1、模型定义

@interface DailyThemesViewModel : NSObject

@property (strong,nonatomic) NSMutableArray *stories;
@property (strong,nonatomic) NSString *imageURLStr;
@property (strong,nonatomic) NSString *name;
@property (strong,nonatomic) NSArray *editors;

- (void)getDailyThemesDataWithThemeID:(NSNumber *)themeID;

@end

2、更新数据

- (void)getDailyThemesDataWithThemeID:(NSNumber *)themeID {

    [HttpOperation getRequestWithURL:[NSString stringWithFormat:@"theme/%@",themeID] parameters:nil success:^(id responseObject) {
        NSDictionary *jsonDic = (NSDictionary *)responseObject;
        NSArray *storiesArr = jsonDic[@"stories"];
        NSMutableArray* tempArr = [NSMutableArray array];
        for (NSDictionary *dic in storiesArr) {
            StoryModel *model = [[StoryModel alloc] initWithDictionary:dic];
            [tempArr addObject:model];
        }
        [self setValue:tempArr forKey:@"stories"];
        [self setValue:jsonDic[@"background"] forKey:@"imageURLStr"];
        [self setValue:jsonDic[@"name"] forKey:@"name"];
        [self setValue:jsonDic[@"editors"] forKey:@"editors"];
    } failure:nil];
}
