iOS 简单给项目添加pod

老是会忘，毕竟不会频繁新建项目。以前怎么弄得也忘得差不多了，曾经有段时间习惯使用Xcode的CocoaPods插件来安装，后来Xcode不支持插件了，就用终端来安装，代码这种东西，学而不时习之，就是会忘。

1. 新建工程 PodTest

2. 打开终端，cd到 PodTest 根目录

3. 在终端输入 "pod init"，会自动创建一个名为 Podfile 的文件

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'PosTest' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for PosTest

  target 'PosTestTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'PosTestUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

4. 编辑 Podfile 文件

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'PosTest' do
  # Uncomment the next line if you're using Swift or would like to use dynamic frameworks
  # use_frameworks!

  # Pods for PosTest

  pod 'SVProgressHUD', :git => 'https://github.com/SVProgressHUD/SVProgressHUD.git'

  target 'PosTestTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'PosTestUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

5. 在终端输入 "pod install"，等待下载完成。

pod install

6. 回到工程目录，双击“PosTest.xcworkspace”进入程序

以下是整个终端输入的代码：

WinsondeMacBook-Pro:PosTest Winson_microlink$ pod init

Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

[!] Automatically assigning platform ios with version 11.0 on target PosTest because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.
