Qunar React Native 组件

Radio 选择组件 >=v1.0.0

注意：这是一个受控组件，checked状态由React传进来，对它本身的操作并不会直接改变checked状态。
Radio
属性
hasBorder { React.PropTypes.bool }
是否为有border的形态
checked { React.PropTypes.bool }
选中状态
onPress { React.PropTypes.func }
点击回调，可从e.target.checked中获取当前选中状态
style { Text.propTypes.style }
组件样式，check/uncheck状态均生效
checkStyle { Text.propTypes.style }
组件样式，只在check状态生效
uncheckStyle { Text.propTypes.style }
组件样式，只在uncheck状态生效
