1 创建主屏幕图标（Creating a home screen icon ，for ios）

//57*57<link rel="apple-touch-icon" href="/custom_icon.png"/><link rel="apple-touch-icon" href="touch-icon-iphone.png" /><link rel="apple-touch-icon" sizes="72x72" href="touch-icon-ipad.png" /><link rel="apple-touch-icon" sizes="114x114" href="touch-icon-iphone4.png" /><link rel="apple-touch-icon" sizes="144x144" href="touch-icon-ipad-retina.png" />

2 启动画面图像（Creating a splash screen， for ios）

3 全屏（Making it full-screen， for ios）– 更像本地App

<meta name="apple-mobile-web-app-capable" content="yes" />

developer.apple.com/library/IOs/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html#//apple_ref/doc/uid/TP40002051-CH3-SW2

4 改变状态栏（Changing the phone status bar, for ios）

content属性default, black and black-translucent

<meta name="apple-mobile-web-app-status-bar-style" content="black" />

*developer.apple.com/library/IOs/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html#//apple_ref/doc/uid/TP40002051-CH3-SW1

5 阻止缩放（Preventing scaling）

<meta name="viewport" content="user-scalable=no, width=device-width" />

6 阻止弹性滚动（Preventing elastic scrolling）

<script>function BlockMove(event) { //Tell Safari not to move the window. event.preventDefault() ;}</script><body ontouchmove="BlockMove(event);" > ...</body>

7 检测屏幕是否旋转（Detect whether device supports orientationchange event, otherwise fall back to the resize event）

//Detect whether device supports orientationchange event, otherwise fall back to//the resize event.var supportsOrientationChange = "onorientationchange" in window, orientationEvent = supportsOrientationChange ? "orientationchange" : "resize";window.addEventListener(orientationEvent, function() { alert('HOLY ROTATING SCREENS BATMAN:' + window.orientation + " " + screen.width);}, false);

8 禁止webapp跳转到safari（for ios）

// Mobile Safari in standalone modeif (("standalone" in window.navigator) && window.navigator.standalone) { // If you want to prevent remote links in standalone web apps opening Mobile Safari, change 'remotes' to true var noddy, remotes = false; document.addEventListener('click', function(event) { noddy = event.target; //Bubble up until we hit link or top HTML element. Warning: BODY element is not compulsory so better to stop on HTML while (noddy.nodeName !== "A" && noddy.nodeName !== "HTML") { noddy = noddy.parentNode; } if ('href' in noddy && noddy.href.indexOf('http') !== -1 && (noddy.href.indexOf(document.location.host) !== -1 || remotes)) { event.preventDefault(); document.location.href = noddy.href; } }, false);}

9 禁用手机号码链接（for ios）

<meta name="format-detection" content="telephone=no" />

10 阻止旋转屏幕时自动调整字体大小

-webkit-text-size-adjust:none;

11 IOS中禁止用户选中文字

-webkit-user-select:none;

12 iOS中如何禁止用户保存图片复制图片

-webkit-touch-calloutt:none;

13 语音输入

14 文件上传, 从相机捕获媒体

<input type="file" accept = "image/*; capture=camera" /><input type="file" accept = "video/*; capture=camcorder" /><input type="file" accept = "audio/*; capture=microphone" />
