 * @component ToastState
 * @description
 *
 * ## 弹出层 / ToastState状态提示组件
 *
 * 相比于Toast只能传递文本, ToastState顾名思义, 他还能传递Toast状态, 这里支持的状态由四类:
 *
 * - success
 * - fail
 * - offline
 * - loading
 *
 * 其中, success, fail, offline为Icon提示, loading使用的Spinner组件进行提示, 并且可以根据props定义设置Spinner状态.
 *
 *```
 ToastState.present('Bottom was added successfully')
 *```
 *
 * #### 2. 传入Message和Duration
 *
 *```
 ToastState.present('Bottom was added successfully',1000)
 *```
 *
 * #### 3. 传入Options对象
 *
 *```
 ToastState.present({
    message: '只是文本',
    duration: 3000,
    dismissOnPageChange: true,
    onDismiss () {
      console.debug('2 onDismiss in promise success!')
    }
 })
 ToastState.present({
    message: '请稍后',
    duration: 3000,
    type: 'loading',
    spinner: {
      name:'ios'
    },
    cssClass: 'showCloseBtnToastCssClass',
    dismissOnPageChange: true,
    onDismiss () {
      console.debug('5 onDismiss in promise success!')
    }
 })
 ToastState.present({
    message: '请求成功',
    duration: 3000,
    type: 'success',
    cssClass: 'showCloseBtnToastCssClass',
    dismissOnPageChange: true,
    onDismiss () {
      console.debug('5 onDismiss in promise success!')
    }
 })
 *```
 *
 * #### 4. present方法
 *
 *```
 ToastState.present('Bottom was added successfully',1000)
 *```
 *
 * @props {String} message - Toast显示的message, 如果文本过程则折行并自动撑开容器
 * @props {Number} [duration=3000] - Toast开启时间, 过期后关闭
 * @props {String} [cssClass] - 额外的样式定义, 多个样式使用空格隔开
 * @props {Boolean} [dismissOnPageChange=false] - 当导航切换时, 是否自动关闭, 默认不关闭
 * @props {String} [onDismiss=noop] - 当关闭动画结束时执行的函数
 * @props {Object} [spinner] - Spinner组件的props对象
 * @props {String} [type=''] - toast 类型，展示相应图标，类型可选值： success, fail, offline, loading
 *
