从Carthage迁到CocoaPods

我在公司的废弃项目上做改造。点击查看项目。

创建podfile

终端cd到工程根目录，执行命令:

pod init

然后用open命令打开podfile文件:

open podfile

以下是默认生成的文件内容：

# Uncomment the next line to define a global platform for your project
# platform :ios, '9.0'

target 'Syiar' do
  # Comment the next line if you don't want to use dynamic frameworks
  use_frameworks!

  # Pods for Syiar

  target 'SyiarTests' do
    inherit! :search_paths
    # Pods for testing
  end

  target 'SyiarUITests' do
    # Pods for testing
  end

end

导入AFNetworking

先单独尝试集成AFNetworking

修改podfile，添加下面一行：

  # Pods for Syiar
  pod 'AFNetworking', '~> 3.0'

然后回到终端，执行安装命令：

pod install

成功后会生成xcworkspace文件：

[!] Please close any current Xcode sessions and use `Syiar.xcworkspace` for this project from now on.
Pod installation complete! There is 1 dependency from the Podfile and 1 total pod installed.

有时候也会伴随一些警告。我碰到三条警告：

[!] Automatically assigning platform `iOS` with version `9.0` on target `Syiar` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

[!] The `Syiar [Debug]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods-Syiar/Pods-Syiar.debug.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The `Syiar [Release]` target overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Target Support Files/Pods-Syiar/Pods-Syiar.release.xcconfig'. This can lead to problems with the CocoaPods installation
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

第一条是提醒我们指定platform。打开podfile，发现已经默认添加了，但是需要取消注释：

platform :ios, '9.0'

后面两条需要我们打开新生成的xcworkspace - 如果之前打开了工程要先关闭。

然后在Build Settings找到other linker flags，将里面原有的删除，添加$(inherited)。Xcode会自动展开成需要的。

会到终端，再执行一次pod install。警告消失了。

然后在Xcode中删除之前Carthage导入的framework。再在Build Phases 下查找有无 包含以下内容的 Run Script：

/usr/local/bin/carthage copy-frameworks

如果有，删除Input Files中的AFNetworking：

$(SRCROOT)/Carthage/Build/iOS/AFNetworking.framework

Xcode编译，成功。

导入其他库

在podfile中添加其他需要导入的库。我添加了下面这些：

  pod 'YYModel'
  pod 'Masonry'
  pod 'SDWebImage'
  pod 'MBProgressHUD'
  pod 'SSZipArchive'

然后回到终端，执行安装命令：

pod install

完成后回到Xcode删除对应的framework。

整个删除前文提到Run Script脚本。去到工程目录，删掉Carfile、Carfile.resolved、Carthage/文件夹。

ZipArchive这个库的引入方式需要修改一下：

#import 

最后将Pods/文件夹加入到.gitingore中：

# CocoaPods
#
# We recommend against adding the Pods directory to your .gitignore. However
# you should judge for yourself, the pros and cons are mentioned at:
# https://guides.cocoapods.org/using/using-cocoapods.html#should-i-check-the-pods-directory-into-source-control
#
Pods/

完成。
