uiwebview

问题 tl;dr ? Get the mechanism demonstrated in the link below to behave with GPU acceleration on Android Chrome & default browser. UPDATE 2 (2014-01-13 13:25:30Z): According to bref.it's comment below, the reported behaviour is fixed as of Android 4.4 KitKat — but the fix I described below now breaks it! Sod's law. UPDATE 1 (2012-11-01 17:54:09Z): The buggy behaviour is inferrable from the transformation matrix as reported by the computed style of the transformed element, which returns a pixel

问题 I need to use a website with quite a bit of content in my App via UIWebView . When I scroll the page in Mobile Safari everything scrolls smoothly. Even if I scroll fast - the grey squared background appears but is rendered properly after a few moments (less then 0.5 seconds). The same page in UIWebView scrolls jerkily if scrolled fast and doesn't show the grey squared background. I guess Mobile Safari shows the grey squared background first and renders after that while UIWebview stops the

问题 Yesterday we tried the developer previews iOS 8 beta 5 with Xcode 6 Beta 5 for our App. We use location services in the webview components of our hybrid app. I recognized that geolocating via UIWebView ist not working anymore. I verified this behavior with an example from scratch loading example for geolocation from the w3schools.com into a UIWebView. With iOS 7, (Base SDK 7.1, built with XCode 5), the notification for acceptance of the location service is prompted an after that, the app

问题 I've been developing an iPad application that uses UIWebView to display some text and image data which is working great. However, I'm trying to stop the user selection that occurs when the user hold the screen for a couple of seconds. The usual methods seem to work fine on everything other than iOS 4.3. I've tried a couple of different things such as: body, html { -webkit-user-select:none; -webkit-tap-highlight-color: rgba(0,0,0,0); -webkit-touch-callout:none; } * { -webkit-user-select:none;

问题 I'm trying to view a facebook-comments plugin in a UIWebView on an iPhone application. I began with Facebook's iOS tutorial, where I implemented Single Sign-On. The app delegate takes care of Facebook's Single Sign-on, then redirects me to my single view controller, which displays a title bar and a UIWebView. I load the webview with a local file called "comments.html" which has been added and copied to my bundle/project directory. NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]

问题 In my app I need to send an array from Objective C to javascript. I read on the web that I can use this instruction: stringByEvaluatingJavaScriptFromString , also i made so: Objective C snippet NSMutableArray *names = [[NSMutableArray alloc]init]; NSMutableArray *srcs = [[NSMutableArray alloc]init]; for (int i = 0; i < [site count]; i++) { NSDictionary *dictData = [site objectAtIndex:i]; [names addObject:[dictData objectForKey:@"name"]]; [srcs addObject:[dictData objectForKey:@"src"]]; } //

问题 I've found some similar posts, but they don't seem to have any effect with what I'm doing. I've got a UIWebView that I'm using to display local content in my bundle. Specifically I'm displaying a docx file. The user should rarely ever look at this document, and my app is tight on memory, so what I want to do is prevent the UIWebView from caching the document. Another viable option is to clear the cache when the user leaves the view. I'm totally ok with having to load it from scratch every

问题 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

问题 i want to store the current scroll position of a webView and when i launch the application again . i want to restore that scroll position again .. How to do that ??? 回答1: UIWebView is not a subclass of UIScrollView so you can't do it the "normal" way. Looks like this javascript solution will do what you need: http://shortdivision.wordpress.com/2008/10/14/going-back-to-the-last-place-you-were-in-a-uiwebview/ 回答2: Since iOS5 UIWebView has scrollView property. You can use variable of type
