MBProgressHUD not hiding - Swift 3

I am trying to show MBProgressHUD on UIWebView. I am trying to load an iframe in webview. My spinner shows when webview starts loading, but doesn't hide even though it goes to the breakpoint in the webView didFinishLoad().

Here is my code :

class LiveViewController: UIViewController, UIWebViewDelegate {

@IBOutlet weak var liveWebView: UIWebView!

var spinnerActivity: MBProgressHUD! = nil

override func viewDidLoad() {
    super.viewDidLoad()

    liveWebView.delegate = self

    let embededHTML = "<html><body><iframe src=\"\" width=\"100%\" height=\"500\" frameborder=\"0\" scrolling=\"no\"></iframe></body></html>" //link removed
    liveWebView.loadHTMLString(embededHTML, baseURL: nil)
}

public func webViewDidStartLoad(_ webView: UIWebView){
    spinnerActivity = MBProgressHUD.showAdded(to: self.view, animated: true)
    spinnerActivity.label.text = "Loading"
    spinnerActivity.detailsLabel.text = "Please Wait!"
    spinnerActivity.isUserInteractionEnabled = false
}

public func webViewDidFinishLoad(_ webView: UIWebView){
    spinnerActivity.hide(animated: true)
}

public func webView(_ webView: UIWebView, didFailLoadWithError error: Error){
    spinnerActivity.hide(animated: true)
}
}

I noticed that webViewDidStartLoad and webViewDidFinishLoad is being called twice. Please help me. The spinner is just not hiding.. I have used Xcode8 and Swift 3.

Edit :

I tried this but it doesn't work too : 

class LiveViewController: UIViewController, UIWebViewDelegate {

@IBOutlet weak var liveWebView: UIWebView!

var spinnerActivity: MBProgressHUD! = nil

override func viewDidLoad() {
    super.viewDidLoad()

    liveWebView.delegate = self

    let embededHTML = "<html><body><iframe src=\"\" width=\"100%\" height=\"500\" frameborder=\"0\" scrolling=\"no\"></iframe></body></html>" //link removed
    liveWebView.loadHTMLString(embededHTML, baseURL: nil)
}

    public func webViewDidStartLoad(_ webView: UIWebView){
        MBProgressHUD.showAdded(to: self.view, animated: true)

    }

    public func webViewDidFinishLoad(_ webView: UIWebView){
        MBProgressHUD.hide(for: self.view, animated: true)

    }

    public func webView(_ webView: UIWebView, didFailLoadWithError error: Error){
        MBProgressHUD.hide(for: self.view, animated: true)
    }
}

Solution

  • Try to replace your code by this :

    class LiveViewController: UIViewController, UIWebViewDelegate {
    var isHudShow  = false
    @IBOutlet weak var liveWebView: UIWebView!

    var spinnerActivity: MBProgressHUD! = nil

    override func viewDidLoad() {
        super.viewDidLoad()
        liveWebView.delegate = self
        let embededHTML = "<html><body><iframe src=\"\" width=\"100%\" height=\"500\" frameborder=\"0\" scrolling=\"no\"></iframe></body></html>" //link removed
        liveWebView.loadHTMLString(embededHTML, baseURL: nil)
    }

    public func webViewDidStartLoad(_ webView: UIWebView){
     if isHudShow == false
      {
        MBProgressHUD.showAdded(to: self.view, animated: true)
        isHudShow =true
      }

    }

    public func webViewDidFinishLoad(_ webView: UIWebView){
     MBProgressHUD.hide(for: self.view, animated: true)
    }

    public func webView(_ webView: UIWebView, didFailLoadWithError error: Error){
     MBProgressHUD.hide(for: self.view, animated: true)
    }
}
