Swift仿微信语音通话最小化时后的效果实例代码

时间：2021-12-23 15:18     来源/作者：醉梦弦音

前言

最近碰到个需求，需要仿微信语音通话缩小化后，保持界面最上层有一个悬浮的小View可以一点击就把刚刚缩放掉的界面再放回来，其实本质就是创造了一个新的Window，在这个window上创建了一个rootController并展示他，缩小化时是把controller dismiss掉了，再次点击那个小View之后把这个controller再展示出来便可以了。同理微信小程序其实也是在一个新的Window中做了一套新的逻辑。随着现在手机性能的提升，多Window同时存在并不会造成严重卡顿，而衍生出来的一种新的开发方式。

实例代码

上代码，这个是根据网上找到的类似效果进行了部分修改的，作者叫冯琦帆
