I ran into this as well, and HTML rewriting was the best solution I could come up with. The biggest issue that I ran into with that approach is that the web browser is interactive for up to a couple of seconds until the webViewDidFinishLoad: method is called, so the links seem to be broken … Read more
After experiencing the very same problem and symptoms, I was able to gain access to the Apple Developer Forum thread mentioned here The upshot of the Apple thread is that you must have a valid Intermediate Certificate installed on the server. It is not enough to have only the server certificate installed. I have tested … Read more
The way I got rid of my UIWebView’s memory leakage is by setting its HTML to the empty string. One place to do this is when the view controller containing the web view disappears: – (void) viewWillDisappear:(BOOL)animated { if (self.isMovingFromParentViewController) { [self.wv loadHTMLString: @”” baseURL: nil]; } }
Does UIWebView use the same JavaScript engine as Mobile Safari? UIWebView does not have the Nitro Javascript engine, so it executes JS slower than Mobile Safari. So it’s not the same. Also, does UIWebView support all HTML5 features like Mobile Safari does? I am specifically concerned about Web SQL and Web Workers Not sure about … Read more
After some googling I have finally found a fitting solution for the question I posed. Hopefully this would help those who face the same problem. The trick is with the formatting of the string path when creating an NSURL object for baseURL of a UIWebView. Although usually I use the typical “Users/…../dir/file” in most cases, … Read more
It sounds like the standard caching is not good enough because you have no control over what will be cached and for how long. The easiest way for solving this is by creating your own caching meganism by overriding the NSURLCache. You can find some documentation about that at http://nshipster.com/nsurlcache/ and a sample at http://github.com/evermeer/EVURLCache … Read more
This post has been updated for Swift 5 & WKWebView So this is a really great function you wrote there, OP! Here is just a shorter, more elegant version of your code: // make sure to declare the delegate when creating your webView (add UIWebViewDelegate to class declaration as well) myWebView.delegate = self func webViewDidFinishLoad(webView: … Read more
The implementation by markussvensson has some false alarms, since any UIWindowDidBecomeVisibleNotification is considered as a full screen video playback which is not true. The implementation “AVPlayerItemBecameCurrentNotification” by Selvin can catch movie playback start, but cannot catch movie playback stop. So I combined both implementations and it works as expected. Add observer to both AVPlayerItemBecameCurrentNotification & … Read more
NSString *path; NSBundle *thisBundle = [NSBundle mainBundle]; path = [thisBundle pathForResource:@”first” ofType:@”html”]; NSURL *instructionsURL = [NSURL fileURLWithPath:path]; [webView loadRequest:[NSURLRequest requestWithURL:instructionsURL]]; NSString * jsCallBack = [NSString stringWithFormat:@”myFunction()”]; [webView stringByEvaluatingJavaScriptFromString:jsCallBack]; [webView stringByEvaluatingJavaScriptFromString:@”myFunction()”]; If all this code called from single place, than it won’t work, because page load is asynchronous and page with JavaScript code is not ready … Read more
Here you go: if let pdf = NSBundle.mainBundle().URLForResource(“myPDF”, withExtension: “pdf”, subdirectory: nil, localization: nil) { let req = NSURLRequest(URL: pdf) let webView = UIWebView(frame: CGRectMake(20,20,self.view.frame.size.width-40,self.view.frame.size.height-40)) webView.loadRequest(req) self.view.addSubview(webView) } Edit The alternative is via NSData: if let pdfURL = NSBundle.mainBundle().URLForResource(“myPDF”, withExtension: “pdf”, subdirectory: nil, localization: nil),data = NSData(contentsOfURL: pdfURL), baseURL = pdfURL.URLByDeletingLastPathComponent { let webView = … Read more
