我如何將以下代碼類轉換為函陣列件-有解無憂

在這里，我從我的商店檔案夾中匯入了一些其他檔案，此螢屏用于 pin 身份驗證。

在這里，我上傳了我需要在類組件中轉換為函陣列件的整個代碼，對于整個代碼，我是 react-native 的新手，請指導我并幫助我，在此先感謝

為了將類組件轉換為功能性組件，您需要分離類和道具行為，而是使用“鉤子”。

我會給你一些例子，而不是手動改變你的整個解決方案；

PinAuthentication = (props) => {

const [passcode, setPasscode] = useState('')

const showToast = () => Toast.show('Please enter a valid pin', Toast.LONG)

return (
    <Observer>
    {() => (
        <>
            <FastImage ... />
            ...
        </>
    )}
  )
}

因此，如果您想繼續使用狀態，請使用 UseState。使用“function”或“const”完全宣告您的方法。并洗掉的所有實體this，只需使用范圍變數名稱。

uj5u.com熱心網友回復：

查看功能組件檔案。

無論您在何處使用this.state，都想將其轉換為React.useState.
您不需要渲染，因為您只需要回傳一個可渲染物件（jsx null// React.Fragment）。
您的函式幾乎已經存在，只需添加const和參考它們而不帶this前綴。

然后，您將完成 90% 的作業。
