Iphone 如何在“UIScrollview”中提供页面翻转效果？

我正在开发一个应用程序，其中我正在使用

UIScrollview

，因为我需要使用页面翻转效果

如何在

UIScrollview

中实现页面翻转效果

---

注意：在UIScrollview中，当我们更改页面时，向前和向后滚动页面。当我们滚动页面时，是否可以提供页面滚动效果？

向前翻转-

CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.0f];
animation.startProgress = 0;
animation.endProgress   = 1;
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
animation.type = @"pageCurl";
animation.subtype=@"fromRight";
animation.fillMode = kCAFillModeForwards;

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

CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.5f];
animation.startProgress = 0;
animation.endProgress   = 1;
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
animation.type = @"pageUnCurl";
animation.subtype=@"fromRight";
animation.fillMode = kCAFillModeBackwards;

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

向后翻转-

CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.0f];
animation.startProgress = 0;
animation.endProgress   = 1;
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
animation.type = @"pageCurl";
animation.subtype=@"fromRight";
animation.fillMode = kCAFillModeForwards;

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

CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:1.5f];
animation.startProgress = 0;
animation.endProgress   = 1;
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
animation.type = @"pageUnCurl";
animation.subtype=@"fromRight";
animation.fillMode = kCAFillModeBackwards;

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

当UIScrollView委托时，您可以使用此代码。

请更好地解释您的问题。页面翻转效果仅在使用PageViewController时从iOS 5以本机方式提供。在UIScrollView中，当我们更改页面时，向前和向后滚动页面。当我们滚动页面时，是否可以提供页面滚动效果。使用-（void）scrollViewDidScroll:（UIScrollView*）scrollView；方法并以thsi方法执行动画。确保已启用分页。
