IOS-Map Project 01-is network programming difficult ???

I was planning to write a blog before. I stopped for a while and didn't write it. I insisted on writing it again. This version started from 01 and added my own originality.

I am still working on iOS map development. I don't know why. I have to ask a big brother, but I don't know what he is talking about, it seems that the problem of data transmission over the network is very difficult... Grandma's, I don't know yet, but the general process seems to be divided into two parts: one is sending and receiving requests, and the other is parsing data, which is generally in JSON format.

Please study it carefully. What kind of experience will be put on it.

 

In the course of learning, I first got a demo, ran it, And then theory. This is a fast way to learn.
