前言
最近碰到個需求，需要仿微信語音通話縮小化后，保持界面最上層有一個懸浮的小View可以一點擊就把剛剛縮放掉的界面再放回來，其實本質就是創造了一個新的Window，在這個window上創建了一個rootController并展示他，縮小化時是把controller dismiss掉了，再次點擊那個小View之后把這個controller再展示出來便可以了。同理微信小程序其實也是在一個新的Window中做了一套新的邏輯。隨著現在手機性能的提升，多Window同時存在并不會造成嚴重卡頓，而衍生出來的一種新的開發方式。
實例代碼
上代碼，這個是根據網上找到的類似效果進行了部分修改的，作者叫馮琦帆
