以前常用VS的 Nuget管理项目的外部类库与一些小插件。在xocde里有类似的东西，它就是Cocopods。

如何安装Cocopods

Get Start

上面的内容是在pods里搜索，在xcode的项目目录的一个叫Podfile的文件中列出依赖项
Search for pods (above). Then list the dependencies in a text file named Podfile in your Xcode project directory:

platform :ios, '8.0'
use_frameworks!

target 'MyApp' do
  pod 'AFNetworking', '~> 2.6'
  pod 'ORStackView', '~> 3.0'
  pod 'SwiftyJSON', '~> 2.3'
end

提示：CocoaPods提供了一个pod init命令来创建一个灵活的默认Podfile，你会用到它的。
Tip: CocoaPods provides a pod init command to create a Podfile with smart defaults. You should use it.

现在你可以在项目里安装依赖项了
Now you can install the dependencies in your project:

1	$ pod install

确保在构建项目时始终打开Xcode工作区(xcworkspace文件)而不是项目文件：
Make sure to always open the Xcode workspace instead of the project file when building your project:

1	$ open App.xcworkspace

现在您可以导入依赖关系，例如：
Now you can import your dependencies e.g.:

1	#import <Reachability/Reachability.h>

基础命令

Usage:

    $ pod COMMAND

      CocoaPods, the Cocoa library package manager.

Commands:

    + cache      Manipulate the CocoaPods cache
    + env        Display pod environment
    + init       Generate a Podfile for the current directory
    + install    Install project dependencies according to versions from a
                 Podfile.lock
    + ipc        Inter-process communication
    + lib        Develop pods
    + list       List pods
    + outdated   Show outdated project dependencies
    + repo       Manage spec-repositories
    + setup      Setup the CocoaPods environment
    + spec       Manage pod specs
    + update     Update outdated project dependencies and create new
                 Podfile.lock

Options:

    --silent     Show nothing
    --version    Show the version of the tool
    --verbose    Show more debugging information
    --no-ansi    Show output without ANSI codes
    --help       Show help banner of specified command
	from /Library/Ruby/Gems/2.0.0/gems/cocoapods-1.2.0/lib/cocoapods/command.rb:47:in `run'
	from /Library/Ruby/Gems/2.0.0/gems/cocoapods-1.2.0/bin/pod:55:in `<top (required)>'
	from /usr/local/bin/pod:23:in `load'
	from /usr/local/bin/pod:23:in `<main>'

为自己的开源项目添加pod支持

iOS开发– 创建podspec文件，为自己的项目添加pod支持

Setup报错

1 2	$ git config --global http.postBuffer 24288000 $ git config --list

若输出 http.postbuffer=24288000, 就 OK了

cocoapods:常见错误总结

可视化CocoaPods

我使用 alcatraz来可视化CocoaPods操作。因为有时候用命令行不是很方便。

安装命令如下：

1	curl -fsSL https://raw.githubusercontent.com/supermarin/Alcatraz/deploy/Scripts/install.sh \| sh

卸载命令如下：

1 2	rm -rf ~/Library/Application\ Support/Developer/Shared/Xcode/Plug-ins/Alcatraz.xcplugin rm -rf ~/Library/Application\ Support/Alcatraz

XCode 8.X 需要 usign 才能使用插件

解决插件升级不能使用的问题

在xcode版本更新的之后，或者从package manager新下载了插件，有时候不可用。这时候就需要找到下面目录
~/Library/Application Support/Developer/Shared/Xcode/Plug-ins
然后找到新下载的插件 ShowContent 。打开plist文件，在DVTPlugInCompatibilityUUIDs列表中新增一串ID。

下面是这串ID的获取方法：

1	defaults read /Applications/Xcode.app/Contents/Info DVTPlugInCompatibilityUUID
