uiwebview

问题 I have an app that contains a UIWebView. I would like the user to be able to view webpages they've previously navigated to when off line. How should I go about making this work? Thanks! 回答1: You're going to have to download and cache all the content for each page manually, then recreate them as local pages.

问题 This has been the most frustrating thing I've ever had the misfortune of doing, ever. I have a UIWebView. It goes to http://m.youtube.com.

If you click the "Done" button while a video is playing, the video stops, but the video element shows a double preview image: One in the background, which is rotated 90º and one in the foreground that is the correct orientation.
