请问一下，iOS的微信里面，快捷发送最近一张图片（比如刚刚拍摄的一张图片，或者刚刚生成的屏幕截屏），这个功能是如何实现的？是监听了系统的某一个通知吗？
如果有哪位大神知道的，请具体说一下好吗？非常感谢！
I don’t know.
But I also want to know that when entering the page where you can post pictures, read the latest picture and judge the difference between the time and now. If it is less than a certain value (such as 1 minute), it will be displayed.
PhotoKit new framework can achieve this
