reactjs - 为什么我不能在 SunEditor 组件中直接使用 Props，它会显示以前的渲染数据？

Question

我在组件中传递道具并直接在 suneditor 中使用..

const SunEditorForRendering: React.FC<Props> = ({postContent }) => {
const [content, setContent] = useState("hello world");

    const editor = useRef<SunEditorCore>();
  // The sunEditor parameter will be set to the core suneditor instance when this function is called
  const getSunEditorInstance = (sunEditor: SunEditorCore) => {
    editor.current = sunEditor;
  };


 useEffect(() => {
    if (postContent) {
      editor.current?.core.setContents(postContent);
    }
  }, [postContent]);

         <SunEditor
          getSunEditorInstance={getSunEditorInstance}
          //setContents={content}
          setContents={postContent}
          onChange={handleOnChange}
       
        />
}
 

上面的代码无法按预期工作，并且编辑器的内容多次过时。但是，如果我不直接使用 postcontent 并首先将其保存在一个 state 中，然后将 state 设置为 editor ，它就可以正常工作。工作代码是

const SunEditorForRendering: React.FC<Props> = ({postContent }) => {
const [content, setContent] = useState("hello world");

    const editor = useRef<SunEditorCore>();
  // The sunEditor parameter will be set to the core suneditor instance when this function is called
  const getSunEditorInstance = (sunEditor: SunEditorCore) => {
    editor.current = sunEditor;
  };


 useEffect(() => {
    if (postContent) {
     setContent(postContent);//----> first save postcontent to new state
    }
  }, [postContent]);


useEffect(() => {
    if (content) {
      editor.current?.setContents(content)//---> here set content to editor
    }
  },[content]);

         <SunEditor
          getSunEditorInstance={getSunEditorInstance}
          setContents={content}
          onChange={handleOnChange}

        />
}

还有其他代码，但在上述两种情况下它们都是相同的
