CATransition页面顶部卷曲

Question

我想知道是否有人使用CATRANSITION从顶部管理pagecurl。我有以下几种：

CATransition *animation = [CATransition animation]; 
[animation setDelegate:self]; 
[animation setDuration:0.35]; 
[animation setTimingFunction:UIViewAnimationCurveEaseInOut]; 
animation.type = @"pageCurl"; 

animation.subtype = kCATransitionFromTop; 

animation.fillMode = kCAFillModeForwards; 

animation.endProgress = 0.30; 
[animation setRemovedOnCompletion:NO]; 
[self.view.layer addAnimation:animation forKey:@"pageCurlAnimation"]; 

但不幸的是，它总是从底部卷曲页面。如果有人能告诉我如何从顶部卷曲页面，我将非常感激。

非常感谢。

Answer 1

找到答案，需要从右侧设置子类型！

Answer 2

subtype = KCATransitionFromLeft or KCATransitionFromRight 

如果您想要卷页页面的全部动画，您还可以删除animation.endProgress。 =）

Answer 3

我有这个工作。你需要设置animation.type = @“pageUnCurl”; - 谁曾想到！谢谢苹果。

CATransition *animation = [CATransition animation]; 
[animation setDelegate:self]; 
[animation setDuration:0.5]; 
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; 
animation.type = @"pageUnCurl"; 

animation.subtype = kCATransitionFromTop; 
animation.fillMode = kCAFillModeForwards; 
animation.startProgress = 0.3; 
[animation setRemovedOnCompletion:NO]; 

[self.helpView.layer addAnimation:animation forKey:@"pageCurlAnimation"];
