How can I give Page flip effect in UIScrollview?

注意 ：在UIScrollview中，当我们更改Page时，滚动页面向前和向前滚动落后。我们滚动页面的时候可以给页面滚动效果吗？

Note: In UIScrollview when we change Page at that time Scrolling the Page forward & backward. Can it be possible to give Page scroll effect at the time when we scroll page?

推荐答案

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"];

向后翻转 -

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"]; 

您可以在UIScrollView委托时使用此代码。
