Cocoapods 更新

cocoapods出现了问题

Q1:

The dependency `` is not used in any concrete target

终端.png

是说没有可用的target

主要是升级之后的cocoapods语法方面出现了变化

之前版本的podfile

platform :iOS, '8.0'
  pod 'AFNetworking', '~> 2.6.0'

这样写就可以了，然后升级之后需要把podfile之中改成以下：

platform :ios, '8.0'
target ‘EasyPark’ do
  pod 'AFNetworking', '~> 2.6.0'
end

嗯，之后顺便升级了下pod，改了下默认源
1.移除现有默认源

gem sources --remove https://rubygems.org/

2.使用新源氏

gem sources -a https://ruby.taobao.org/

3.安装Cocospods

sudo gem install -n /usr/local/bin cocoapods

 pod setup

4.更新gem

sudo gem update --system
