Switch
渲染布尔输入。
¥Renders a boolean input.
这是一个受控组件，需要 onValueChange 回调来更新 value 属性，以便组件反映用户操作。如果 value 属性未更新，组件将继续渲染提供的 value 属性，而不是任何用户操作的预期结果。
¥This is a controlled component that requires an onValueChange callback that updates the value prop in order for the component to reflect user actions. If the value prop is not updated, the component will continue to render the supplied value prop instead of the expected result of any user actions.
