: UIWebView!
var delegate:UIWebViewDelegate!
override func viewDidLoad() {
super.viewDidLoad()
let link = String.localizedStringWithFormat("http://api.vk.com/oauth/authorize?client_id=%#&scope=email,photos,offline&redirect_uri=http://api.vk.com/blank.html&display=touch&response_type=token", Setup.VK_AUTH_SCHEME)
NSLog(link)
delegate = self
UIWebView.loadRequest(webView)(NSURLRequest(URL: NSURL(string: link)!))
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension VkLoginViewController : UIWebViewDelegate{
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
let str = request.URL?.absoluteString
NSLog(str!)
return true
}
}
I never get to second NSLog's message

Modify your code to
class VkLoginViewController: UIViewController {
#IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
let link = String.localizedStringWithFormat("http://api.vk.com/oauth/authorize?client_id=%#&scope=email,photos,offline&redirect_uri=http://api.vk.com/blank.html&display=touch&response_type=token", Setup.VK_AUTH_SCHEME)
NSLog(link)
webView.delegate = self
webView.loadRequest(webView)(NSURLRequest(URL: NSURL(string: link)!))
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
extension VkLoginViewController : UIWebViewDelegate{
func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
let str = request.URL?.absoluteString
NSLog(str!)
return true
}
}
Hope this help
