cocoapod创建私有 pods 遇到的问题

1、创建 Repo

$ pod repo add REPO_NAME SOURCE_URL

$ pod repo push REPO_NAME SPEC_NAME.podspec

2、删除 REPO

pod repo remove [name]

二、创建 仓库 Spec。
1、

pod lib create SPEC_NAME
例如：
pod lib create 
DDJSON.podspec

2、修改 *****.podspec

#
# Be sure to run `pod lib lint DDJSON.podspec' to ensure this is a
# valid spec before submitting.
#
# Any lines starting with a 
# are optional, but their use is encouraged
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#

Pod::Spec.new do |s|
  s.name             = 'DDJSON'  
  s.version          = '0.1.0'
  s.summary          = 'DDJSON.'
# This description is used to generate tags and improve search results.
#   * Think: What does it do? Why did you write it? What is the focus?
#   * Try to keep it short, snappy and to the point.
#   * Write the description between the DESC delimiters below.
#   * Finally, don't worry about the indent, CocoaPods strips it!       

  s.description      = <<-DESC
                   
DESC 

  s.homepage         =   
# s.screenshots     =  
  s.license          = { :type => 'MIT', :file => 'LICENSE' }
  s.author           = { ‘***' =>  }
  s.source           = { :git =>  :tag => s.version.to_s }
  # s.social_media_url = 
  s.ios.deployment_target = '7.0'

# 重点要修改，默认的 s.source_files = 'DDJSON/**/*’，会报 “undefined method `path' for nil:NilClass
”错误。
  s.source_files = 'DDJSON/**/*.{c,h,hh,m,mm}'s.public_header_files = 'DDJSON/**/*.h'
  # s.resource_bundles = {
  #   'DDJSON' => ['DDJSON/Assets/*.png']
  #  数据库文件必须要加载 resource 里面，否则 pod install 不会加载到。
  'DDUserTracking' => ['DDUserTracking/*.{xcdatamodeld,xcdatamodel}'] 
  # }

  # s.frameworks = 'UIKit', 'MapKit'
  # CoreData 必须添加引用。
  s.frameworks = 'Foundation', 'CoreData','UIKit'
  # s.dependency 'AFNetworking', '~> 2.3'end

3、验证

pod lib lint

遇到的问题：
1）“- ERROR | [iOS] unknown: Encountered an unknown error (undefined method `path' for nil:NilClass) during validation.”

IMO this is a configuration error, although we should handle it more gracefully. It's a configuration error because we're saying that a resource is a source file, which it's not. The easy fix here is to change s.source_files = 'Pod/Classes//'
to be something like s.source_files = 'Pod/Classes//.{c,h,hh,m,mm}'.

2）``“Encountered an unknown error (Simulator iPhone 4s is not available.) during validation.”``

    升级 cocoapods，“sudo gem install -n /usr/local/bin cocoapods”

4、发布

# 发布到 github。

$ pod trunk register orta@cocoapods.org 'Orta Therox' --description='macbook air’

# 发布到私有库

pod repo push REPO [NAME.podspec].

# Adding other people as contributors

$ pod trunk add-owner ARAnalytics kyle@cocoapods.org

5、私有库 中 引用私有库

即在Podspec
文件中依赖(dependency)私有库
这种情况就比较麻烦一点，因为毕竟Podspec
文件中并没有指明私有仓库地址的地方。那么肯定就不在Podspec
文件里面指明私有仓库的地方。而是在验证和上传私有库的时候进行指明。即在下面这两条命令中进行指明：

pod lib lint 项目名.podspec 

pod repo push REPO  项目名.podspec

6、删除某一个 podspec
只需要到私有REPO 目录下删除 podspec 即可

cd ~/.cocoapods/repos/DDSpecs
rm -Rf PodTestLibrary

# 任何推送到远端

git add —all .
git ci -m 
"remove unuseful pods"

git push origin master
