Setting up CocoaPods master repo
CocoaPods 1.1.0.rc.2 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.
For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.1.0.rc.2
Setup completed
附：如何使用CocoaPods的镜像索引:
所有项目的Podspec文件都托管在https://github.com/CocoaPods/Specs,第一次执行pod setup时,CocoaPods会将这些podspec索引文件更新到本地的~/.cocoapods目录下,这个索引文件比较大,所以第一次更新时非常慢.友好人士在国内的服务器建立了Cocoapods索引库的镜像,所以执行索引跟新操作时候会快很多.具体操作方法如下:$ pod repo remove master$ pod repo add master https://gitcafe.com/akuandev/Specs.git$ pod repo update这是使用gitcafe上的镜像,将以上代码中的 https://gitcafe.com/akuandev/Specs.git替换成 https://git.oschina.net/akuandev/Specs.git 即可使用oschina上的镜像。
更为取巧的办法为：
git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
