获取 - 通过 UIWebView SWIFT 来自 URL 的响应

Question

我正在尝试学习 IOS 编程，真正的第一步，但找不到 Swift 我的问题的完整 class 代码示例。正在加载网页，但我从未收到响应。这显然是 "extension" 部分的东西，我可能不需要委托

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
    }
}

我从来没有收到第二个 NSLog 的消息

将您的代码修改为

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
    }
}
