iOS开发 东芝WifiSD卡 读取单反相机照片

因项目中需要读取东芝wifiSDcard中的图片，结合网上的资料 写出了一下Demo 做下记录

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

@interface VZWifiSDCardImage : NSObject
@property (nonatomic,copy) NSString *imagePath;        //图片地址
@property (nonatomic,copy) NSString *imageName;        //图片名称
@end


@interface VZWifiSDCardFolder : NSObject
@property (nonatomic,copy) NSString *folderName;        //文件名称
@property (nonatomic,strong) NSMutableArray<VZWifiSDCardImage *> *floderimages;        //文件夹下的图片
@end

@interface VZWifiSDCardImageManager : NSObject
//获取东芝WifiSDcard上面的图片内容
+(NSMutableArray<VZWifiSDCardFolder *> *)getImagesForWifiSDCard;
@end
