UIView的表面自定义转换/动画（如“水滴效应”） [英] UIView surface custom transformation/animation (like 'a water drop effect')

问题描述

什么是贯彻落实自定义转换（+动画）在查看表面的方式（类似附图片）（的不 在的视图边界的）。

What is the way to implement custom transformation (+ animation) on a view surface (similar to the images attached) (not just the view bounds).

问题主要是在什么是通用方式，以做到这一点（不完全的'水滴效应，但任何例子是pciated肯定AP $ P $）。我想，这就是网格的布局层一些'algorythmic改造，但不知道哪种方式'挖'，在

The question is mainly in what is the general way to do that (not exactly the 'water drop effect', but any examples would be appreciated for sure). I guess, that's some 'algorythmic' transformation of the layer layout 'grid', but not sure which way to 'dig' that in.

（另一种想法是，可能会使用一些框架，但是可以实现，我仍然需要理解的核心逻辑）。

(Another thought is that might be achieved with using some frameworks, however, I would still need to understand the core logic).

感谢您！

要包起来：苹果做到这一点绕了一个名为CAMeshTransform类中的私有API。

To wrap it up: Apple does this with private API around a class called 'CAMeshTransform'.

笔者提出了一个自己编写的替代品：

The author proposes an self-written substitute:
