sproutvideo播放按钮在Apple设备上不起作用

Question

我使用sproutvideo存储视频，我尝试使用jQuery UI设置控制栏，但播放按钮不适用于iPhone和iPad等Apple设备。 这是有效的link。 那是我的代码。

var videoPlayer;
$(document).ready(function(){
	$('.progress').slider({
		value: 0,
		orientation: "horizontal",
		range: "min",
		animate: true,
		slide: function(event, ui) {
			videoPlayer.seek(ui.value);
		}
	});
	
	var _duration = 0, _playing = false, _volume = 1, _fullscreen = false;

	var videoPlayer = new SV.Player({videoId: 'e898d2b5111be3c860'});
	
	videoPlayer.bind('ready', function(event){
		_duration = event.data.duration;
		$(".progress").slider("option", "max", _duration);
	});

	videoPlayer.bind('progress', function(event){
		$('.progress').slider("option", "value", (event.data.time));
	});

	videoPlayer.bind('pause', function(event){
		_playing = false;
		$('.play-pause i').removeClass('icon-pause').addClass('icon-play');
	});

	videoPlayer.bind('play', function(event){
		_playing = true;
		$('.play-pause i').removeClass('icon-play').addClass('icon-pause');
	});

	videoPlayer.bind('volume', function(event){
		_volume = event.data;
		if (_volume == 1) {
			$('.volume i').removeClass('icon-volume-off').addClass('icon-volume-up');
		} else if (_volume == 0) {
			$('.volume i').removeClass('icon-volume-up').addClass('icon-volume-off');
		}
	});

	$('.play-pause a').click(function(){
		if (!_playing) {
			videoPlayer.play();
		} else {
			videoPlayer.pause();
		}
	});

	$('.volume a').click(function(){
		if (_volume == 0) {
			_volume = 1;
		} else {
			_volume = 0;
		}
		videoPlayer.setVolume(_volume);

	});

	$('.fullscreen a').click(function(){
		var elem = $('.player')[0];
		if (!_fullscreen) {
			if (elem.requestFullscreen) {
				elem.requestFullscreen();
			} else if (elem.mozRequestFullScreen) {
				elem.mozRequestFullScreen();
			} else if (elem.webkitRequestFullscreen) {
				elem.webkitRequestFullscreen();
			}
			_fullscreen = true;
		} else {
			if (document.exitFullscreen) {
				document.exitFullscreen();
			} else if (document.mozCancelFullScreen) {
				document.mozCancelFullScreen();
			} else if (document.webkitCancelFullScreen) {
				document.webkitCancelFullScreen();
			}
			_fullscreen = false;
		}
	});

});

Answer 1

移动版Safari不允许调用play()上的<video>方法，除非它由MouseEvent触发。由于SproutVideo播放器API使用Window.postMessage()与播放器iframe进行通信，MouseEvent将丢失，Safari将不允许调用play()函数。对于YouTube javascript API，Vimeo javascript API以及与使用iframe的基于iframe的视频播放器进行通信的任何API，这也是一个问题。

不幸的是，目前还没有解决方法。一个好的临时解决方案是有条件地隐藏iOS设备上的自定义播放器控件，而是使用原生视频播放器。
