我对CocoaPods的使用

CocoaPods 是 iOS 常用的著名的类库管理工具,使用 Xcode 的时候用 CocoaPods 来管理第三方框架很方便

补充CocoaPods更新
sudo gem install -n /usr/local/bin cocoapods –pre

安装步骤

1.添加源
$ sudo gem sources -a https://ruby.taobao.org/
2.删除源
$ sudo gem sources -r https://rubygems.org/
3.验证新源是否替换成功
$ gem sources -l

gem 的服务器在国外,因此国内想安装 CocoaPods 需要翻墙,惊恐, 但是大笑.国内的淘宝已经做了贡献 https://ruby.taobao.org 这是一个完整 rubygems.org 镜像，频率为15分钟一次。我们需要镜像的可以快速的访问.
code4app 上就写成了 http. 记住了是 https

4.安装 CocoaPods
$ sudo gem install cocoapods --pre

$ pod setup

注意：苹果系统升级 OS X EL Capitan后安装改为:

$ sudo gem install -n /usr/local/bin cocoa pods

$ pod setup

添加第三方框架步骤

1.打开终端 输入 $ cd 进入工程名

          输入 $ touch Podfile  将Podfile文件拖入Xcode ,并输入 
          platform :ios, '8.0'
          target 'xxxDemo' do
         
          pod 'AFNetworking'
          pod 'SDWebImage'

          end

2.输入$ pod install

          如果太慢可以尝试： $ pod install --verbose --no-repo-update

gem 的常用命令如下
查看gem源
$ gem sources –l

gem自身升级
$ sudo gem update --system

查看版本
$ gem --version

清除过期的gem
$ sudo gem cleanup

安装包
$ sudo gem install cocoa pods

删除包
$ gem uninstall cocoa pods

更新包
$ sudo gem update

列出本地安装的包
$ gem list

pod的常用命令

创建默认的 Podfile
$ pod init

第一次使用安装框架
$ pod install

安装框架，不更新本地索引，速度快
$ pod install --no-repo-update

今后升级、添加、删除框架，或者框架不好用都使用这个命令
$ pod update

更新框架，不更新本地索引，速度快
$ pod update --no-repo-update

搜索框架
$ pod search XXX

帮助
$ pod --help

可能遇到的错误提示及解决方法：

Error 1：

Error fetching http://ruby.taobao.org/:
bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)
解决方案：把安装流程中 $ gem sources -a http://ruby.taobao.org/
改为：$ gem sources -a https://ruby.taobao.org/

Error 2：

ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/pod
解决方案：苹果系统升级 OS X EL Capitan 后会出现的插件错误，将安装流程 安装 CocoaPods 的 sudo gem install cocoapods
改为 sudo gem install -n /usr/local/bin cocoapods

Error 3：

[!] Unable to satisfy the following requirements:

• AFNetworking (~> 2.3.1) required by Podfile
  Specs satisfying the AFNetworking (~> 2.3.1) dependency were found, but they required a higher minimum deployment target.

解决方案：Podfile 文件 中 platform:ios, ‘8.0’ 后边的 8.0 是平台版本号 ，一定要加上

Error4:
