我制作了一个简单的iPhone网络应用程序,我设置了一个启动屏幕和图标以及所有内容。这是它的link。
我遇到的问题是,当我将webapp保存到主屏幕时,白屏(或者我在Safari上打开的页面的屏幕截图)会在启动屏幕之前显示几秒钟。< / p>
我已将其他iPhone网络应用程序(例如JQtouch)添加到我的主屏幕并打开它们,启动屏幕会立即显示出来。
我想知道我的html代码是否有问题???
答案 0 :(得分:2)
尝试将<meta name="viewport" content="width=300px; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" />
更改为<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0;" />
,以便width=device-width
并使用逗号(,
)代替分号(;
),但最后除外这条线。
您的<head>
:
<link rel="apple-touch-startup-image" href="myImage.jpg">
有关具体规格,请参阅iOS Web App Configuration - mobile-meta-links.html:
<!-- startup image for web apps - iPad - landscape (748x1024)
Note: iPad landscape startup image has to be exactly 748x1024 pixels (portrait, with contents rotated).-->
<link rel="apple-touch-startup-image" href="img/ipad-landscape.png" media="screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape)" />
<!-- startup image for web apps - iPad - portrait (768x1004) -->
<link rel="apple-touch-startup-image" href="img/ipad-portrait.png" media="screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait)" />
<!-- startup image for web apps (320x460) -->
<link rel="apple-touch-startup-image" href="img/iphone.png" media="screen and (max-device-width: 320px)" />
另请注意,如果您使用HTML5-doctype,则只会显示启动图像
<!DOCTYPE html>
来自Icons and splash screens for iOS web apps - retina displays also welcome:
要将高分辨率闪屏插入
<head>
,但仅限于此 对于运行iOS5或更高版本的视网膜显示器的iOS设备:function hasRetinaDisplay() { return (window.devicePixelRatio >= 2); } function isAppleDevice() { return (/iphone|ipod|ipad/gi).test(navigator.platform); } function iOSNewerThan(majorVersion) { if(isAppleDevice()) { // Check the version var pattern = /iPhone OS (.*) like Mac/; var result = navigator.userAgent.match(pattern); // Returns "iPhone OS X_Y like Mac, X_Y" var version = result[1].split(''); // Returns X, Y var release = version[0]; return (release >= majorVersion); } return false; } // When we're ready to go... $(document).ready(function() { if(hasRetinaDisplay() && iOSNewerThan(5)) { var highResSplash = '<link rel="apple-touch-startup-image" href="/images/splash-iphone4.png" />'; $('head').append(highResSplash); } });
