Having some issues with a webview that turns blank when app is in background for a while. I want the webview to reload if it has been terminated when the app returns to foreground.
The structure of the webview is basically like this:
import SwiftUI
import WebKit
struct WebView: UIViewRepresentable {
func makeUIView(context: Context) -> WKWebView {
let webView = WKWebView()
return webView
}
func updateUIView(_ webView: WKWebView, context: Context) {
let html = "<html><body>Hello World!</body></html>"
let baseUrlWk = Bundle.main.bundleURL
webView.loadHTMLString(html, baseURL: baseUrlWk)
}
}
I've tried to implement a reload with WebContentProcessDidTerminate - and it actually solved the problem but also has some unwanted side effects. The webview reload seems to trigger on many things - e.g. when a sheet is presented without any State-variable being changed. Very disturbing...
import SwiftUI
import WebKit
class WebViewNavigationDelegate: NSObject, WKNavigationDelegate {
func webViewWebContentProcessDidTerminate(_ webView: WKWebView) {
webView.reload()
}
}
struct WebView: UIViewRepresentable {
private let navigationDelegate = WebViewNavigationDelegate()
func makeUIView(context: Context) -> WKWebView {
let webView = WKWebView()
webView.navigationDelegate = navigationDelegate
return webView
}
func updateUIView(_ webView: WKWebView, context: Context) {
let html = "<html><body>Hello World!</body></html>"
let baseUrlWk = Bundle.main.bundleURL
webView.loadHTMLString(html, baseURL: baseUrlWk)
}
}
How can I implement the webViewNavigationDelegate without having the unwanted side effects?
