uiwebview

问题 In my application I have a UIWebView that is able to play Youtube videos normally, but I'd like to play some videos from a website other than Youtube. If i try to play those videos in the iPhone Safari browser it opens in the same way that YouTube videos (fullscreen mode, showing the player), but that doesn't happen in the UIWebView inside my application. As an example, consider the following URL: http://m.video.globo.com/#video.php?id=1174097 (don't forget to open it in the simulator) I didn

问题 I would like to Check (boolean value) if PDF content is loaded in the UIWebView. This question already exists, but not this case. It's not as simple as just checking the path extension of the webView Url because this PDF content is generated via ASPX. The extension will return 'aspx'. Also not just looking in the url, the string 'pdf' will always be found in the url since I requesting a PDF file. I need to check if the server really returns a PDF file as it should. Ok, The webView is loaded

问题 I need to cache a web-sourced image (i.e. not bundle sourced) that is going into a webview. Normally I'd just request the image and convert it into base-64 and stick it in the HTML, but if I have 100 images in line I can't quite do that. So I searched around a bit and found a way to grab the image request by subclassing NSURLCache and overriding cachedResponseForRequest . My code is below. I'm able to do the request just fine, I can get the data back and print it out, I made a UIImage from

问题 I am working on a project that displays a PDF in a UIWebView. I have added another UIMenuItem to the UIMenuController in order to do various things with the text in the UIWebView that has been selected. The problem is that I am not able to access the selected text in my newly created selector method. If I use the copy command on selected text first, then I can get that previously copied text from the pasteboard, but a command like [myWebView copy:sender]; called from my new selector does

问题 My app allows users to access a service that plays audio books via the web. I am using a UIWebView to handle this. When the app is exited or the device is put to sleep, the audio stops playing.

However, if you access the same link via the Safari app, the audio keeps playing after the phone is put to sleep. How can I achieve the same effect in my app? 回答1

问题 I work for a media company, and in our iPad application we're upgrading our content so it looks better. Previously, we used a UILabel to display the contents of our posts. I used this to get the actual height of my UILabel: CGSize expectedSize = [label.text sizeWithFont:label.font constrainedToSize:maximumLabelSize lineBreakMode:label.lineBreakMode]; However, we changed our posts' content to HTML, so I'm using a UIWebView. Is there a way to find the true height of the UIWebView, like I do
