往项目里面添加文件,文件夹的时候Create groups和Create folder references的区别
Create groups
:在创建文件夹之后,其实只是创建了一个虚拟目录,便于组织文件,在实际安装的时候,会把文件夹下面的文件都放到应用程序根目录
Create folder references
:这个就是真实的创建了文件夹了
感觉Create groups
是个很方便的东西啊,在新建项目的时候勾选这个话,之后在项目里面改变位置也不会有什么问题

1.初始化pod
,进入到项目的目录下执行
pod init
执行完成之后会出现Podfile
文件
2.编辑Podfile
文件
# Uncomment this line to define a global platform for your project
# platform :ios, '8.0'
# Uncomment this line if you're using Swift
# use_frameworks!
target 'MagicBox' do
platform:ios,'7.0'#所有库支持的ios最低版本
pod 'AFNetworking','~>2.3.1'#开源库版本号
pod 'SVProgressHUD','~>1.0'
pod 'Cordova','~>3.5.0'
pod 'GCJSONKit','~>1.5.0'
pod 'CordovaPlugin-console','~>0.2.10'
pod 'CordovaPlugin-device','~>0.2.11'
pod 'CordovaPlugin-network-information','~>0.2.3'
end
target 'MagicBoxTests' do
end
target 'MagicBoxUITests' do
end
3.安装开源库
pod install
执行成功之后会显示

4.打开创建的DemoApp.xcworkspace
,在桥接文件里面加入引入库文件的代码即可
