+# 应用名称更新总结
+
+## 更新内容
+将应用名称从 "MyQrCode" 更改为 "QR Code & Barcode Plus"
+
+## 修改的文件
+
+### 1. 本地化字符串文件 (Localizable.strings)
+更新了所有支持语言的 `app_title` 和 `app_name` 键值：
+
+**支持的语言**:
+- 🇺🇸 英语 (en.lproj)
+- 🇨🇳 简体中文 (zh-Hans.lproj)  
+- 🇩🇪 德语 (de.lproj)
+- 🇪🇸 西班牙语 (es.lproj)

+- 🇰🇷 韩语 (ko.lproj)
+- 🇵🇹 葡萄牙语 (pt.lproj)
+- 🇷🇺 俄语 (ru.lproj)
+- 🇹🇭 泰语 (th.lproj)
+
+**更新的键值**:
+```strings
+"app_title" = "QR Code & Barcode Plus";
+"app_name" = "QR Code & Barcode Plus";
+```
+
+### 2. InfoPlist.strings 文件
+更新了所有语言的 `CFBundleDisplayName` 和 `CFBundleName`：
+
+```strings
+"CFBundleDisplayName" = "QR Code & Barcode Plus";
+"CFBundleName" = "QR Code & Barcode Plus";
+```
+
+## 影响范围
+
+### ✅ 已更新的显示位置
+1. **启动界面** - 应用标题显示
+2. **系统设置** - 应用显示名称
+3. **应用商店** - 应用名称
+4. **所有本地化语言** - 11种语言支持
+
+### 📱 用户体验
+- 用户在主屏幕上看到的应用名称将显示为 "QR Code & Barcode Plus"
+- 启动界面中的应用标题将显示为 "QR Code & Barcode Plus"
+- 所有语言环境下都保持一致的名称显示
+
+## 技术细节
+
+### 本地化实现
+- 使用 `"app_title".localized` 在启动界面显示应用名称
+- 通过 `CFBundleDisplayName` 设置系统级应用显示名称
+- 支持动态语言切换，名称会根据用户语言设置自动更新
+
+### 构建状态
+- ✅ 项目构建成功
+- ✅ 无编译错误
+- ✅ 所有本地化文件已更新
+
+## 验证方法
+1. 运行应用，检查启动界面显示的应用名称
+2. 检查主屏幕上的应用图标名称
+3. 切换系统语言，验证多语言支持
+4. 检查设置中的应用信息显示
+
+## 完成时间
+2025年9月4日
+
+---
+**注意**: 应用名称更新已完成，所有相关文件都已同步更新，确保在不同语言环境下都能正确显示新的应用名称。
