Question

我是iPad开发人员的新手，

我正在EPUB

上阅读UIWebView内容

我在iPhone上使用UIWebView来显示EPUB内容，但我希望实现类似于图书的翻页动画。

这是Demo Example. 和

这是我的代码段，

提前致谢！

Answer 1

目标iOS5。
使用UIPageViewController。 Here is an example

女士。 Sadun有开源代码，可以构建您的页面here

Here is another person's tutorial

让页面转动动画工作后，内容可以是任何内容，包括HTML页面/链接。

我用Erica的样本来制作一本书。大多数页面都是png，但我使用html页面作为目录。此页面包含指向书中特定页面的链接。内联CSS用于设置页面样式。

请注意，UIPageViewController仅适用于iPad。

以下代码是我实现它的方式。请注意，我的版本一次显示一页，而不是两页。

这是我的页面视图控制器代码：

/*
 About this class:

 - it assumes western left-to-right usage for the page flips
 - it assumes one page in both landscape and portrait
 - it stores but does not use the current page 
 */

#define SAFE_PERFORM_WITH_ARG(THE_OBJECT, THE_SELECTOR, THE_ARG) (([THE_OBJECT respondsToSelector:THE_SELECTOR]) ? [THE_OBJECT performSelector:THE_SELECTOR withObject:THE_ARG] : nil)

Answer 3

由于您使用网络视图来显示您的ePub图书，因此您需要一个网络解决方案。您可以查看http://www.webresourcesdepot.com/5-free-jquery-page-flip-plugins-for-book-like-interfaces/以获取一些示例。

Answer 4

由于您使用的是UIWebView，因此您需要使用JavaScript和/或CSS来完成翻页动画。

你可以去几条路线。

结帐turn.js和jquery mobile page transitions。其中一个解决方案应该适合您。

以下是turn.js的示例代码：

#magazine{
    width:800px;
    height:400px;
}
#magazine .turn-page{
    width:400px;
    height:400px;
    background-color:#ccc;
}
<div id='magazine'>
    <div> Page 1 </div>
    <div> Page 2 </div>
    <div> Page 3 </div>
</div>
$('#magazine').turn();

Answer 5

试试这个：one and two Page Curl Animation
