“Movie Format Not Supported” on iPhone with YouTube player in a WebView

由 烂漫一生 提交于 2019-12-23 20:01:02
问题 I'm using a UIWebView on iPhone to play YouTube videos. This is working fine most of the time, but not all. Under some circumstances, apparently related to network connection issues, the error "This movie format is not supported." is shown. This same error can be seen in both Safari and the YouTube player under the same circumstances. Unfortunately it has been seen by Apple during the AppStore testing so they've rejected the app. Can anyone suggest methods for detecting and handling the error

问题 I am currently working on a browser that supports multiple tabs on the iPad. Problem is iOS doesn't allow for more than one tab to be playing audio/video at the same time, trying this causes issues to arise such as all the audio to stop and not come back. I have noticed that Google Chrome's browser actually stops the media in the tab that goes inactive. I am wondering how they go about it. I know it is possible to completely stop the media via a [webView loadRequest:NSURLRequestWithString(@

UIWebView does not show images on iOS9, and SafariViewController does not load HTML files at all?

问题 Just found that UIWebView that load HTML string with images embedded does not work correctly to show the image on iOS9 (GM seed), which worked correctly previously on iOS8 . After viewed the WWDC SafariViewController video here and thought Apple wants us to turn to the new framework, which looks quite promising. But problem is SafariViewController does not support loading local HTML files and it only supports HTTP and HTTPS, so far on iOS9 GM seed and Xcode 7.1 beta. I tried to load it using
