Custom view of non-XIB files in IOS development (98)

1 Preface
In the previous section, we talked about the custom view built with the XIB file. Let's take a look at it today without using the custom view of the XIB file.

2. Details
Directory structure

 
 

This time, we will not create XIB files, but directly use the Objective-C file to replace XIB files.
