react-native-router-flux 使用详解(三)

前端之家收集整理的这篇文章主要介绍了react-native-router-flux 使用详解(三)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

在 上一章http://cherylgood.cn/c/react_native_router_flux_使用详解二.php

我们主要进一步介绍了react-native-router-flux的使用,接下来主要讲解 其主要配置参数和api,当前我主要是翻译官网的学习资料进行学习,我将在后面的章节中实际使用他,通关编写一个rn版的微博apphttp://cherylgood.cn/c/React-Native学习之制作RN版的微博app.php

Available imports

  • Router
  • Scene
  • Modal
  • TabBar
  • getInitialState
  • Reducer
  • DefaultRenderer
  • Switch
  • Actions
  • ActionConst
  • NavBar

Router:

Property Type Default Description
reducer function

optional user-defined reducer for scenes,you may want to use it to intercept all actions and put your custom logic

你可以为scenes定义reducer,你可以通过使用reducer拦截所有的actions并执行你自定义的逻辑代码

createReducer function

function that returns a reducer function for {initialState,scenes} param,you may wrap Reducer(param) with your custom reducer,check Flux usage section below

函数功能:createReducer({initialState,scenes})将返回一个reducer,你可以用你自定义的reduer棒状一个Reducer(param),可以参看下面章节中Flux的用例。

other props

all properties that will be passed to all your scenes

在Router中定义的所有属性都会传入你的scenes组件中

children

required (if no scenes property passed)

当没有children属性被传入时,router必须有子节点

Scene root element 通过children属性定义我们的root元素
scenes object optional 可选

scenes for Router created with Actions.create. This will allow to create all actions BEFORE React processing. If you don't need it you may pass Scene root element as children

因为scenes时Router被创建后通过Actions.create创建的。这将允许我们在React 创建scenes之前创建好所有的actions。如果你不需要你可以使用Scene跟元素作为子节点

getSceneStyle function optional 可选

Optionally override the styles for NavigationCard's Animated.View rendering the scene.

根据需要重写该样式去改变导航卡的动画。

backAndroidHandler function optional 可选

Optionally override the handler forBackAndroid,returntrueto stay in the app or returnfalseto exit the app. Default handler will pop a scene and exit the app at last when the back key is pressed on Android.

可以重写该方法去控制android设备的返回键,返回true时会停留在app内部,返回false时会直接退出app,默认的操作时重栈中出栈栈顶的scene,如果该scene是最后一个,就会退出app。(相信android程序员都很熟悉)

onBackAndroid function optional 可选

Get called after back key is pressed and a scene is poped,won't affect the default behavior.

在返回键被按下且scene弹出后将被调用,不会影响到默认的行为。可以通过该方法做一些弹出后的操作。

onExitApp function optional

Optionally override the default action after back key is pressed on root scene. Returntrueto stay,or returnfalseto exit the app.

可以重写该方法去定义当处于root scene时,返回键被按下后的行为,返回false会退出该app

Scene:

Property Type Default Description
key string required 必须

Will be used to call screen transition,for example,Actions.name(params). Must be unique.

在切换屏幕的时候会使用该key,例如Actions.name(params).key的值必须时唯一的。

component React.Component semi-required

TheComponentto be displayed. Not required when defining a nestedScene,see example. If it is defined for 'container' scene,it will be used as custom containerrenderer

切换到该scene时,component属性定义的组件将被展示出来。当定义一个嵌套scene时不要求有。例如。如果他作为一个scene容器定义。他将被视作一个自定义容器渲染者来使用。

initial bool false

Set totrueif this is the initial scene

如果设置该属性为true,该scene将最为默认初始化scene。你可以理解为进来后进一个看到的scene

type string

ActionConst.PUSH

orActionConst.JUMP

Defines how the new screen is added to the navigator stack. One ofActionConst.PUSH,ActionConst.JUMP,ActionConst.REPLACE,ActionConst.RESET. If parent container is tabbar (tabs=true),ActionConst.JUMPwill be automatically set.

定义如何去创建一个新的屏幕并放入导航栈中。可以是ActionConst.PUSH,AtionConst.JUMP,ActionConst.REPLACK,AtionConst.RESET.如果父容器是一个tabbar且tabs=true,将会自动设置为ActionConst.JUMP.

clone bool

Scenes marked withclonewill be treated as templates and cloned into the current scene's parent when pushed. See example.

在被push的时候,使用clone标识的Scenes将被作为模版处理,并克隆到当前的scene的容器中。

passProps bool false

Pass all own props (except style,key,name,component,tabs) to children. Note that passProps is also passed to children.

