Introduction to the
What is a library? A library is a collection of program code, a way of sharing program code. Libraries can be divided into two types depending on the source code
Open source library open source code, you can see the specific implementation such as SDWebImage, AFNetworking
Closed source library is not open source code, is compiled after the binary file, can not see the specific implementation is mainly divided into: static library, dynamic library
Static and dynamic libraries
Static libraries and dynamic libraries exist in the form of static libraries:.a and.framework Dynamic libraries:.dylib and.framework
Let’s start with the production process of library A
1. Project introduction of creating a static library

Let’s start with the production process of library A
1. Create a static library project
Add source code to the static library:
3. Write header files and code methods that need to be exposed:
Public header files need to be dragged into the Public category:
4. Compile on the simulator and real machine respectively, and wait until the. A file changes from red to white show in Finder
5. Merge. A library
A static library file libstaticlibchomp.a will be found in the project file path after the merge
The successfully merged.a library is the final static library that can be used by dragging the header files exposed by the.A library into the project
