问题描述
在1.0.1旋转的图标是用CSS旋转的PNG。这种平稳的出现在Android 2.x的我。
In 1.0.1 the spinner icon was a png that was rotated with CSS. This appeared smooth on Android 2.x for me.
在版本1.1-RC1他们已经从巴纽改变图标的.gif动画
In version 1.1-rc1 they have changed the icon from a .png to an animated .gif
在Android上的动画.gif文件奇怪的行为对我来说，对2.2.x的和2.3.x版本不稳定的速度，不要在2.1.x的工作
On Android animated .gifs behave oddly for me, with erratic speeds on 2.2.x and 2.3.x and don't work on 2.1.x
他们为什么要改变它从一个到另一个？它有什么优势不使用CSS转动这似乎是很多更清晰，更流畅的对我巴纽。
Why did they change it from the one to the other? Is there any advantage to not using CSS to rotate the .png which seemed to be a lot crisper and smoother for me.
有谁知道如何实现在1.1-RC1旧装载机？
Does anyone know how to implement the old loader in 1.1-rc1?
推荐答案
JQM可能已经改变了加载图标，因为它依赖于WebKit的动画。 GIF动画具有更多浏览器的支持。
JQM may have changed the loading icon because it relied on webkit animations. The animated gif has support for more browsers.
要实现PNG加载图标覆盖的.ui图标加载类。
To implement the png loading icon override the .ui-icon-loading class.
.ui-icon-loading {
background: url(http://code.jquery.com/mobile/1.1.0-rc.1/images/ajax-loader.png);
background-size: 46px 46px;
width:46px;
height:46px;
-webkit-transform: rotate(360deg);
-webkit-animation-name: spin;
-webkit-animation-duration: 1s;
-webkit-animation-iteration-count: infinite;
-webkit-animation-timing-function: linear;
}
@-webkit-keyframes spin {
from {-webkit-transform: rotate(0deg);}
to {-webkit-transform: rotate(360deg);}
}
