Create a Podfile file

I. Summary

When iOS is developed, many third-party libraries are referenced in the project, and CocoaPods (https://github.com/CocoaPods/CocoaPods) can be used to manage these third-party libraries conveniently and uniformly.

Second, installation

As the online tutorials are basically similar, but the details are not very perfect, so the opportunity will be added here:

Note: To use Cocoapods, download and install it, and download and install cocoapods requires a ruby environment

1. Building Ruby Environment

The current installation environment is Mac mini 10.8.5. The Mac OS itself comes with Ruby, but it's still an update, because the first time I installed it failed without updating Ruby.

A view the current Ruby version: Open the terminal input ruby-v (yes, but with this version the next work fails, so update under Ruby)

[OBJC] view plain copy print? Ritekimac-mini:podtest lucky$ ruby-v Ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0] RitekiMac-mini:Pod Test lucky$
b Update Ruby

Terminal Enter the following command (point the Ruby image to Taobao, avoid being the wall, you know)

Gem Sources--remove https://rubygems.org/
Gem Sources-a https://ruby.taobao.org/
Gem sources-l (used to check for successful use of alternate mirror locations)

[OBJC] view plain copy print? ritekimac-mini:~ lucky$ gem sources--remove https://rubygems.org/https://rubygems.org/removed from sources Ritekima c-mini:~ lucky$ gem sources-a https://ruby.taobao.org/https://ruby.taobao.org/added to sources ritekimac-mini:~ Luc ky$ Gem SOURCES-L * * * * Current SOURCES * * *

2. Download and install CocoaPods

Terminal input: sudo gem install cocoapods

[HTML]  View plain copy print? ritekimac-mini:~ lucky$ sudo gem install cocoapods      CHANGELOG:       ## 0.32.1      ##### bug fixes       * fixed the podfile  ' Default_subspec '  attribute in nested  subspecs.       [Fabio Pelosin][irrationalfab]    \ [# 2050] (https://github.com/CocoaPods/CocoaPods/issues/2050)          successfully  installed cocoapods-0.32.1   installing ri documentation for  cocoapods-0.32.1  /system/library/frameworks/ruby.framework/versions/1.8/usr/lib/ruby/1.8/rdoc/ rdoc.rb:280: warning: conflicting chdir during another chdir block   /system/library/frameworks/ruby.framework/versions/1.8/usr/lib/ruby/1.8/rdoc/rdoc.rb:287: warning: conflicting chdir during another chdir block   Done installing  documentation for cocoapods after 10 seconds   1 gem  installed  

This will download and install the Cocoapods

3. Using Cocoapods

A Create a new project, name Podtest

b terminal, CD-to-project directory (note: The head record containing the Podtest folder, Podtest.xcodeproj, Podtesttest)
