初识fastlane

fastlane

fastlane is the easiest way to automate beta deployments and releases for your iOS and Android apps. 🚀 It handles all tedious tasks, like generating screenshots, dealing with code signing, and releasing your application.

举个例子，在项目根目录创建包含以下内容的Fastfile文件：

lane :beta do
  increment_build_number
  build_app
  upload_to_testflight
end

lane :release do
  capture_screenshots
  build_app
  upload_to_app_store       # Upload the screenshots     and the binary to iTunes
  slack                     # Let your team-mates know the     new version is live
end

这是两段fastlane的命令集

然后，需要执行哪段命令只需要 操作命令 fastlane beta/release即可让程序自动有序地执行所有操作。

Getting Started for iOS

Install the latest Xcode command line tools:

xcode-select --install

Install fastlane using

# Using RubyGems
sudo gem install fastlane -NV

# Alternatively using Homebrew
brew cask install fastlane

Navigate to your iOS app and run

fastlane init

fastlane will automatically detect your project, and ask for any missing information.

[✔] Looking for iOS and Android projects in     current directory...
[12:28:02]: Created new folder './fastlane'.

[12:28:02]: -----------------------------
[12:28:02]: fastlane can help you with all kinds of automation for your mobile app
[12:28:02]: We recommend automating one task     first, and then gradually automating more over time
[12:28:02]: What would you like to use fastlane for?
1. 📸  Automate screenshots
2. 👩‍✈️  Automate beta distribution to TestFlight
3. 🚀  Automate App Store distribution
4. 🛠  Manual setup - manually setup your project to automate your tasks

命令执行会生成fastlane文件夹，并需要一步步跟着配置fastlane， 以及根据需求相应地配置该项目设置。
根据用户作出的不同需求选择，会在该文件夹生成不同的配置文件。其中最重要的是fastlane/Fastfile这个文件，里面包含了所有需要配置项目的信息。

比如以上选择了 1. 📸 Automate screenshots则会需求手动配置项目：

[12:31:40]: Parsing your local Xcode project to find     the available schemes and the app identifier
[12:31:40]: $ xcodebuild -showBuildSettings -workspace TestForImage.xcworkspace -scheme   TestForImage
✅  Successfully created SnapshotHelper.swift './fastlane/SnapshotHelper.swift'
✅  Successfully created new Snapfile at './fastlane/Snapfile'
-------------------------------------------------------
Open your Xcode project and make sure to do the     following:
1) Add a new UI Test target to your project
2) Add the ./fastlane/SnapshotHelper.swift to your UI Test target
   You can move the file anywhere you want
3) Call `setupSnapshot(app)` when launching your app

    let app = XCUIApplication()
    setupSnapshot(app)
    app.launch()

4) Add `snapshot("0Launch")` to wherever you want to trigger screenshots
5) Add a new Xcode scheme for the newly created UITest target
6) Add a Check to enable the `Shared` box of the newly created scheme

这时候可以看到fastlane/Fastfile长这样的：

fastlane/Fastfile

里面包含了截图并上传到appstore的相关命令，随后只需要在项目路径下执行fastlane screenshots就可以自动执行这些操作了。

在配置fastlane的过程中，也会自动在项目根目录下生成Gemfile以及Gemfile.lock文件，里面定义了fastlane的版本和依赖，这会提高使用fastlane的速度，这也是官方推荐的。

自定义动作

除了fastlane官方预置的动作外，更多的是使用自定义的适合自己的动作：

自定义fastlane命令集

这里创建了一个build_qa的脚本，使用fastlane build_qa启动执行，进行触发bitrise build qa .ipa的一系列操作。
