  1. YES. Create a webview then load this html page.
  2. YES. (same as answer 1)

  3. YES .

    • To send to html page: call [webView stringByEvaluatingJavaScriptFromString:function];
    • To send to swift/objective-c : handle shouldStartLoadWithRequest of your UIwebview.

    -(BOOL) webView : (UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *) request navigationType : (UIWebViewNavigationType)navigationType {

    if ([[[request URL] absoluteString] hasPrefix:@"yourPrefixe:"]) {
    //do your works
    //then cancel current request
    return NO;
}
return YES;

    }

  • html text can be embedded into labels as NSAttributedString instances
  • HTML content that has scripts and stuff can be put into a web view container: UIWebView or WKWebView
