Iphone JavaScriptYouTubeAPI:永久缓冲-UIWebView iOS
我正在UIWebView中使用YouTube API 我已经用我在UIWebView中加载的HTML5播放器创建了一个NSString。在iphone5和iPad上,一切都能完美运行 但是,如果我使用iPhone4测试应用程序,播放器会一直返回缓冲状态。只有当我明确按下播放按钮时,播放器才会开始播放,而不会再次停止进行缓冲。看起来,虽然视频已经被缓冲,播放器仍然给我这个状态 有人知道这个问题吗?有什么想法吗Iphone JavaScriptYouTubeAPI:永久缓冲-UIWebView iOS,iphone,ios,uiwebview,youtube,youtube-api,Iphone,Ios,Uiwebview,Youtube,Youtube Api,我正在UIWebView中使用YouTube API 我已经用我在UIWebView中加载的HTML5播放器创建了一个NSString。在iphone5和iPad上,一切都能完美运行 但是,如果我使用iPhone4测试应用程序,播放器会一直返回缓冲状态。只有当我明确按下播放按钮时,播放器才会开始播放,而不会再次停止进行缓冲。看起来,虽然视频已经被缓冲,播放器仍然给我这个状态 有人知道这个问题吗?有什么想法吗 提前非常感谢 在LBYouTubePlayerViewController.m文件中 在
提前非常感谢 在LBYouTubePlayerViewController.m文件中 在旧方法上替换以下方法 然后测试

我不使用LBYouTubePlayerView。应用程序中使用UIWebView。无论如何,感谢您的回复!我也面临同样的问题,兄弟,但是,我用了LBYoutubPlayer。。。检查一下,我希望你能解决你的问题。。
