> [DatePickerIOS](http://facebook.github.io/react-native/docs/datepickerios.html#content) ## DatePickerIOS 日期选择控件 ## 属性 | 名称 | 类型 | 意义 | 默认值 | | --- | --- | --- | --- | | date | Date | 当前选择的日期基础 | 无默认值,必须显式设置 | | minimumDate | Date | 选择范围的最小值 | 无 | | maximumDate | Date | 选择范围的最大值 | 无 | | minuteInterval | enum | 分钟选择的间隔in(1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30) | 1 | | mode | enum | 选择器的模式(‘date’, ‘time’, ‘datetime’) | datetime | | timeZoneOffsetInMinutes | number | 时区偏移量,以分钟为标准 | 采用设备的时区 | ## 函数 * onDateChange :时间改变时调用 ## 默认显示 ## 源码 ~~~ 'use strict'; var React = require('react-native'); var { DatePickerIOS, AppRegistry, StyleSheet, View, } = React; var helloworld = React.createClass({ render: function() { return ( <DatePickerIOS date = { new Date()} /> ); } }); var styles = StyleSheet.create({ }); AppRegistry.registerComponent('hellowrold',() => helloworld); ~~~ ## 默认样式 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f018dfc.jpg) ## 属性的使用 ## mode ### time ~~~ <DatePickerIOS date = { new Date()} mode="time" /> ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f02e4b6.jpg) ### datetime ~~~ <DatePickerIOS date = { new Date()} mode="datetime" /> ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f042ad2.jpg) ### date ~~~ <DatePickerIOS date = { new Date()} mode="date" /> ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f055a50.jpg) ## minuteInterval 这个属性只能在分钟出现的选择器中才会起作用,当`mode="date"`是不起作用的。 ### mode=”time” ~~~ <DatePickerIOS date = { new Date()} mode="time" minuteInterval={3} /> ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f06f8e6.jpg) ### mode=”datetime” ~~~ <DatePickerIOS date = { new Date()} mode="datetime" minuteInterval={3} /> ~~~ ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f08a5d3.jpg) ## onDateChange 选择时间时,该属性设置的函数会被调用 ~~~ onDateChange: function(date) { console.log('doctorq'); this.setState({date: date}); }, ...... <DatePickerIOS date = { new Date()} mode="datetime" onDateChange={this.onDateChange} /> ~~~ 选择时间后,控制台打印信息如下: ~~~ 2015-09-01 19:21:57.391 [info][tid:com.facebook.React.JavaScript] 'doctorq' 2015-09-01 19:22:00.575 [info][tid:com.facebook.React.JavaScript] 'doctorq' 2015-09-01 19:22:04.141 [info][tid:com.facebook.React.JavaScript] 'doctorq' ~~~ ## timeZoneOffsetInMinutes ~~~ <DatePickerIOS date = { new Date()} mode="time" timeZoneOffsetInMinutes={(-2) * (new Date()).getTimezoneOffset()} /> ~~~ 我现在的时间是北京时间下午7点31.如果我们用上面的代码,就会变成上午3点31,时区的定义我们不讨论,我们只是看`timeZoneOffsetInMinutes`改变的效果: ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-07_568e13f0a0181.jpg)
