WKWebview加载本地html文件，深层链接进入目标页面

Question

我的应用程序中有一个WKWebview并加载本地.html文件。 我想使用深层链接重定向特定页面。 我不知道该怎么做。 你们有什么想法吗？请告诉我一个解决方案？

深层链接示例：

HELLOAPP：//index.html#/article/list/123345

码：

@property (strong, nonatomic) IBOutlet WKWebView *webView;

- (void)viewDidLoad {

    self.webView = [self.webView initWithFrame:[UIScreen mainScreen].bounds configuration:[self createWKWebApp]];
    [self.webView setNavigationDelegate:self];
    [self.webView setUIDelegate:self];
    [self.webView.configuration.preferences setValue:@YES forKey:@"allowFileAccessFromFileURLs"];
    self.webView.scrollView.bounces = NO;
    [self.webView setContentMode:UIViewContentModeScaleAspectFit];

    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"www/phoneApp"]];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:180];
    [request setHTTPMethod:@"POST"];

    [self.webView loadRequest:request];
}

Answer 1

你必须实现decidePolicyForNavigationAction的方法WKNavigationDelegate。

- (void) webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler {
    if ([navigationAction.request.URL.scheme isEqualToString:@"helloAPP"]){
        // Open app page based on the url 
        decisionHandler(WKNavigationActionPolicyCancel);
        return;
    }
    decisionHandler(WKNavigationActionPolicyAllow);
}

Answer 2

你应该在你的班级实施WKNavigationDelegate。

这是一些有用的代表。 （代表是用Swift编写的。目标C中有相同的代表。）

// MARK:- WebKit Navigation Delegate

    func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
            print("didstart called")
           //Here you can open url.
            UIApplication.shared.open((webView.url)!, options: [:], completionHandler: nil)

    }

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
            print("didFinish navigation: \(navigation)")
    }

   func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
            decisionHandler(.allow)
   }
   func webView(_ webView: WKWebView, didReceiveServerRedirectForProvisionalNavigation navigation: WKNavigation!) {
        print("didReceiveServerRedirectForProvisionalNavigation navigation: \(navigation)")
   }

    func webView(_ webView: WKWebView, didCommit navigation: WKNavigation!) {
        print("didCommit: \(navigation)")
    }
    func webView(_ webView: WKWebView, didFail navigation: WKNavigation!, withError error: Error) {
        print("loading Error: \(error)")
    }

您可以在这些函数中编写逻辑。
