How to check if WkWebView finish loading in Objective-C?

Question

I want to load HTML pages using WkWebView and I want to show the page just after it\'s finished loading. As long as it\'s loading I would like to show an activity indicator

For anyone who is experiencing the issue of a webpage containing multiple frames and therefore doing multiple loads which interrups your load animation, I have implemented the following and it works for me in all the situations I have come across so far:

Swift:

var loadCount: Int = 0

override func viewDidLoad() {
    super.viewDidLoad()

    startLoading()
    webview.navigationDelegate = self
    let request = URLRequest(url: url)
    webview.load(request)
}

func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
    loadCount += 1
}

func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {

    loadCount -= 1

    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { [weak self] in
        if self?.loadCount == 0 {
            self?.stopLoading()
        }
    }

}

The basic idea is to start your load animation before you request the url, then count each request being made and only stop the load animation when your request count == 0. This is done after a slight delay as I find that some frames queue up requests synchronously so the next load will begin before the 0.1 second delay has completed.
