TypeScript 和 React Native：RN 样式的类型定义是否错误？

Question

我认为在 React 中允许将数组分配给样式？

像这样：

import React from 'react';
import { Text } from "react-native";

// ...

render() {
  const textStyles = [styles.text];
  return <Text style={textStyles}>Some Text</Text>;
}

但 TSLint 抱怨这一行：

[ts]
Type 'RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }>[]' is not assignable to type 'StyleProp<TextStyle>'.
  Type 'RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }>[]' is not assignable to type 'RecursiveArray<false | TextStyle | RegisteredStyle<TextStyle> | null | undefined>'.
Types of property 'pop' are incompatible.
  Type '() => RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }> | undefined' is not assignable to type '() => StyleProp<TextStyle>'.
    Type 'RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }> | undefined' is not assignable to type 'StyleProp<TextStyle>'.
      Type 'RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }> | undefined' is not assignable to type 'StyleProp<TextStyle>'.
      Type 'RegisteredStyle<{ color: string; fontWeight: string; fontSize?: undefined; padding: number; textAlign: "center"; } | { color: string; fontSize: number; fontWeight?: undefined; padding: number; textAlign: "center"; }>' is not assignable to type 'StyleProp<TextStyle>'.

这里发生了什么？React Native的类型是不是错了？或者我是否应该以某种方式将这些数组类型转换为 RN 样式？

您可以测试一些方法来解决您的问题，希望这有效：

1：style={styles.yourStyle as any}也许你应该采取行动！

2：我看不到你如何实现你的样式，但你可以测试这样的东西吗？

import { StyleSheet, TextStyle, ViewStyle } from "react-native";

type Style = {
    container: ViewStyle;
    title: TextStyle;
    icon: ImageStyle;
};

export default StyleSheet.create<Style>({
    container: {
        flex: 1
    },
    title: {
        color: red
    },
    icon: {
        width: 10,
        height: 10
    }
});
