MJExtension 模型转换

起因

来了新公司,看看上一手的代码,如果上一手,有使用过类似的工具就不会导致现在呢么多坑.

快速引用

#import "MJExtension.h" 

MJCodingImplementation

+ (NSDictionary *)replacedKeyFromPropertyName{
    return @{@"hashString":@"hash"};
}

+ (NSDictionary *)mj_objectClassInArray{
    return @{
             @"newsList":[TTVHomeChannelNewsModelNewsList class],
             @"headlineList":[TTVHomeChannelNewsModelNewsList class],
             };
}

测试程序

        NSString *UserId = [NSString stringWithFormat:@"%ldAAAAAAATTTTTTTT.data", [PKUserInfoTool userInfo].uid];
        NSString *PKPostLablePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:UserId];
        NSMutableArray *ary = [NSMutableArray array];
        for (int i = 0; i < 10; i++) {
            [ary addObject:[NSArray arrayWithObjects:[NSString stringWithFormat:@"label%d",i],@"123",@"456", nil]];
        }
        PKLog(@"pring in ram%@", ary);
        
        PKLabelSelectionModel *data = [[PKLabelSelectionModel alloc] init];
        data.ids = ary;
        
        //写入数组
        [[NSFileManager defaultManager] removeItemAtPath:PKPostLablePath error:nil];
        [NSKeyedArchiver archiveRootObject:data toFile:PKPostLablePath];
        
        //读取数组
        PKLabelSelectionModel *read  = [NSKeyedUnarchiver unarchiveObjectWithFile:PKPostLablePath];
        PKLog(@"read from local:%@", read.ids);

PKLabelSelectionModel.c

#import "PKLabelSelectionModel.h"
#import "MJExtension.h"

@implementation PKLabelSelectionModel

PKLabelSelectionModel.h

#import <Foundation/Foundation.h>

@interface PKLabelSelectionModel : NSObject

//名字
@property (nonatomic, strong) NSMutableArray* names;
//id
@property (nonatomic, strong) NSMutableArray* ids;

建立模型

程序模型

#import <Foundation/Foundation.h>

@interface PKQuestionDate : NSObject

// isOpen	int	是否开启问答(0代表不开启，1代表开启）
@property (nonatomic, assign) int isOpen;

//开启每轮问题的时间，例：'20:25'（isOpen为0时不填此参数）
@property (nonatomic, assign) NSString  *startTime;

//问答开启的星期数，例：0,0,1,0,1,0,1，表示星期三、五、日，触发新一轮（isOpen为0时不填此参数）
@property (nonatomic) NSMutableArray *qaDay;

//一轮可回答的问题条数（isOpen为0时不填此参数）
@property (nonatomic, assign)int questionCount;

//是否开启有新提问时通知我（isOpen为0时不填此参数）
@property (nonatomic, assign)int isNoticeMe;

@end

字典模型

转换数据使用

PKQuestionDate *data = [PKQuestionDate mj_objectWithKeyValues:dict[@"data"]];
self.openFlag = data.isOpen;
