Because the black apple system was reinstalled on the previous computer, CocoaPods was reconfigured

What is CocoaPods?

ocoaPods is a tool responsible for managing third-party open source libraries in iOS projects. The source code of the CocoaPods project is managed on GitHub (https://github.com/CocoaPods).

The development of iOS projects inevitably requires the use of third-party open source libraries. When using third-party libraries, in addition to importing source code, integration of these dependent libraries also requires us to manually configure, and when these third-party libraries are updated, we also need It is very troublesome to update the project manually.

The emergence of CocoaPods allows us to save the time of setting up and updating third-party open source libraries. With CocoaPods, we can manage the third-party dependent libraries in a unified manner. Configuration and update only need to be completed with a few simple lines of commands.

Why use CocoaPods?

Before using CocoaPods, when a development project needs to use a third-party open source library, we need to:

Copy the source code of the open source library into the project

Pods

Add some dependent frameworks and dynamic libraries

Set -Objc, -fno-objc-arc and other parameters

Manage their updates

After using CocoaPods, we only need to put the used open source libraries in a file named Podfile, and then execute pod update. CocoaPods will automatically download the source code of these third-party open source libraries and provide it for us Set the corresponding system dependencies and compilation parameters for the project.

The principle of CocoaPods

The principle of CocoaPods is to put all dependent libraries in another project called Pods, and then let the main project depend on the Pods project, thus moving the source code management work from the main project to the Pods project.

Third-party libraries will be compiled into .a static libraries or .framwork dynamic link libraries for our real projects.

CocoaPods will combine all third-party libraries into a project named Pods in the form of targets, which will be placed in the newly generated Pods directory. The entire third-party library project will generate a static library named libPods.a for our project to use.

For resource files, CocoaPods provides a bash script named Pods-resources.sh, which will be executed every time the project is compiled, copying various resource files of third-party libraries to the target directory.

The original project settings have been changed. At this time, if we directly open the original project file to compile, an error will be reported. The Pods project where our project and third-party library are located will be organized and managed in the form of a newly generated workspace, which is convenient for us to intuitively manage the project and third-party library.

CocoaPods uses a file named Pods.xcconfig to set all dependencies and parameters at compile time

CocoaPods installation steps

Ruby environment

1. Set up ruby ​​source

The ruby ​​environment that comes with the Mac system will be installed

1.1, check the ruby ​​source of your computer

ruby -v

Legend has it that the minimum version of ruby ​​supported by CocoaPods is 2.2.2. If your computer version is lower than this version, you can upgrade ruby. The above shows that my computer version does not need to be upgraded. You can ignore the following upgrade operation

sudo gem update --system

1.2 Replace ruby ​​mirror

Catalina

Ruby's default original address is a foreign network address. Use the following command to view the current mirror
gem sources -l

Remove current mirror
gem sources --remove https://rubygems.org/

Add domestic ruby ​​mirror
gem sources -a https://gems.ruby-china.com/

Check the current mirror again and find that it has been replaced successfully

CocoaPods installation

Macos Catalina Install Pod

Before Mac OS X 10.11
sudo gem install cocoapods

After Mac OS X 10.11
sudo gem install -n /usr/local/bin cocoapods

Since the system of this machine is 10.15, choose the latter command input
sudo gem install -n /usr/local/bin cocoapods

2.2, check whether the installation is successful

pod search AFNetworking

I actually looked at this blog configuration at the beginning, but at this step I found that there seems to be a problem

Opened the website https://git.coding.net/CocoaPods/Specs.git
found this look
But the principle is

The Podspec files of all projects are hosted at https://github.com/CocoaPods/Specs. When pod setup is executed for the first time, CocoaPods will update these podspec index files to the local ~/.cocoapods/ directory. This index file is relatively large, about 80M.
And I guess the reason for this is to clone the code of this repository
CocoaPods/Specs
https://github.com/CocoaPods/Specs.git
But the clone code from git is quite full, so it is put on coding, but this warehouse is out of date or private.
So I cloned a warehouse on Code Cloud