将自己所有的属性(except style,key,name,component,tabs)传入到子节点。

ActionConst:

We accept shorthand string literal when defining scene type or action params,like:

在定义scene类型活着action参数时,我们接受间断的字符串文字,例如:

Actions.ROUTE_NAME({type: 'reset'});
<Scene key="myscene" type="replace" >

but it will be converted to const value when pass to reducer. RECOMMENDATION is to always use const instead of string literal for consistency:

但是当传入reducer时,它将被转换成一个静态值,为来一致性,我们推荐总是使用静态的去替换字符串文字

Actions.ROUTE_NAME({type: ActionConst.RESET});
<Scene key="myscene" type={ActionConst.REPLACE} >
Property Type Value Shorthand
ActionConst.JUMP string 'REACT_NATIVE_ROUTER_FLUX_JUMP' 'jump'
ActionConst.PUSH string 'REACT_NATIVE_ROUTER_FLUX_PUSH' 'push'
ActionConst.REPLACE string 'REACT_NATIVE_ROUTER_FLUX_REPLACE' 'replace'
ActionConst.BACK string 'REACT_NATIVE_ROUTER_FLUX_BACK' 'back'
ActionConst.BACK_ACTION string 'REACT_NATIVE_ROUTER_FLUX_BACK_ACTION' 'BackAction'
ActionConst.POP_AND_REPLACE string 'REACT_NATIVE_ROUTER_FLUX_POP_AND_REPLACE' 'popAndReplace'
ActionConst.POP_TO string 'REACT_NATIVE_ROUTER_FLUX_POP_TO' 'popTo'
ActionConst.REFRESH string 'REACT_NATIVE_ROUTER_FLUX_REFRESH' 'refresh'
ActionConst.RESET string 'REACT_NATIVE_ROUTER_FLUX_RESET' 'reset'
ActionConst.FOCUS string 'REACT_NATIVE_ROUTER_FLUX_FOCUS' 'focus'

ActionConst and Scene.type explaination

ActionConst

are just a bunch of constants represent real values of varIoUs actions/scene.type to avoid future changes. you can treat it like redux action.

ActionConst可以理解为就是一堆常量去表示真实的各种各样的actions/scene.type的值,这样做可以避免后期的变化。你可以像redux action一样处理它。

These can be used directly,Actions.pop() will dispatch correspond action written in the source code,or,you can set those constants in scene type,when you do Actions.main(),it will dispatch action according to your scene type or the default one.

ActionConst 也可以直接使用,例如:Action.pop()将分派给符合的action(你在代码中编写的action),或者,你可以在一个scene type中设置她们的常量。当你执行Action.main()时,它将根据你的scene type或者默认的一个去转发给合适的action。

Not every ActionConst can be used the same way ( use as an action or whether it can be set in scene type or not) that's why it's just a bunch of constants to mask the actual values.

不是每个ActionConst都可以使用相同的方式(作为一个动作使用,或者它是否可以在场景类型设置或不能),这就是为什么它只是一堆常量来掩盖实际的值。(我的理解是在转换为常量值的时候他会根据你定义的方式做分类,以此为依据进行处理,后续会阅读代码以确认~~)

Scene.type

Defines how the new screen is added to the navigator stack. One of push,modal,actionSheet,replace,switch,reset transitionToTop. Default is 'push'. And everyScene.typestring literal has a mapped constant in ActionConst,it is recommended to always use constant.

定义如何去增加一个新的屏幕到导航栈中。可以是push,actionSheet,replace,reset transitionToTop中的一个(相信前三个ios程序员将不会陌生,因为我现在主要是作为android程序员,但是也搞过ios开发,所有都懂那么一点点,理解起来好像挺有帮助的~~).默认的是push。每一个Scene.type都会在ActionConst中存在一个对应的常量,我们推荐总是使用常量来表示。

replace: tells navigator to replace current route with new route.

replace:告诉导航器使用一个新的route来替换当前的route。


actionSheet: shows Action Sheet popup,you must pass callback as callback function.

actionSheet:以弹出的方式展示一个Action Sheet,你必须传入一个回调作为回调方法


modal: type inserts its 'component' into route stack after navigator component. It could be used for popup alerts as well for varIoUs needed processes before any navigator transitions (like login auth process). it could be dismissed by using Actions.dismiss().

modal:在导航组件后的路由栈中插入该类型定义的组件。它可以被作为一个弹出的提示框使用,也可以在任何导航传输之前(像登录授权处理)做一些必须处理的操作进行使用。我们可以使用Actions.dismiss()关闭它。(类似android原生种的dialog,ios中的模态视图)。


switch: is used for tab screens.

switch:在tab 场景下使用。(一般是点击底部按钮切换不同的scene)。


reset: is similar toreplaceexcept it unmounts the componets in the navigator stack.

reset:类似replace,但是它在导航栈中卸载了该组件。


transitionToTop: will reset router stack ['route.name'] and with animation,if route has sceneConfig. eg

transitionToTop:如果路由有sceneConfig配置,如:,将根据name重置路由堆栈中的路由和动画。
