Question

我想在MBProgressHUD上展示UIWebView。我正在尝试在webview中加载iframe。我的微调器在webview开始加载时显示，但即使它转到webView didFinishLoad()中的断点也不会隐藏。

这是我的代码：

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)
}
}

我注意到webViewDidStartLoad和webViewDidFinishLoad被调用了两次。请帮我。微调器没有隐藏..我使用过Xcode8和Swift 3.

编辑：

我试过了，但它也不起作用：

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)
    }
}

尝试用此替换您的代码：

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)
    }
}

MBProgressHUD没有隐藏 - Swift 3
