数组按照日期分组.gif

/**字典的key*/
static NSString *DicKey = @"dateKey";
/**字典的value*/
static NSString *DicValue = @"dateArr";
/**tableView的section是否选中 @(1) 选中 @(0) 不选中*/
static NSString *SectionSelect = @"sectionSelect";

用到的model

.h文件

#import <Foundation/Foundation.h>
@interface CollectionWordModel : NSObject
/**单词id*/
@property (nonatomic, strong) NSString *wordId;
/**单词名称*/
@property (nonatomic, strong) NSString *name;
/**添加时间*/
@property (nonatomic, strong) NSString *createDate;
/**状态 normal(正常状态) selected(选中状态) unselected(非选中状态)*/
@property (nonatomic, strong) NSString *stateStr; // 自己定义的,类似点赞
@end

.m文件

#import "CollectionWordModel.h"
@implementation CollectionWordModel
@end

后台返回一组数据(一个数组), 然后按照日期进行分组, 用UIT

用到的model
