What is it ?
This repo is for iOS samples, if I see or learn from somewhere, I will try to implement that as a reminder.
1. Detect human face by using CIDetector
Before starting detection. / After finishing detection.
2. Implement your own Notification Center
In this repo, I am showing how to implement that NotificationCenter by using DesignPattern - Observer https://en.wikipedia.org/wiki/Observer_pattern
