+# 多语言支持说明
+
+## 功能概述
+
+MyQrCode 应用现在支持多国语言，包括英文和中文，英文为默认语言。
+
+## 支持的语言
+
+- 🇺🇸 **English (en)** - 默认语言
+- 🇨🇳 **中文简体 (zh-Hans)**
+
+## 文件结构
+
+```
+MyQrCode/
+├── en.lproj/
+│   └── Localizable.strings          # 英文本地化字符串
+├── zh-Hans.lproj/
+│   └── Localizable.strings          # 中文本地化字符串
+├── LanguageManager.swift             # 语言管理器
+├── LanguageSettingsView.swift        # 语言设置界面
+├── ContentView.swift                 # 主界面（已本地化）
+├── ScannerView.swift                 # 扫描界面（已本地化）
+└── Info.plist                        # 语言配置
+```
+
+## 主要功能
+
+### 1. 语言切换
+- 在主界面右上角显示当前语言标识
+- 点击语言标识进入语言设置界面
+- 支持实时语言切换，无需重启应用
+
+### 2. 本地化内容
+- **应用标题**: MyQrCode
+- **主界面**: 条码扫描器 / Barcode Scanner
+- **扫描界面**: 扫描指令、按钮文本、提示信息
+- **扫描线样式**: 5种样式的本地化名称
+- **错误信息**: 扫描失败提示
+- **语言设置**: 设置界面的所有文本
+
+### 3. 语言管理
+- 自动保存用户语言选择
+- 应用启动时恢复上次选择的语言
+- 支持系统语言检测
+
+## 使用方法
+
+### 切换语言
+1. 在主界面点击右上角的语言标识
+2. 在语言设置界面选择目标语言
+3. 语言立即生效，无需重启
+
+### 添加新语言
+1. 创建新的 `.lproj` 文件夹（如 `ja.lproj`）
+2. 在 `Localizable.strings` 中添加翻译
+3. 在 `Language` 枚举中添加新语言
+4. 在 `Info.plist` 中添加语言代码
+
+## 技术实现
+
+### 语言管理器 (LanguageManager)
+- 单例模式管理语言状态
+- 使用 UserDefaults 持久化语言设置
+- 提供本地化字符串获取方法
+
+### 本地化扩展
+```swift
+extension String {
+    var localized: String {
+        return LanguageManager.shared.localizedString(for: self)
+    }
+}
+```
+
+### 通知系统
+- 语言变化时发送 `languageChanged` 通知
+- 界面自动响应语言变化
+
+## 本地化字符串示例
+
+### 英文 (en.lproj/Localizable.strings)
+```strings
+"main_title" = "Barcode Scanner";
+"scan_instruction" = "Place QR code or barcode in the frame";
+```
+
+### 中文 (zh-Hans.lproj/Localizable.strings)
+```strings
+"main_title" = "条码扫描器";
+"scan_instruction" = "将二维码或条形码放入框内";
+```
+
+## 注意事项
+
+1. **默认语言**: 英文为默认语言，确保所有字符串都有英文版本
+2. **字符串键**: 使用有意义的键名，便于维护
+3. **格式字符串**: 支持 `String(format:)` 的格式化字符串
+4. **实时更新**: 语言切换后界面立即更新
+5. **持久化**: 语言选择保存在 UserDefaults 中
+
+## 扩展建议
+
+- 添加更多语言支持（日语、韩语、法语等）
+- 支持系统语言自动检测
+- 添加语言特定的日期和数字格式
+- 支持 RTL 语言（阿拉伯语、希伯来语）
