如何在 webView 中赋予页面卷曲动画?

问题描述

我正在开发 PDF 阅读器应用程序.如果我显示 pdf 文件，那么我无法更改它的字体大小.

I am working on PDF Reader application. if i display pdf file then i am not able to change font size of this.

所以我在 UIWebView 中显示 ePub 文件.但我的问题是如何像 iBook 和 kindle 应用程序那样在 UIWebView 中添加页面卷曲动画.

So i display ePub file in UIWebView. But my problem is how to add page curl animation in UIWebView like iBook and kindle apps does.

推荐答案

我已经创建了一个名为 myWebView 的 UIWebView，点击按钮后会在 webview 上显示 curl 效果:-

I have created a UIWebView named myWebView and on clicking the button the curl effect will be shown on the webview:-

    -(IBAction) nextPageAnimationForWebView{        
    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];
    [animation setDuration:1.0f];
    animation.startProgress = 0.5;
    animation.endProgress   = 1;
    [animation setTimingFunction:UIViewAnimationCurveEaseInOut];
    [animation setType:@"pageCurl"];

        //[animation setType:kcat]; 
        [animation setSubtype:kCATransitionMoveIn];

    [animation setRemovedOnCompletion:NO];
    [animation setFillMode: @"extended"];
    [animation setRemovedOnCompletion: NO];
    [[myWebView layer] addAnimation:animation forKey:@"WebPageCurl"]; 

}
