② Cocoapods principle and podspec file uploading operation

cocoapods principle

Gem It's a management Ruby Standard packages for libraries and programs , It passes through Ruby Gem（ Such as http://rubygems.org/ ） Source 、 install 、 Upgrade and uninstall packages , It's very convenient .

Can pass pod --versionn see pod Version number
Can pass ruby -v see ruby Version number
Can pass gem -v see gem Version number

pod Basic operation

1. View the third-party framework repository source pod repo
2. Remove warehouse source pod repo remove master
3. Add warehouse source pod repo add master http://git.oschina.net/akuandev/Specs.git
4. initialization ( Download all the third-party framework information in the server , Cache to local computer ) pod setup
5. pod search Framework keywords — Cached from local " Third party framework description information " Retrieved... From the generated retrieval file Information about the relevant framework
6. Delete cocoapods Index file rm ~/Library/Caches/CocoaPods/search_index.json
7. establish Podfile file , Go into your own project ( First level directory )
   • Podfile The function of documents ?
     answer : It's really just using ruby Grammatically written “ The framework depends on the description file ”; Just tell cocoapods Which frameworks need to be downloaded and integrated
   • Create command pod init
8. Install the frame pod install

Remote index library

`pod setup``
In fact, it is to download the remote index library to the local index library

If we pod install after , Then download the three parties to the project .
When we use these source codes again in another project , then install after , It will be soon , Because a local backup has been made

When we first pod search It's going to be slow , Because it will be downloaded again , Then put it in the cache , So it will be much faster to perform this operation next time . The following figure shows the cache path

Create a remote library , And make PodSpec adopt trunk push podspec file

• First step , Upload items to github, And label it

  • See my first componentization article for specific operations git Basic use
  • git push origin master
  • git tag '1.0.0'
  • git push --tags

• The second step , register trunk

  • pod trunk register 157******[email protected] 'wanggang' --verbose
    –verbose Parameter is used to output debugging information during registration
  • After registration, the email will be sent to you , Go in and check .

• The third step , Configure and upload the framework PodSpec file

  • principle

    • PodSpec file Describe your framework information ： author , edition , Download address, etc
    • pod search Search framework , It is based on the information in this
    • Be careful : Generally, the name of this file is consistent with the project name
    • Create command ：pod spec create File name
    • I'll do it myself ：
      $ cd /Users/liuxitong/Desktop/testLib
      $ pod spec create testLib
      This creates , As shown in the figure ：
      

  • PodSpec File format

    • Can be downloaded by cocoapods Description information in the management framework , You can also check on the official website The website links
    • pod spec lint podspec file
    • If the check fails , If you find any problems, you can modify them podspec Corresponding place .
    • some podspec Field interpretation in ：
      spec.source_files： Which tag files to get from the address Wildcards denote directories , namely classes Directory in folder
      spec.source_files = “Classes”, "Classes//*.{h,m}"

  • adopt trunk push podspec file

    • pod trunk push
    • I'll do it here pod trunk push testLib.podspec
      So we will PodSpec Upload succeeded , And then we were in cocoapod You can also add our new third-party library .
    • This method is actually uploading the description file to cocoapods stay github In the warehouse above , Warehouse address
    • Then you need to wait for the review , Follow pull request equally , The author's consent is required

• Step four , Update local pod Third party framework information data source
  pod setup

• Step five , Use pod search Command to search your own frame , If you can search , Then it means that the audit has passed
