我正在尝试从Swift WKWebView打开UPI应用程序。
我已经尝试过使用添加openURL到其他应用程序，如果它不是http或https。
这是我遵循的策略。AppDelegate类

import Foundation
import UIKit
class AppDelegate: NSObject, UIApplicationDelegate {
    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey: Any] = [:]) -> Bool {
        return true
    }
}

下面是Webview导航委托函数

func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
        currentWebView = webView
        
        guard let url = navigationAction.request.url else {
            decisionHandler(.allow)
            return
        }
        
        print("NavAction URL: \(url)")
        
        if navigationAction.targetFrame == nil {
            // Open in the same tab if the target frame is nil (new tab)
            print("NavAction 1")
            currentWebView?.load(navigationAction.request)
            decisionHandler(.cancel)
            return
        }
        
        else if let url = navigationAction.request.url,
           !url.absoluteString.hasPrefix("http://"),
           !url.absoluteString.hasPrefix("https://"),
           UIApplication.shared.canOpenURL(url) {
            
            // Have UIApplication handle the url (sms:, tel:, mailto:, ...)
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
            
            // Cancel the request (handled by UIApplication).
            decisionHandler(.cancel)
        }
        
        decisionHandler(.allow)
    }

我如何才能打开UPI应用程序的方式Safari打开他们的对话框说打开在“GPay”。
