HarmonyOS 鸿蒙Next 如何在TurboModule中获取UIContext对象

我这边尝试过，是可以获取到的。并且能打开弹窗，我是在sampleApp的SampleTurboModule.ets的rnLog测试了。

rnLog(info:string)
{
  console.log("ReactNative.log: " + info)


  console.log("xxx", getContext(this).cacheDir)

  TextPickerDialog.show({
    range: ['apple1', 'orange2', 'peach3', 'grape4', 'banana5'],
    selected: 0,
    disappearTextStyle: { color: Color.Red, font: { size: 15, weight: FontWeight.Lighter } },
    textStyle: { color: Color.Black, font: { size: 20, weight: FontWeight.Normal } },
    selectedTextStyle: { color: Color.Blue, font: { size: 30, weight: FontWeight.Bolder } },
    onAccept: (value: TextPickerResult) => {
      // 设置select为按下确定按钮时候的选中项index，这样当弹窗再次弹出时显示选中的是上一次确定的选项
      //this.select = value.index
      //console.log(this.select + '')
      // 点击确定后，被选到的文本数据展示到页面
      //this.v = value.value as string
      console.info("TextPickerDialog:onAccept()" + JSON.stringify(value))
    },
    onCancel: () => {
      console.info("TextPickerDialog:onCancel()")
    },
    onChange: (value: TextPickerResult) => {
      console.info("TextPickerDialog:onChange()" + JSON.stringify(value))
    },
    onDidAppear: () => {
      console.info("TextPickerDialog:onDidAppear()")
    },
    onDidDisappear: () => {
      console.info("TextPickerDialog:onDidDisappear()")
    },
    onWillAppear: () => {
      console.info("TextPickerDialog:onWillAppear()")
    },
    onWillDisappear: () => {
      console.info("TextPickerDialog:onWillDisappear()")
    }
  })
}
