描述
Description
CSS transform styles applied directly to <Text> components do not work consistently on iOS. The same code works correctly on Android.
In the example snippet below:
- Android: ✅ Text is translated as expected
- iOS: ❌ Text is not translated
<Text style={{ transform: [{ translateY: 50 }] }}>Transformed text</Text>
Occasionally a fast refresh will correct it but that's not consistent either.
Workaround
Wrapping the <Text> in a <View> and applying the transform to the <View> works on both platforms:
<View style={{ transform: [{ translateY: 50 }] }}>
<Text>Transformed text</Text>
</View>
Steps to reproduce
- Run the provided Expo Snack on an iOS device/sim

调研方向
首先在 iOS 设备或模拟器上运行必需的 Expo Snack 复现程序,并比较直接对 Text 应用的变换与使用 View 包裹的变通方案。调查报告中涉及的 Fabric/New Renderer 路径;完成的标准是,Text 上的直接 translateY 变换在 iOS 上能够像在 Android 上一样一致地应用。
