在xCode中,我同时输入了活动指示器和UIWebView方面,但是在加载网页后,活动指示器将不会隐藏。这是代码,有关如何使它起作用的任何提示?
override func viewDidLoad(){
super.viewDidLoad()
Videoview.delegate = self as? UIWebViewDelegate;
loadAdress()
}
func loadAdress() {
let requestURL = NSURL(string: "https://twitter.com/")
let request = NSURLRequest(url: requestURL! as URL)
Videoview.loadRequest(request as URLRequest)
}
func webViewDidStartLoad(_ : UIWebView) {
ActvityView.startAnimating()
NSLog("The webview is started loading")
}
func webViewDidStopLoad(_ : UIWebView) {
ActvityView.stopAnimating()
ActvityView.isHidden=true;
NSLog("The webview is done loading")
}
func WebViewActvityStopError(_ : UIWebView, didFailLoadWithError error: Error){
ActvityView.stopAnimating()
ActvityView.isHidden=true;
print("Webview fail with error \(error)");
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
谢谢:)

首先,您不应该使用UIWebView
。代替UIWebView
使用WKWebView
要停止UIActivityIndicator
,请使用WKWebView
委托方法
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
DispatchQueue.main.async {
// Hide activity indicator here
}
}
您需要点击以下链接:WKWebView
