通过目标C中的键从SwiftDeferredNSDictionary中提取值，其中键是Swift枚举

#import <Foundation/Foundation.h>

@interface ExtractValue : NSObject

+ (id)extractValueForKey:(NSString *)key fromDictionary:(NSDictionary *)dictionary;

@end

#import "ExtractValue.h"

@implementation ExtractValue

+ (id)extractValueForKey:(NSString *)key fromDictionary:(NSDictionary *)dictionary {
    return [dictionary valueForKey:key];
}

@end

import Foundation

enum MyEnum: String {
    case key1
    case key2
    // 添加其他枚举值...
}

func extractValue(from dictionary: NSDictionary, for key: MyEnum) -> Any? {
    let objcKey = key.rawValue as NSString
    return ExtractValue.extractValue(for: objcKey, from: dictionary)
}

// 示例用法
let dictionary: NSDictionary = ["key1": "value1", "key2": "value2"]
let value = extractValue(from: dictionary, for: .key1)
print(value) // 输出：Optional("value1")
