Youtube视频自动播放无法在iphone设备的chrome上运行

Question

if($('.explore-video-btn').length > 0) {
		var video_id = youtube_parser($('.explore-video-btn').attr('data-video-url'));
	}
	
	var tag = document.createElement('script');
	tag.src = "https://www.youtube.com/iframe_api";
	var firstScriptTag = document.getElementsByTagName('script')[0];
	firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
	//Holds a reference to the YouTube player
	
	//this function is called by the API
	if(document.getElementsByClassName('explore-video-btn').length !== 0) {
		document.getElementsByClassName('explore-video-btn')[0].addEventListener('click', function() {
			onYouTubePlayerAPIReady();
		});
	}
	var player;
	function onYouTubePlayerAPIReady() {
	
		setTimeout(function() {
		
			player = new YT.Player('youtube-iframe', {
				videoId: video_id,
				playerVars: {'rel': 0, 'showinfo': 0, 'ecver': 2, 'autoplay': 1},
				events: {
					'onReady': onPlayerReady,
					'onStateChange': onPlayerStateChange
				}
			});
			//subscribe to events
			
		}, 200);
	}
	
	function onPlayerReady(event) {
		event.target.mute();
		event.target.playVideo();
	}
	function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED) {
			event.target.stopVideo();
		}
	}
	

我已经使用youtube API自动播放视频，它在chrome浏览器中的android设备上正常工作，但在chrome浏览器的iphone设备上不自动播放。我发现youtube API文档警告，如"警告：为了防止通过蜂窝网络主动下载，费用由用户承担，嵌入式媒体不能在iOS上的Safari中自动播放-用户总是启动播放。">.

警告称，自动播放在ios中的safari上不起作用，但在ios中没有提到chrome。请帮我找到解决方案。非常感谢。

因为这不是浏览器问题。这是关于iOS的。

在iOS中启动视频的策略。

<video autoplay> elements will now honor the autoplay attribute, for elements which meet the following conditions:
<video> elements will be allowed to autoplay without a user gesture if their source media contains no audio tracks.
<video muted> elements will also be allowed to autoplay without a user gesture.
If a <video> element gains an audio track or becomes un-muted without a user gesture, playback will pause.
<video autoplay> elements will only begin playing when visible on-screen such as when they are scrolled into the viewport, made visible through CSS, and inserted into the DOM.
<video autoplay> elements will pause if they become non-visible, such as by being scrolled out of the viewport.

请在官方网站上查看有关这些限制的完整列表。

不，你不能从IFrame api:

移动注意事项自动播放和脚本播放HTML5元素，仅在某些移动浏览器(如Chrome和Safari)中允许在由用户交互启动的情况下进行回放(例如敲击播放器)。以下是苹果的文档：

"警告：要防止通过蜂窝网络主动下载，请访问由用户承担费用，嵌入式媒体无法在iOS上的Safari——用户总是启动播放。">

由于这种限制，playVideo()、loadVideoById()不能在所有移动环境中工作。

结论->不，你不能
