-# useResponsive 拆分迁移指南
-
-## 概述
-
-原有的 `useResponsive.ts` (485行) 已被拆分为多个专注的 hooks，以提高代码的可维护性和性能。
-
-## 新目录结构
-
-```

-├── useResponsive.ts         # 兼容层 (保持向后兼容)
-└── index.ts                 # 统一导出
-```
-
-## 新 Hook API 说明
-
-### useBreakpoint - 断点检测
-
-```typescript
-import { useBreakpoint, useFineBreakpoint } from '../presentation/hooks/responsive';
-
-// 基础断点: 'mobile' | 'tablet' | 'desktop' | 'wide'
-const breakpoint = useBreakpoint();
-
-// 细粒度断点: 'xs' | 'sm' | 'md' | 'lg' | 'xl' | '2xl' | '3xl' | '4xl'
-const fineBreakpoint = useFineBreakpoint();
-```
-
-### useScreenSize - 屏幕尺寸
-
-```typescript
-import { useScreenSize, useWindowDimensions } from '../presentation/hooks/responsive';
-
-// 完整屏幕尺寸信息
-const { 
-  width, height, 
-  breakpoint, fineBreakpoint,
-  isMobile, isTablet, isDesktop, isWide 
-} = useScreenSize();
-
-// 仅获取窗口尺寸
-const { width, height, scale, fontScale } = useWindowDimensions();
-```
-
-### useOrientation - 方向检测
-
-```typescript
-import { useOrientation } from '../presentation/hooks/responsive';
-
-const { orientation, isPortrait, isLandscape } = useOrientation();
-```
-
-### usePlatform - 平台检测
-
-```typescript
-import { usePlatform } from '../presentation/hooks/responsive';
-
-const { OS, isWeb, isIOS, isAndroid, isNative } = usePlatform();
-```
-
-### useResponsiveValue - 响应式值
-
-```typescript
-import { useResponsiveValue } from '../presentation/hooks/responsive';
-
-// 根据断点返回不同值
-const padding = useResponsiveValue({ xs: 8, md: 16, lg: 24 });
-
-// 响应式样式
-const style = useResponsiveStyle({
-  padding: { xs: 8, md: 16, lg: 24 },
-  fontSize: { xs: 14, lg: 16 }
-});
-```
-
-### useResponsiveSpacing - 响应式间距
-
-```typescript
-import { useResponsiveSpacing } from '../presentation/hooks/responsive';
-
-const gap = useResponsiveSpacing({ xs: 8, md: 16, lg: 24 });
-```
-
-### useColumnCount - 列数计算
-
-```typescript
-import { useColumnCount } from '../presentation/hooks/responsive';
-
-const columns = useColumnCount({ xs: 1, sm: 2, md: 3, lg: 4 });
-```
-
-### useBreakpointGTE / useBreakpointLT - 断点范围检查
-
-```typescript
-import { useBreakpointGTE, useBreakpointLT, useBreakpointBetween } from '../presentation/hooks/responsive';
-
-const isMediumUp = useBreakpointGTE('md');
-const isMobileOnly = useBreakpointLT('lg');
-const isTabletRange = useBreakpointBetween('md', 'lg');
-```
-
-### useMediaQuery - 媒体查询
-
-```typescript
-import { useMediaQuery } from '../presentation/hooks/responsive';
-
-const isMinWidth768 = useMediaQuery({ minWidth: 768 });
-const isPortrait = useMediaQuery({ orientation: 'portrait' });
-```
-
-## 迁移示例
-
-### 示例 1: 使用 useResponsive (旧)
-
-```typescript
-import { useResponsive, useResponsiveValue, useResponsiveSpacing } from '../hooks';
-
-function Component() {
-  const { width, isMobile, isTablet, isDesktop, isWide } = useResponsive();
-  const padding = useResponsiveSpacing({ xs: 8, md: 16 });
-  
-  return <View style={{ padding }} />;
-}
-```
-
-### 示例 2: 使用新专注 hooks (推荐)
-
-```typescript
-import { 
-  useScreenSize, 
-  useResponsiveSpacing 
-} from '../presentation/hooks/responsive';
-
-function Component() {
-  const { width, isMobile, isTablet, isDesktop, isWide } = useScreenSize();
-  const padding = useResponsiveSpacing({ xs: 8, md: 16 });
-  
-  return <View style={{ padding }} />;
-}
-```
-
-### 示例 3: 仅使用部分功能 (性能优化)
-
-```typescript
-import { useBreakpoint, usePlatform } from '../presentation/hooks/responsive';
-
-function Component() {
-  // 只订阅断点变化，不订阅尺寸变化
-  const breakpoint = useBreakpoint();
-  const { isIOS } = usePlatform(); // 平台不会变化，只计算一次
-  
-  return <View />;
-}
-```
-
-## 性能优势
-
-1. **按需订阅**: 只使用需要的功能，避免不必要的重渲染
-2. **细粒度更新**: 每个 hook 独立管理状态
-3. **平台常量**: usePlatform 返回常量，不会触发重渲染
-
-## 向后兼容
-
-原有的 `useResponsive` 仍然可用，但标记为 `@deprecated`：
-
-```typescript
-import { useResponsive } from '../hooks'; // 仍然可用
-
-function Component() {
-  const { width, height, isMobile, platform } = useResponsive(); // 仍然可用
-  return <View />;
-}
-```
-
-## 工具函数
-
-```typescript
-import { 
-  getBreakpoint, 
-  getFineBreakpoint,
-  isBreakpointGTE,
-  isBreakpointLT 
-} from '../presentation/hooks/responsive';
-
-// 非 hooks 版本，用于工具函数
-const breakpoint = getBreakpoint(800);
-const fineBreakpoint = getFineBreakpoint(800);
-const isGTE = isBreakpointGTE('md', 'sm');
-```
-
-## 类型导出
-
-```typescript
-import type { 
-  BreakpointKey,
-  FineBreakpointKey,
-  ResponsiveValue,
-  Orientation,
-  PlatformInfo,
-  ScreenSize,
-  MediaQueryOptions,
-  ResponsiveInfo, // 兼容层
-} from '../presentation/hooks/responsive';
-```
-
-## 常量
-
-```typescript
-import { BREAKPOINTS, FINE_BREAKPOINTS } from '../presentation/hooks/responsive';
-
-// BREAKPOINTS = { mobile: 0, tablet: 768, desktop: 1024, wide: 1440 }
-// FINE_BREAKPOINTS = { xs: 0, sm: 375, md: 414, lg: 768, xl: 1024, '2xl': 1280, '3xl': 1440, '4xl': 1920 }
