Improving UIWebView initialization time

由 独自空忆成欢 提交于 2019-12-07 17:52:01
问题 My company uses a UIWebView to display ads. The issue I'm having is that initializing a UIWebView appears to be expensive; profiling with Time Profiler shows [UIWebView alloc] initWithFrame:CGRectMake(0,0,500,500)] to take 31–40ms. This is enough to cause noticeable frame drops in games running at 60 FPS. Is there a way to workaround this slow initialization time? My current ideas are to create a UIWebView when the app launches (but before gameplay has started), and reuse that (potentially

由 强颜欢笑 提交于 2019-12-07 17:33:35
问题 I am trying to display my facebook page wall (a link of the form http://www.facebook.com/PAGE_NAME?sk=wall) by passing this as a request to UIWebView. The view opens with the generic page (http://www.facebook.com/PAGE_NAME) unless I login to facebook inside my app UIWebView. The same link works fine in Safari even if I am not logged in. How can I make the UIWebView show the wall page? 回答1: Facebook redirects Facebook pages differently on the mobile device over the computer web browser. You'll

Why UIWebView Eating so many Memory?

由 社会主义新天地 提交于 2019-12-07 16:50:02
问题 I'm using a UIWebView to load a pure Text HTML page for my iPad app. The size of the HTMP page is only 40KB. But when I use the instrument to monitor the memory use for loading the UIWebView, I found down it consumes like 20MB memory, if I scroll the web view, the memory is even getting higher. Finally I get a level 1 memory warning. Could anyone help me with this? How could I reduce the memory for this? (I need to use the HTML to show the text here). NSString *htmlPath = [[NSBundle

Stop the auto resize of the uiwebview web content when focus on input field

由 旧巷老猫 提交于 2019-12-07 15:28:52
问题 I have a UIWebView with a html form in it. The problem is that when I tap on the input field, the UIWebView automatically zoom in to the area close to the input field with the keyboard shows up.

(it is already registered with the keyboard hide event) Thanks. 回答1: Either set the font-size CSS

UIWebview load different files switch langage

由 不想你离开。 提交于 2019-12-07 15:17:35
I have differents embedded HTML files in different languages. I'd like to load the correct files in a webview based on the current langage. Is there a way to do that as easily as NSLocalizableString? thanks If you use "localized resources", for example english version of "index.html" in "en.lproj/index.html", french version of "index.html" in "fr.lproj/index.html", then many resource functions will automatically select the correct version (based on the user's language setting), e.g.: NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"]; To create a localized

UIWebView Local Video / Audio playback in iOS not working, using Meteor (PhoneGap)

由 坚强是说给别人听的谎言 提交于 2019-12-07 14:14:14
问题 I'm using Meteor for building a really simple app (in theory). Basically a play button that should start a video. This sounds easy, but there seems to be something fundamentally wrong with how <video> and <audio> tags are handled in iOS UIWebView. It is my understanding that Meteor utilizes a local server so you can load asset files from the /public -folder in your Meteor application. This works as expected for images: <img src="/images/image.png"> However, doing the same with videos and

How do I catch UIWebView errors in MonoTouch?

Here's an answer for a similar question in Objective C but I'm not sure what's the right way to translate it to MonoTouch. Basically, I want to be able to catch JavaScript errors and know at least filename and line number—unfortunately, window.onerror doesn't give this crucial information. In particular, I'm not sure if I should expose a native library or if I can write this in pure MonoTouch. Dan Abramov I adopted Pablo's UIWebView+Debug category inspired by Robert Sanders and Kresimir Prcela's answers . Note that his code also includes a private API call you can use to enable remote web

On Mac Safari and Chrome, this dark select box appears correctly: In iOS Safari, it gets cut off at the border of the selected div: What could make that happen?
