WKWebView在Safari中打开来自某些域的链接

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)

回答:

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:

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)

}

}

}
