I have an html input type="file" upload form on a page loaded through wkwebview, and I'm trying to allow the ability to upload common document files (pdf, docx, etc). Currently I have the ability to take pictures and browse for images, but documents are greyed out and unavailable. I'm a web developer, and swift is greek to me, so any help would be greatly appreciated!
Here is my view controller
import UIKit
import WebKit
import IJProgressView
import FirebaseMessaging
class ViewController: UIViewController, WKNavigationDelegate {
let webView = WKWebView()
var initialstart = true
override func viewDidLoad() {
webView.backgroundColor = UIColor(red:0.17, green:0.24, blue:0.31, alpha:1.0)
webView.isOpaque = false
webView.allowsBackForwardNavigationGestures = true
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.receivedUrlFromPushNotification(notification:)), name: NSNotification.Name(rawValue: "ReceivedPushNotification"), object: nil)
// Do any additional setup after loading the view, typically from a nib.
guard let url = URL(string: "https://www.website.com/users/account") else { return};
webView.frame = view.bounds;
webView.navigationDelegate = self;
webView.load(URLRequest(url: url));
webView.autoresizingMask = [.flexibleWidth, .flexibleHeight];
view.addSubview(webView)
}
func receivedUrlFromPushNotification (notification: Notification) {
let notification: [AnyHashable : Any] = notification.userInfo!
let url = URL(string: notification["url"] as! String);
webView.load(URLRequest(url: url!))
}
func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
if navigationAction.navigationType == .linkActivated {
if let url = navigationAction.request.url,
let host = url.host, !host.hasPrefix("www.website.com"),
UIApplication.shared.canOpenURL(url) {
if #available(iOS 10.0, *) {
UIApplication.shared.open(url)
} else {
// Fallback on earlier versions
UIApplication.shared.openURL(url)
}
decisionHandler(.cancel)
} else {
decisionHandler(.allow)
}
} else {
decisionHandler(.allow)
}
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
let url = webView.url;
let path = url?.path;
UIApplication.shared.isNetworkActivityIndicatorVisible = false
IJProgressView.shared.hideProgressView()
view.isOpaque = true
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
if (initialstart == true) {
initialstart = false
} else {
UIApplication.shared.isNetworkActivityIndicatorVisible = true
IJProgressView.shared.showProgressView(view)
}
}
}
