网上说,pod install会按照 pod 文件指定的版本安装,而pod update会安装最新版本,那么问题来了。

举个例子:

//使用大于等于0.1.2,小于0.2的版本
pod ‘AFNetworking’, ‘~>0.1.2′   

如果我现在的版本是0.1.2,最新版本是1.1.0,中间还有一个版本是0.1.9,那么pod install是哪个版本,pod update是哪个版本?

The following takes version 1.1.0.rc.2 as an example for explanation.
You can view the installed version via pod env.

   CocoaPods : 1.1.0.rc.2
        Ruby : ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin15]
    RubyGems : 2.5.1
        Host : Mac OS X 10.11.6 (15G1004)
       Xcode : 8.0 (8A218a)
         Git : git version 2.8.4 (Apple Git-73)
Ruby lib dir : /usr/local/Cellar/ruby/2.3.1/lib
Repositories : master - https://github.com/CocoaPods/Specs.git @ 02982fffbac5c3b22e7b0c2a77515f865f0e1065

Installation Source

Executable Path: /usr/local/bin/pod

Plugins

cocoapods-deintegrate : 1.0.1
cocoapods-plugins     : 1.0.0
cocoapods-search      : 1.0.0
cocoapods-stats       : 1.0.0
cocoapods-trunk       : 1.0.0
cocoapods-try         : 1.1.0

Take pod ‘AFNetworking’, ‘~>0.1.2′ as an example

pod install 首先会检查 Podfile.lock 文件。如果里面的版本号符合该要求,0.1.x,比如是 0.1.3,则会按照指定的版本号进行安装。如果不符合,比如指定了 0.2.9,则会安装 0.1.9.

pod update 会忽略 Podfile.lock 文件。直接分析 Podfile file to install.

pod install, if it has not been installed before, the latest version of the restriction will be installed; if it has been installed, it will be the previously installed version.
pod update, the latest version of the restriction is installed.
