1.安装主要看唐巧这一篇文章

2.解决update/install超慢的问题看着一篇文章

在使用过程中遇到的一些问题:

1.在执行pod install命令时, 提示本机coocopods版本老旧:

bogon:ADPhotoBrowser LittleP$ pod install
Updating local specs repositories
[!] The `master` repo requires CocoaPods 1.0.0 -  (currently using 0.39.0)
Update CocoaPods, or checkout the appropriate tag in the repo.

[!] Your Podfile has had smart quotes sanitised. To avoid issues in the future, you should not use TextEdit for editing it. If you are not using TextEdit, you should turn off smart quotes in your editor of choice.

如何解决:
第一步, 当然是cocoapods进行版本更新sudo gem install cocoapods, 遇到新问题:

bogon:ADPhotoBrowser LittleP$ sudo gem install cocoapods
Password:***
ERROR:  While executing gem ... (Gem::DependencyError)
    Unable to resolve dependencies: cocoapods requires cocoapods-core (= 1.5.0), cocoapods-deintegrate (< 2.0, >= 1.0.2), cocoapods-downloader (< 2.0, >= 1.2.0), molinillo (~> 0.6.5), xcodeproj (< 2.0, >= 1.5.7)

解决办法是把本地gem更新到最新版本sudo gem update --system
更新完成后继续执行sudo gem install cocoapods

bogon:ADPhotoBrowser LittleP$ sudo gem install cocoapods

遇到新的问题

更改gem cocoapods更新命令为sudo gem install -n /usr/local/bin cocoapods后:
