推荐答案
根据苹果的文档，加载和音频/视频内容的播放必须从用户的操作触发的：
According to apple's documentation, loading and playback of audio/video content has to be triggered from a user's action:
在Safari浏览器在iOS（适用于所有设备，包括iPad的），其中用户可
是蜂窝网络，并且每个数据单元进行充电，preLOAD和
自动播放被禁用。没有数据加载，直到用户启动它。
这意味着JavaScript的play（）和load（）的方法也是不活跃
直到用户启动播放，除非play（）或load（）方法
由用户操作触发。换句话说，用户启动游戏
按钮的作品，但在onload =播放（）事件不会。
In Safari on iOS (for all devices, including iPad), where the user may be on a cellular network and be charged per data unit, preload and autoplay are disabled. No data is loaded until the user initiates it. This means the JavaScript play() and load() methods are also inactive until the user initiates playback, unless the play() or load() method is triggered by user action. In other words, a user-initiated Play button works, but an onLoad="play()" event does not.
本播放电影：＆LT;输入类型=按钮值=播放
的onClick =document.myMovie.play（）＆GT;
这什么都不做iOS上：＆LT;身体的onLoad =document.myMovie.play（）＆GT;
This does nothing on iOS: <body onLoad="document.myMovie.play()">
