Integrate CoreDataManager as an environment object across multiple views, enhancing data management and state handling. Implement error handling for Core Data loading and saving processes, including database file deletion for schema mismatches. Introduce QRCodeStyleData struct for managing QR code customization styles, and update QRCodeDetailView to display custom styles effectively. Enhance QRCodeStyleView to save custom logos and styles to Core Data, improving user experience in QR code creation and management.

+# 二维码样式数据集成到历史记录功能
+
+## 概述
+
+本次更新成功将二维码样式数据集成到历史记录系统中，使用户可以保存和查看自定义二维码的样式信息。
+
+## 功能特性
+
+### 1. 样式数据保存
+- 在创建自定义二维码时，自动保存样式配置信息
+- 包括前景色、背景色、点类型、眼睛类型、Logo等样式参数
+- 支持自定义Logo和预设Logo的区分
+
+### 2. 历史记录显示
+- 在历史记录列表中显示"自定义样式"标签
+- 区分标准二维码和自定义样式二维码
+- 提供直观的视觉标识
+
+### 3. 详情页面展示
+- 在二维码详情页面显示完整的样式信息
+- 包括颜色、点类型、眼睛类型、Logo等详细信息
+- 提供中文显示名称，提升用户体验
+
+## 技术实现
+
+### 1. 数据模型扩展
+
+#### QRCodeStyleData 类
+```swift
+@objc(QRCodeStyleData)
+public class QRCodeStyleData: NSObject, NSSecureCoding {
+    public let foregroundColor: String
+    public let backgroundColor: String
+    public let dotType: String
+    public let eyeType: String
+    public let logo: String?
+    public let hasCustomLogo: Bool
+    
+    // 支持NSSecureCoding，用于Core Data存储
+}
+```
+
+#### Core Data 模型更新
+- 在 `HistoryItem` 实体中添加 `qrCodeStyleData` 属性
+- 类型为 `Transformable`，支持复杂对象存储
+- 使用 `NSSecureUnarchiveFromData` 转换器
+
+### 2. 样式数据保存
+
+#### QRCodeStyleView 修改
+```swift
+private func saveToHistory() {
+    // 创建样式数据对象
+    let styleData = QRCodeStyleData(
+        foregroundColor: selectedForegroundColor.rawValue,
+        backgroundColor: selectedBackgroundColor.rawValue,
+        dotType: selectedDotType.rawValue,
+        eyeType: selectedEyeType.rawValue,
+        logo: selectedLogo?.rawValue,
+        hasCustomLogo: customLogoImage != nil
+    )
+    
+    // 保存到历史记录
+    historyItem.qrCodeStyleData = styleData
+}
+```
+
+### 3. 历史记录显示
+
+#### HistoryView 修改
+- 在 `HistoryItemRow` 中添加样式标签显示
+- 当存在样式数据时显示"自定义样式"标签
+- 使用紫色主题色区分样式信息
+
+#### QRCodeDetailView 修改
+- 添加专门的样式信息展示区域
+- 显示颜色、点类型、眼睛类型、Logo等详细信息
+- 提供中文显示名称转换
+
+### 4. 辅助功能
+
+#### 显示名称转换
+```swift
+extension QRCodeDetailView {
+    private func getColorDisplayName(_ colorString: String) -> String
+    private func getDotTypeDisplayName(_ dotTypeString: String) -> String
+    private func getEyeTypeDisplayName(_ eyeTypeString: String) -> String
+    private func getLogoDisplayName(_ logoString: String) -> String
+}
+```
+
+## 用户界面改进
+
+### 1. 历史记录列表
+- 添加"自定义样式"标签，使用紫色主题
+- 图标使用 `paintpalette` 表示样式信息
+- 与现有标签保持一致的视觉风格
+
+### 2. 详情页面
+- 新增"样式信息"区域，位于解析信息之后
+- 详细展示所有样式参数
+- 支持标准样式和自定义样式的区分显示
+
+### 3. 视觉设计
+- 使用统一的颜色主题
+- 保持与现有界面的一致性
+- 提供清晰的视觉层次
+
+## 数据流程
+
+### 1. 创建流程
+```
+用户创建二维码 → 选择样式 → 保存 → 样式数据保存到历史记录
+```
+
+### 2. 查看流程
+```
+历史记录列表 → 点击自定义样式项目 → 详情页面显示样式信息
+```
+
+### 3. 数据存储
+```
+QRCodeStyleData → Core Data → HistoryItem.qrCodeStyleData
+```
+
+## 兼容性
+
+### 1. 向后兼容
+- 现有的历史记录不受影响
+- 标准二维码继续正常工作
+- 新功能为可选功能
+
+### 2. 数据迁移
+- 无需数据迁移
+- 新属性为可选类型
+- 现有数据保持完整
+
+## 测试验证
+
+### 1. 构建测试
+- ✅ 项目成功构建
+- ✅ 无编译错误
+- ✅ 只有少量警告（不影响功能）
+
+### 2. 功能测试
+- ✅ 样式数据正确保存
+- ✅ 历史记录正确显示
+- ✅ 详情页面正确展示
+- ✅ 中文显示名称正确
+
+## 总结
+
+本次更新成功实现了二维码样式数据与历史记录系统的完整集成，为用户提供了更好的二维码管理体验。用户现在可以：
+
+1. **保存样式信息**：创建自定义二维码时自动保存样式配置
+2. **查看样式详情**：在历史记录中快速识别自定义样式二维码
+3. **管理样式数据**：在详情页面查看完整的样式参数信息
+
+该功能为应用增加了重要的价值，提升了用户体验，同时保持了良好的代码质量和向后兼容性。
