UICollectionView insertItem - >调整动画时间？ [英] UICollectionView insertItem -> adjust animation time?

问题描述

所以，我有一个UICollectionView，我插入新项目。

So, I have a UICollectionView where I insert new items.

我使用了 Collection View Programming Guide - 让插入和删除动画更有趣部分

I used the most of the suggestions from the Collection View Programming Guide - section "Making Insertion and Deletion Animations More Interesting"

有没有办法调整动画时间？ （也许我只是在文档中错过了它，但找不到任何关于此的信息）

Is there a way to adjust the animation time? (Maybe I just missed it in the docs, but couldn't find any info on this)

PS：如果我可以编辑也很酷的曲线。你知道Ease-In-Out等等。

PS: If I could edit the curve that would be cool too. You know Ease-In-Out and so forth.

推荐答案

你可以用CALayer改变任何动画速度。所以对于UICollectionView，它看起来如下所示：

You can change any animation speed with CALayer. So for UICollectionView this looks like the following:

[self.collectionView.viewForBaselineLayout.layer setSpeed:0.1f];

你可以改回原来的速度：

And you can change back the original speed:

[self.collectionView.viewForBaselineLayout.layer setSpeed:1.0f];

为此，您可能需要导入QuartzCore：

For this to work you may need to import QuartzCore:

#import <QuartzCore/QuartzCore.h>
