uiwebview

问题 Inside UIWebView, I want to get the html data of the image when the user clicks the image on the web. When I say html data, I mean data as below: <img data-sz="f" name="QC6TSb_zoErN3M:" class="rg_i" alt="blahblah" jsaction="load:str.tbn" src="data:image/jpeg;base64,/9j/blahblah//9k=" style="width: 289px; height: 152px; margin-left: 0px; margin-right: 0px; margin-top: 0px;"> just like the way you can do with developer tool inspector on your PC web browser (In fact, all I need is inside the src

问题 I have a detail view where I want to show a title, subtitle and content for articles. I want to be able to use HTML to format the text, so I've used a UIWebView for showing the article body. This works perfectly. How ever, all of this, is inside a UIScrollView, so my issue is that I have to calculate the height of the UIScrollView? This is how it works today: And this is how it looks like in Storyboard: So what I need to find out, is what is the correct code and syntax to calculate the

问题 I would like to diplay HTML in iPhone UIWebView. My HTML looks like text text <img src.../> text text How can I cause the component (via JavaScript or Objective C) to fit the image size to a window - i.e text size will remain the same but image will be reduced/enlarged proportionally to prevent horizontal scrolling ? Thanks 回答1: You have to know what the HTML looks like, because the only way to do that is to manipulate the DOM. On the Mac you could access the DOM via Objective C, but that API

问题 How I can detect when the magnifying glass comes up in a UIWebView? 回答1: Assuming you're writing an app to release on the app store, you can't - the structure of a UIWebView is opaque to you, and you can't drill down into its component parts. Whilst I suspect it would be possible to descend into its structure and figure out exactly what was getting triggered when, you run a very large risk that Apple will change UIWebView's structure in a subsequent OS update and break your app. So unless you

问题 How do I detect whether a web page in a UIWebView needs to use HTTP or HTTPS? I have an address bar where the user can type in "www.apple.com" and then I convert this to a NSString with http:// in front of it. If Apple.com requires HTTPS though, how would this be handled? What exactly should I do? Thanks for your help! 回答1: In most cases, a web site that requires HTTPS is set up to automatically redirect to the correct SSL port. In generally goes like this: Enter the URL http://www.mysite.com

问题 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 回答1: 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.:

问题 I am using a UIWebView to show a email subscription sign up page. It is not a https:// page so I obviously need to make an exception. I don't want to set it to NSAllowsArbitraryLoads because it is only one page in the whole app and the app may get rejected. So I have used the code below in my info.plist file but I still get the error. Lots of stackoverflow answers point towards this code however I can't get it to work in xcode 8/ ios 10. App Transport Security has blocked a cleartext HTTP

问题 I am developing an app for iPad which contains one or more youtube videos embedded in a UIWebView. I am using the Youtube iframe API. The video shows up fine and the user can use the normal controls fine. However, I want to pause the video when an external event happens. I am attempting to do this by using stringByEvaluatingJavascripFromString with "player.pauseVideo()". However, on inspection it appears that player.pauseVideo is undefined. Strangely this only appears to be a problem in the
