WKWebView在Safari中打开来自某些域的链接

swift

在我的应用程序中,我想在WKWebView中从 我的 域(例如:communionchapelefca.org)内打开链接,然后在Safari中打开来自
其他 域(例如:google.com)的链接。我希望以编程方式执行此操作。

我已经找到了一些关于Stack溢出的解决方案,但是它们似乎都是基于Obj-C的,我正在寻找使用Swift的解决方案。

ViewController.swift:

import UIKit
import WebKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        let myWebView:WKWebView = WKWebView(frame: CGRectMake(0, 0,   UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height))

        myWebView.loadRequest(NSURLRequest(URL: NSURL(string: "http://www.communionchapelefca.org/app-home")!))

        self.view.addSubview(myWebView)

您可以实现WKNavigationDelegate,添加decidePolicyForNavigationAction方法,然后在其中检查navigationType和所请求的url。我在下面使用了
**google.com** ,但您可以将其更改为您的域:

Xcode 8.3•Swift 3.1或更高版本

import UIKit
import WebKit

class ViewController: UIViewController, WKNavigationDelegate {

    let webView = WKWebView()

    override func viewDidLoad() {
        super.viewDidLoad()

        webView.frame = view.bounds
        webView.navigationDelegate = self

        let url = URL(string: "https://www.google.com")!
        let urlRequest = URLRequest(url: url)

        webView.load(urlRequest)
        webView.autoresizingMask = [.flexibleWidth,.flexibleHeight]
        view.addSubview(webView)
    }

    func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        if navigationAction.navigationType == .linkActivated  {
            if let url = navigationAction.request.url,
                let host = url.host, !host.hasPrefix("www.google.com"),
                UIApplication.shared.canOpenURL(url) {
                UIApplication.shared.open(url)
                print(url)
                print("Redirected to browser. No need to open it locally")
                decisionHandler(.cancel)
            } else {
                print("Open it locally")
                decisionHandler(.allow)
            }
        } else {
            print("not a user click")
            decisionHandler(.allow)
        }
    }
}
