我一直在http://code.google.com/apis/ajax/playground/?exp=youtube#chromeless_player提供的演示。我想知道的是,如果有一種方法可以讓播放器HTML5或與iOS設備兼容。我似乎無法弄清楚我將如何做到這一點?我認爲這些代碼並不像我用iPhone試過的那樣開箱即用,並且它看起來不起作用......我使用這個的最大原因是因爲我需要能夠調整音量並獲得視頻事件發生變化...如何使用YouTube API來支持HTML5和iOS設備?

從今天(2-28-2012)起,iOS設備上的瀏覽器無法播放視頻。您只能對可以在iOS視頻播放器中播放視頻或在YouTube視頻應用中播放的鏈接進行推測。 Youtube HTML5播放器執行此操作。在不支持Flash的支持HTML5的設備上,它將提供HTML5標記。

3月7日是iOS的一個重大公告,所以也許這會改變。但我不指望它會成爲iOS設備上長期使用的操作方式。

編輯 - 以下是如何做到這一點。

要在iOS上使用此工作,請使用新的HTML5 youtube播放器。 YouTube API博客中的說明和代碼如下: http://apiblog.youtube.com/2010/07/new-way-to-embed-youtube-videos.html

任何想法如何使上述代碼利用iOS應用程序呢?現在只是什麼都沒有顯示出來...應用程序總比沒有好... – dingerkingh 2012-02-29 14:28:05

我有一個像這樣的工作在iOS上的球員的JavaScript API?比如播放,暫停,跳過嵌入播放器中播放的視頻? – wilsonpage 2012-04-09 17:30:23

在IOS上點擊youtube圖標,它會在youtube應用程序中啓動視頻。它不是一個很好的實現,但你可以把它與谷歌和蘋果。不要點擊播放按鈕,因爲這會打破它。問蘋果爲什麼他們的瀏覽器無法播放內嵌視頻... – 2012-04-09 19:04:17
