uiwebview

As you may know, Android's WebView has a method named addJavascriptInterface() which imports an Android JAVA object to Javascript context. the question is, Is there any equivalent of it on iOS? UIWebView on iOS doesn't have methods to add interface to DOM. But you still can talk to your code from javascript assigning something to window.location and handling that request in webView:shouldStartLoadWithRequest:navigationType: delegate method. I know this question is really old, but it seems that there is a better way to do it now with a WKWebView . See this answer: https://stackoverflow.com/a

I'm trying to display an Activity Indicator View in my app to users while a url is being loaded into a WebView. I've tried toying with activity.startAnimating/activity.stopAnimating and tried placing them in functions, etc. but have not had any luck. The best I have been able to get is the Activity Indicator to appear and animate, but then not stop animating or hide once my url is loaded, so it continues spinning on top of the web page. In other situations, when trying to move around activity.startAnimating, I have encountered the "Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode

I am trying to display a PDF I have stored locally in a UIWebView. This is how I currently attempt to do this: if (![[NSFileManager defaultManager] fileExistsAtPath:self.url]) { LOG_ERROR(@"Couldn't load local file. File at path: %@ doesn't exist", self.url); return; } nsurl=[NSURL fileURLWithPath:self.url]; NSData *data = [NSData dataWithContentsOfFile:self.url]; LOG_DEBUG(@"data length:%d",[data length]); [self.webView loadData:data MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil]; I have also tried passing nil for textEncoding, as well as using UIWebView's loadRequest. The

My app uses UIWebview, and it works well in iOS 5 and iOS 6. However, it doesn't load the webpage in iOS 7 when I build in Xcode 5 and run the same code. - (void)webViewDidFinishLoad:(UIWebView *)webView {} - (void)webViewDidStartLoad:(UIWebView *)webView {} - (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {} All delegate function is not called. But I do set delegate in xib file and code self.theWebView.delegate = self; I didn't find any information via google. Thank you for your help. I moved the loadRequest method to the completion handler of a presentViewController

According to my research: "WebView" can disable "opening links in new windows/tabs". WebView is used by native app developers to display webpages within their app(see Twitter's app). Detecting WebView via user agent doesn't work consistently and isn't a best practice anyway. Simply attempting to open a new window with JS triggers popup blockers; making it an unreliable way to test if a new window can be opened. I need to detect when this feature is not available. Impossible? Additional Explanation I'm trying to detect whether I can open a new window via target=_blank. For example, UIWebView
