Button
一个简单的跨平台的按钮组件。可以进行一些简单的定制。
这个组件的样式是固定的。所以如果它的外观并不怎么搭配你的设计，那你需要使用TouchableOpacity或是TouchableNativeFeedback组件来定制自己所需要的按钮，或者你也可以在 github.com 网站上搜索 'react native button' 来看看社区其他人的作品。
import { Button } from 'react-native';
...
<Button
onPress={onPressLearnMore}
title="Learn More"
color="#841584"
accessibilityLabel="Learn more about this purple button"
/>
