Okay, so the app was built with SwiftUI and embeds pages from our website.
But, to tap on contact numbers, emails and other links and such, the user has to press the buttons for long to open up.
Is there a better way to go about this, with all humility?
And it seems the webview also does not update any changes from the website unless I uninstall and reinstall it. I dont know if it is because I have not published the app yet. Any ideas, please?
The code for the webkitview is below, please:
import SwiftUI
import WebKit
import SwiftData
struct HomeView: View {
var body: some View {
ScrollView {
ZStack {
Webview(url: URL(string: "https://www.******.com/appmain")!)
.frame(height: 1400)
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
HomeView()
}
}
struct Webview: UIViewControllerRepresentable {
let url: URL
func makeUIViewController(context: Context) -> WebviewController {
let webviewController = WebviewController()
let request = URLRequest(url: self.url, cachePolicy: .returnCacheDataElseLoad)
webviewController.webview.load(request)
return webviewController
}
func updateUIViewController(_ webviewController: WebviewController, context: Context) {
//
}
}
class WebviewController: UIViewController, WKNavigationDelegate {
lazy var webview: WKWebView = WKWebView()
lazy var progressbar: UIProgressView = UIProgressView()
deinit {
self.webview.removeObserver(self, forKeyPath: "estimatedProgress")
self.webview.scrollView.removeObserver(self, forKeyPath: "contentOffset")
}
override func viewDidLoad() {
super.viewDidLoad()
self.webview.navigationDelegate = self
self.view.addSubview(self.webview)
self.webview.frame = self.view.frame
self.webview.translatesAutoresizingMaskIntoConstraints = false
self.view.addConstraints([
self.webview.topAnchor.constraint(equalTo: self.view.topAnchor),
self.webview.bottomAnchor.constraint(equalTo: self.view.bottomAnchor),
self.webview.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
self.webview.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
])
self.webview.addSubview(self.progressbar)
self.setProgressBarPosition()
webview.scrollView.addObserver(self, forKeyPath: "contentOffset", options: .new, context: nil)
self.progressbar.progress = 0.1
webview.addObserver(self, forKeyPath: "estimatedProgress", options: .new, context: nil)
}
func setProgressBarPosition() {
self.progressbar.translatesAutoresizingMaskIntoConstraints = false
self.webview.removeConstraints(self.webview.constraints)
self.webview.addConstraints([
self.progressbar.topAnchor.constraint(equalTo: self.webview.topAnchor, constant: self.webview.scrollView.contentOffset.y * -1),
self.progressbar.leadingAnchor.constraint(equalTo: self.webview.leadingAnchor),
self.progressbar.trailingAnchor.constraint(equalTo: self.webview.trailingAnchor),
])
}
// MARK: - Web view progress
override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
switch keyPath {
case "estimatedProgress":
if self.webview.estimatedProgress >= 1.0 {
UIView.animate(withDuration: 0.3, animations: { () in
self.progressbar.alpha = 0.0
}, completion: { finished in
self.progressbar.setProgress(0.0, animated: false)
})
} else {
self.progressbar.isHidden = false
self.progressbar.alpha = 1.0
progressbar.setProgress(Float(self.webview.estimatedProgress), animated: true)
}
case "contentOffset":
self.setProgressBarPosition()
default:
super.observeValue(forKeyPath: keyPath, of: object, change: change, context: context)
}
}
}
Thanks so much in advance.
