當(dāng)我們?yōu)锳pp工程導(dǎo)入第三方庫的時候經(jīng)常用到CocoaPods這個工具卧檐，這篇文章就介紹安裝CocoaPods的詳細(xì)記錄。
附：筆者介紹另一種導(dǎo)入第三方庫工具Carthage的文章焰宣，可以另外點(diǎn)擊進(jìn)入查看http://www.reibang.com/p/1de99aeedbf6
1.給Mac安裝Ruby環(huán)境
1.1 首先要安裝好RVM
$ curl -sSL https://get.rvm.io | bash -s stable
miki:~ ChenMan$ curl -sSL https://get.rvm.io | bash -s stable
Downloading https://github.com/rvm/rvm/archive/1.29.1.tar.gz
Downloading https://github.com/rvm/rvm/releases/download/1.29.1/1.29.1.tar.gz.asc
Found PGP signature at: 'https://github.com/rvm/rvm/releases/download/1.29.1/1.29.1.tar.gz.asc',
but no GPG software exists to validate it, skipping.
Installing RVM to /Users/admin/.rvm/
Adding rvm PATH line to /Users/admin/.profile /Users/admin/.mkshrc /Users/admin/.bashrc /Users/admin/.zshrc.
Adding rvm loading line to /Users/admin/.profile /Users/admin/.bash_profile /Users/admin/.zlogin.
Installation of RVM in /Users/admin/.rvm/ is almost complete:
* To start using RVM you need to run `source /Users/admin/.rvm/scripts/rvm`
in all your open shell windows, in rare cases you need to reopen all shell windows.
# admin,
#
# Thank you for using RVM!
# We sincerely hope that RVM helps to make your life easier and more enjoyable!!!
#
# ~Wayne, Michal & team.
In case of problems: https://rvm.io/help and https://twitter.com/rvm_io
```
1.2 然后霉囚，載入 RVM 環(huán)境：
> $ source ~/.rvm/scripts/rvm
1.3 修改 RVM 下載 Ruby 的源，到 Ruby China 的鏡像:
> $ echo "ruby_url=https://cache.ruby-china.org/pub/ruby" > ~/.rvm/user/db
1.4 檢查一下是否安裝正確
> $ rvm -v
```
miki:~ ChenMan$ rvm -v
rvm 1.29.2 (latest) by Michal Papis, Piotr Kuczynski, Wayne E. Seguin [https://rvm.io/]
```
1.5 安裝ruby
列出ruby可安裝的版本信息
> $ rvm list known
```
miki:~ ChenMan$ rvm list known

1.6 安裝一個ruby版本
> $ rvm install 2.4.0
```
miki:~ ChenMan$ rvm install 2.4.0
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.12/x86_64/ruby-2.4.0.

```
1.7 如果想設(shè)置為默認(rèn)版本宛徊，可以用這條命令來完成
> $ rvm use 2.4.0 --default
```
miki:~ ChenMan$ rvm use 2.4.0 --default
Using /Users/ChenMan/.rvm/gems/ruby-2.4.0
```
1.8 修改 gem 鏡像
- 查看數(shù)據(jù)源：
> $ gem sources -l
```
miki:~ ChenMan$ gem sources -l
*** CURRENT SOURCES ***
https://ruby.taobao.org/
```
- 更換數(shù)據(jù)源
> $ gem sources --add https://gems.ruby-china.org/ --remove https://ruby.taobao.org/
```
miki:~ ChenMan$ gem sources --add https://gems.ruby-china.org/ --remove https://ruby.taobao.org/
https://gems.ruby-china.org/ added to sources
https://ruby.taobao.org/ removed from sources
```
- 再次查看確認(rèn)數(shù)據(jù)源：
```
miki:~ ChenMan$ gem sources -l
*** CURRENT SOURCES ***
https://gems.ruby-china.org/
```
- 更新gem
```
miki:~ ChenMan$ sudo gem update --system
Password:
Latest version currently installed. Aborting.
```

CocoaPods 1.3.0.beta.2 is available.
To update use: `gem install cocoapods --pre`
[!] This is a test version we'd love you to try.

Setup completed
```
### 3.使用CocoaPods
3.1 創(chuàng)建Xcode工程并切換到該工程路徑
```
$ cd /Users/ChenMan/iOSTest/008String_Test/test321
```
3.2 使用命令pod init在當(dāng)前文件夾下生成一個Podfile文件
```
$ pod init
```
3.3 編輯該文件佛嬉，在該文件中輸入如下信息：
```
# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'
target 'test321' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!
# Pods for test321
pod 'SDWebImage', '~>3.8'
pod "AFNetworking", "~> 2.5.4"
pod 'KVNProgress'
pod 'FMDB'
target 'test321Tests' do
inherit! :search_paths
# Pods for testing
end
target 'test321UITests' do
inherit! :search_paths
# Pods for testing
end
end
```
> 其中，該文件中的命令格式為：`pod '第三庫名稱', '版本號'`闸天。第三庫名稱，名稱一定要正確斜做，不然有可能安裝失敗苞氮。
- 版本號標(biāo)識區(qū)別:
> \>= 1.0 至少版本為1.0
~> 1.0 兼容1.0版本的最新版
== 1.0或1.0 都表示指定版本
3.4 安裝工程依賴的第三方庫
> $ pod install
```
miki:test321 ChenMan$ pod install
Analyzing dependencies
Downloading dependencies
Installing SDWebImage (3.8.2)
Generating Pods project
Integrating client project
[!] Please close any current Xcode sessions and use `test321.xcworkspace` for this project from now on.
Sending stats
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.
[!] Automatically assigning platform ios with version 10.3 on target test321 because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.
```
若出現(xiàn)`pods installed`字樣表示安裝成功。
3.5 關(guān)閉Xcode工程瓤逼，打開.xcworkspace文件笼吟。
3.6 在工程中導(dǎo)入第三庫文件库物，只需要`#import <AFNetworking.h>`類似的即可，開啟CocoaPods之旅贷帮。
