如何在UIScrollview中给翻页效果？

注意：在UIScrollView的，当我们在那个时候改变页面滚动页面前进后退&。当我们滚动页面时，是否可以赋予页面滚动效果？

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"]; 

后空翻 -

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的代表使用此代码。
