Steps to reproduce
  1. Add a parent container with transparent border color, border radius and overflow: hidden set
      <View
        style={{
          margin: 150,
          borderWidth: 4,
          borderColor: 'transparent',
          borderRadius: 16,
          overflow: 'hidden',
          height: 80,
          width: 60,
        }}>
        <View
          style={{
            width: '100%',
            height: '100%',
            backgroundColor: 'red',
          }}></View>
      </View>
  1. On iOS, the child view is not clipped by the parent container.

调研方向

首先,在使用 React Native 0.72.5 的 iOS 上运行链接的 Snack,并将透明边框的情况与截图进行比较。跟踪 iOS 视图的裁剪和 border-radius 的行为;完成的标准是,即使边框颜色为透明,子元素也会按照圆角父元素进行裁剪。
