问题 Thanks for viewing my question. Let me describe the app first. I have a tab bar based app for iOS5.1 that is using storyboard and ARC. There are four tabs with a view controller in each one that shows a webview with local HTML files (each view is a different set of html files to display). Currently when a user touches a http or https link, it'll open in Safari. However, I now want it to open within app via a modal view. I currently have the interface created and ready to show, but I can't

问题 I have a simple iOS app with a single view that contains a UIWebView. Within my webView, I display my jQuery Mobile website. Since jQuery Mobile loads pages via ajax, the webViewDidStartLoad and webViewDidFinishLoad methods are NOT called once the initial page loads. I've found similar questions on SO such as this one , but I'm not sure where to use the window.location = "localFunction" call, and no one has yet to confirm this actually works. Here's my issue (example): App Starts

问题 I have an UIWebView to load a html web link:http://m.y.qq.com in my iOS app. I don't know how to detect the playing state of the audio in UIWebView. I just need to know whether the audio in UIWebView is playing or not in my iOS app, so that I can do something.

问题 I'm working on a rich text editor for iOS and have most of it working but running into endless problems ensuring that the cursor is visible in the viewport when the user starts typing. I came up with a novel approach: insert a span at the cursor position, scroll to the span, and then remove it. (I haven't gotten to only scrolling if the span is on-screen.) Here's what I wrote: document.addEventListener('keypress', function(e) { jumpToID(); }, false); function jumpToID() { var id =

问题 I have a UIWebView inside UIScrollView . This idea is to be able to create more reading space on screen when user scroll the webpage upwards - by scrolling the UIScrollView upwards till the toolbar is visible, and obviously when the toolbars is nomore visible actually scroll the webpage to show more content that's on the page. IPhone Safari browser does exactly the same functionality. see screenshot (first) for default behavior i am getting - i guess because : the scrolling message is

问题 Our app has a lot of web views in it and I recently added a NSURLProtocol to interceptor some of the requests from them. I've noticed that some of the web views are calling the +[NSURLPRotocol canInitWithRequest:] method multiple times with what appears to be exactly the same request. Sometimes 6 or 7 times. I'm trying to figure out why this might be occurring. Does anyone have any experience with this? I've logged out the [NSURL absoluteString] and httpMethod values and they are the same for
