7.git push origin
The complete file directory is as shown below: 
5. After success, the code will be uploaded to your github warehouse, you can open it Check the warehouse. Next, you need to tag the project and synchronize it to the remote warehouse:
git tag 1.0.0
git push origin --tags
6. Now that the ithub-related operations are complete, we need to start preparing for uploading cocoapods. First, create a podspec file and execute it in the project root directory:
pod spec create hzqCocoaPodsTest
My folder name here is hzqCocoaPodsTest, so change it according to your actual situation. After the creation is completed, make changes to the podspec and open the podspec file with sublime text. The content that needs to be modified is as follows: 7. 
Then you need to register a trunk account (if this is not the first time, enter: pod trunk add -owner ARAnalytics email):
pod trunk register 邮箱 昵称 --description="描述"
After success, there will be a prompt to open your mailbox for verification, open your mailbox and click the link to verify (it may be in the trash). After verification, enter:
pod trunk me
Verify to see if activation is successful. Then check locally whether the spec file is qualified:
pod spec lint hzqCocoaPodsTest.podspec
If an error is reported, modify it according to the prompts. If it is a warning, you can execute:
pod trunk push --allow-warnings
This step may take a long time and may cause network errors:
[!] There was an error pushing a new version to trunk: Net::OpenTimeout
Just re-execute the command.
If:
[!] Unable to accept duplicate entry for: test (0.0.1) appears
, it means that the submission to the cocoapods warehouse has been successful, then it is possible that the local warehouse has not been updated. Update local repository:
pod repo update --verbose
Displaying this information means that you have uploaded successfully. You can execute:
pod search TestCocoapods
Make an inquiry.
After the above operation is successful, you can use cocoapods to use the library you uploaded.
