描述

在旧架构中,我们可以使用command option +/-实时更改字体缩放。在新架构中,需要手动按R键刷新以应用新的字体缩放。

重现步骤

  1. gh repo clone yzhe554/new-arch-font-scale
  2. cd new-arch-font-scale
  3. npm i

嘿,@cortinico,这个问题还有一个副作用。我是react-native-unistyles的作者,Unistyles会在不同的事件(如字体缩放变化)上自动重新渲染视图。在新架构中,行为不同,文本会显示在边缘被截断。它最初不可见,因为用户需要像上面提到的那样重置应用程序,但在使用Unistyles时,第一次重新渲染后就可见了。
这是unistyles问题的链接:jpudysz/react-native-unistyles#256
复现方法:就像上面通过@yzhe554链接的一样
最小步骤:

export default function App() {
    const [counter, setCounter] = useState(0)
    
    return (
        <View 
            style={{
              flex: 1,
              backgroundColor: '#fff',
              alignItems: 'center',
              justifyContent: 'center',
            }}
        >
          <Text style={{fontSize: 24}}>RN 24 Label Testing!!!</Text>
          <Text style={{fontSize: 18}}>RN  18 Label Testing!!!</Text>
          <Text style={{fontSize: 16}}>RN 16 Label Testing!!!</Text>
          <Button onPress={() => setCounter(prevState => prevState + 1)} title="Re-render" />
          <StatusBar style="auto" />
        </View>
    )
}

尝试更改字体缩放并然后按重新渲染按钮。
