Ios swift navigationAction.navigationType linkactivated未检测到相对URL

在WKWebView中，我注意到当我点击绝对url时，

navigationType

是

.linkActivated

，然而当我点击相对url时，

navigationType

是

。other

每次点击新链接时，我的应用程序都会显示一个新的视图，因此我在

webView（\uwebview:WKWebView，decisionpolicyfornavigationAction:WKNavigationAction，decisionHandler:@escaping（WKNavigationActionPolicy）

中有处理这个问题的逻辑

它适用于绝对url，因为我可以检查

.linkActivated

，但不适用于相对url，因为我不确定如何区分点击相对url与其他请求

下面是一个代码示例

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
    if self.delegate?.getCurrentViewState() != ViewState.Feed {

        if navigationAction.navigationType == .linkActivated {
            // apply logic to navigate to a new view
        }
        else if navigationAction.navigationType == .other {
            // somehow understand that this request is coming from relative url and apply same logic as above
        }

    }
    decisionHandler(.allow)
}

你们中的任何人都知道是否有办法检测我正在处理的请求是否来自相对url点击？

您可以尝试以下解决方案：

// MARK: - WKNavigationDelegate
extension NaviWebViewController {
    override func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        switch navigationAction.navigationType {
        case .linkActivated:
            linkActivated(webView: webView, navigationAction: navigationAction, decisionHandler: decisionHandler)
        default:
            otherAction(webView: webView, navigationAction: navigationAction, decisionHandler: decisionHandler)
        }
    }

    func linkActivated(webView: WKWebView, navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        guard let url = navigationAction.request.url else {
            decisionHandler(.cancel)
            return
        }
    
        guard allowLoadURL(url: url) else {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
            decisionHandler(.cancel)
            return
        }
    
        decisionHandler(.allow)
    }

    func otherAction(webView: WKWebView, navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        guard let isMainFrame = navigationAction.targetFrame?.isMainFrame, isMainFrame else {
            decisionHandler(.allow)
            return
        }
    
        guard let url = navigationAction.request.url else {
            decisionHandler(.cancel)
            return
        }
    
        guard allowLoadURL(url: url) else {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
            decisionHandler(.cancel)
            return
        }
    
        decisionHandler(.allow)
    }

    func allowLoadURL(url: URL) -> Bool {
        let domain = GlobalConstant.domain
        if let host = url.host, host.contains(domain) {
            return true
        }
    
        return false
    }
}
