there are other people's interaction process and some resources, you can go to their own consideration if the implementation of related functions, how to achieve similar effects. Maybe your method is not so perfect, the implementation effect is not as brilliant as the original, but these are all with your thoughts, this is enough. The charm of open source is that, on the basis of their own ideas, but also through the great God's coding habits and implementation methods, oneself from their code
