最佳实战：采用CocoaPods配置管理第三方库

标签：

书接上文（CocoaPods / Pod 安装简略步骤），在本地安装了CocoaPods之后，我们就开始配置工程和添加第三方库让pod管理，下面就进行实战操作，让pod配置变的如此简单（标注-红色为我们手动输入，黑色为命令行自己输出）：

第一步：验证是否pod安装成功

ZPodsDemo mapboo$ pod --version

0.38.2

第二步：创建工程项目，和平时一样，然后打开终端进入该工程根目录

~ mapboo$ cd /Users/mapboo/Desktop/ZPodsDemo 

ZPodsDemo mapboo$ ls

ZPodsDemo ZPodsDemo.xcodeproj ZPodsDemoTests

第三步：创建pod管理配置文件

ZPodsDemo mapboo$ touch Podfile

ZPodsDemo mapboo$ ls -a

. PodfileZPodsDemoTests

.. ZPodsDemo

.DS_Store ZPodsDemo.xcodeproj

注意：多了Podfile文件在根目录

第四步：搜索需要添加的第三方库JSONKit

ZPodsDemo mapboo$ pod search JSONKit

-> GCJSONKit (1.5.0)

   GC‘s fork of a Very High Performance Objective-C JSON Library.

   pod ‘GCJSONKit‘, ‘~> 1.5.0‘

   - Homepage: https://github.com/gamechanger/JSONKit

   - Source:   https://github.com/gamechanger/JSONKit.git

   - Versions: 1.5.0 [master repo]

-> JSONKit (1.5pre)

   A Very High Performance Objective-C JSON Library.

   pod ‘JSONKit‘, ‘~> 1.5pre‘

   - Homepage: https://github.com/johnezang/JSONKit

   - Source:   https://github.com/johnezang/JSONKit.git

   - Versions: 1.5pre, 1.4 [master repo]

-> JSONKit-NoWarning (1.2)

   A Very High Performance Objective-C JSON Library.

   pod ‘JSONKit-NoWarning‘, ‘~> 1.2‘

   - Homepage: https://github.com/ignazioc/JSONKit-NoWarning

   - Source:   https://github.com/ignazioc/JSONKit-NoWarning.git

   - Versions: 1.2, 1.1 [master repo]

-> SGJsonKit (1.2.4)

   Auto-mapping json objects to Objective-C classes

   pod ‘SGJsonKit‘, ‘~> 1.2.4‘

   - Homepage: http://github.com/dongminkim/SGJsonKit

   - Source:   https://github.com/dongminkim/SGJsonKit.git

   - Versions: 1.2.4, 1.2.3, 1.2.2, 1.2.1, 1.2, 1.1.1, 1.1, 1.0 [master repo]

第五步：打开Podfile文件，可以在终端用vim或直接在项目中右键文本中打开，输入如下代码

platform :ios  

pod ‘JSONKit‘, ‘~> 1.5pre’

第六步：开始安装该第三方库

ZPodsDemo mapboo$ pod install --verbose --no-repo-update

  Preparing

[!] Unable to load a specification for the plugin `/Library/Ruby/Gems/2.0.0/gems/cocoapods-try-release-fix-0.1.2`

Analyzing dependencies

Inspecting targets to integrate

  Using `ARCHS` setting to build architectures of target `Pods`: (``)

Resolving dependencies of `Podfile`

Comparing resolved specification to the sandbox manifest

  A JSONKit

Downloading dependencies

-> Installing JSONKit (1.5pre)

  > Copying JSONKit from

  `/Users/mapboo/Library/Caches/CocoaPods/Pods/Release/JSONKit/1.5pre-efef3` to

  `Pods/JSONKit`

  - Running pre install hooks

Generating Pods project

  - Creating Pods project

  - Adding source files to Pods project

  - Adding frameworks to Pods project

  - Adding libraries to Pods project

  - Adding resources to Pods project

  - Linking headers

  - Installing targets

    - Installing target `JSONKit` iOS 4.3

    - Installing target `Pods` iOS 4.3

  - Running post install hooks

  - Writing Xcode project file to `Pods/Pods.xcodeproj`

  - Writing Lockfile in `Podfile.lock`

  - Writing Manifest in `Pods/Manifest.lock`

Integrating client project

[!] Please close any current Xcode sessions and use `ZPodsDemo.xcworkspace` for this project from now on.

Integrating target `Pods` (`ZPodsDemo.xcodeproj` project)

  Adding Build Phase ‘Copy Pods Resources‘ to project.

  Adding Build Phase ‘Check Pods Manifest.lock‘ to project.

  - Running post install hooks

    - cocoapods-stats from

    `/Library/Ruby/Gems/2.0.0/gems/cocoapods-stats-0.5.3/lib/cocoapods_plugin.rb`

Sending stats

      - JSONKit, 1.5pre

      Failed to send stats:  SSL_connect returned=1 errno=0 state=SSLv2/v3 read

      server hello A: sslv3 alert handshake failure

安装完成后再看项目目录如下：

第六步：配置第三方库路径，源项目就可以引入相对路径头文件

${SRCROOT}    recursive

如图配置

前后对比

第七步：更改第三方库

如果有修改、更新或添加第三方库，可以直接打开Podfile文件，例如输入如下：

platform :ios  

pod ‘Reachability‘,  ‘~> 3.0.0’

然后再次运行命令

ZPodsDemo mapboo$ pod install --verbose --no-repo-update

就等于删除了之前的JSONKit库，新增了Reachability库

第八步：打开项目双击ZPodsDemo.xcworkspace即可开始正常开发；

至此，我们完整的实战操作了一次pod管理第三方库的全部流程，再也不用担心第三方库的更新问题了，大家好，我是Z，下次再见，更多优秀博文，可下载IT面试宝典-博文推荐栏目下阅读。
