流程 Process

Workflow

Begin With Milestone

• ⺫⽬目标

• 功能

• 责任

• 依赖

• ⻛风险

• MRD

One Feature, One Branch

开发就像打怪，怪物就是issues

重构永⽆无⽌止境

以Code Reviewer姿态对待你的代码

How to make reviewers life harder

• large commits

• reformatting of code

• lots of refactoring

• omit issue number when committing

Git Flow Workflowhttps://www.atlassian.com/git/tutorials/comparing-workflows/feature-branch-workflow

Telling Stories With Your Git History

• ⼀一个 commit 只做⼀一件事情，⽐比如⼀一个 feature，⼀一个bugfix

• 每个 commit 的粒度不要太⼤大，⼤大型 feature 分解成多个⼦子 feature 做多个 commit

• git push 之前在本地进⾏行 git rebase

• 每个 commit 需要撰写详尽的 commit message，相关 issue 需要注明 issue number。关闭对应 issue，需要注明 close #issue-number.

Light View Controllers• Move Domain Logic into the Model

• Move View Code into the View Layer

• Separate Out Data Source and Other Protocols

• Creating the Store Class

• Move Web Service Logic to the Model Layer

• Communicationhttp://www.objc.io/issues/1-view-controllers/lighter-view-controllers/

VIPERSingle Responsibility Principle

VIPER• View (UserInterface)

• Presenter

• Interactor

• Entity

• Routing (Wireframe)

VIPER Checklist• Views and view controllers receive user interactions and pass

them to Presenters for decision making

• Presenters contain the view logics and prepare content for display and reacting to user inputs

• Presenters should not know about the existence of all UIViews

• Interactors contain business logics and they should be independent of UI

• Entities are model objects only manipulated by Interactors

• Wireframe is the only place to define screen navigations and their transition animations

Benefits of VIPER• Easy to iterate on

• Collaboration friendly

• Separated out concerns

• Spec-ability

• Vipergen

Other Frameworks

• AOP (Aspects)

• DeepLink (DeepLinkKit)

• AutoLayout (Masonry)

• Logging (CocoaLumberjack)
