搜索

安装好后，就可以使用search命令来搜索你想要的library,例如：

$ pod search JSONKit

-> JSONKit (1.5pre)
   A Very High Performance Objective-C JSON Library.
   - Homepage: https://github.com/johnezang/JSONKit
   - Source:   https://github.com/johnezang/JSONKit.git
   - Versions: 1.5pre, 1.4 [master repo]

应用

以下通过一个实例演示，如何在一个xcode项目中使用pod

首先创建一个xcode项目，名字叫CocoaPodsTest，然后cd到工程所在目录ls一下

$ ls
CocoaPodsTest		CocoaPodsTest.xcodeproj
$ pod install
[!] No `Podfile' found in the current working directory.
$ sudo touch Podfile
Password:
$ vi Podfile

添加以下内容，保存退出
platform :ios
pod 'JSONKit'
$ pod install
Analyzing dependencies
Downloading dependencies
Installing JSONKit (1.5pre)
Generating Pods project
Integrating client project

[!] From now on use `CocoaPodsTest.xcworkspace`.

$ ls
CocoaPodsTest			CocoaPodsTest.xcworkspace	Podfile.lock
CocoaPodsTest.xcodeproj		Podfile				Pods
$ pod update
Analyzing dependencies
Downloading dependencies
Using JSONKit (1.5pre)
Generating Pods project
Integrating client project

现在通过双击CocoaPodsTest.xcworkspace打开项目就可以了；）

如果在使用import找不到头文件，需要再target里设置User Header Search Path为${SRCROOT}，同时选择recursive。
