YouTube API无法在iOS(iPhone/iPad)中运行,但在桌面浏览器中运行良好？

Question

我在简单的单页网站中使用YouTube API.我能够播放视频,我的所有YouTube功能都可以在桌面浏览器中成功运行(IE 7除外 - 也许这个问题会在你帮我回答这个问题时得到解决)但它似乎不起作用完全适用于iOS(iPhone和iPad).YouTube播放器根本无法显示,并且在iOS中根本没有关于YouTube功能的回忆.

下面是我的代码实现.如果我提供的任何问题信息对这个问题有帮助,请告诉我.我想在解决此问题时尽可能简单地开始,然后在必要时引入其他信息.

根据其他SO帖子,iOS上存在限制,其中"...嵌入式媒体无法在iOS上的Safari中以编程方式自动播放 - 用户始终启动播放."

我遇到了同样的问题,结果发现你可以正确嵌入一个YouTube-API IFrame并在iOS上显示YouTube的大红色"播放"按钮,这只是iOS不会让你用你自己的控件启动/停止视频和JavaScript.例如,你可以下一个/上使用JavaScript,但不能播放/暂停,这必须通过单击来完成对视频,然后用本机控制视频进度条旁边.

但是关于你的第一段的最后一句并且放弃这些限制,YouTube播放器应该表明,你所做的事情有些不对劲(虽然我不够专业,无法说出什么).我也是在一个简单的单页网站上做的,随便看看我做了什么.

希望有所帮助!
