android的bean与iOS的model对比理解

简单粗暴的理解(类比学习大法)：android的bean等价于iOS的model。类中定义了属性，后续通过类取出属性中的值。

------------------------------------------android------------------------------------------

在bean类中定义属性

StoreFocusBean.java

package com.mzy.one.bean;
public class StoreFocusBean {
    private StoreBean store;
    public StoreBean getStore() {
        return store;
    }
    public static class StoreBean {
        private Integer state;
        public Integer getState() {
           return state;
        }
    }
    
}

数据源获取并使用bean类

MineCollectActivity.java

import com.mzy.one.utils.GsonUtil;
import com.mzy.one.bean.StoreFocusBean;
public class MineCollectActivity extends AppCompatActivity implements View.OnClickListener {
  public List<StoreFocusBean> mList = new ArrayList<>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_mine_collect);
        // 省略部分代码    
        JSONArray jsonArray = jsonObject.optJSONArray("data");// jsonObject是接口获取到的列表数据
        mList = GsonUtil.jsonToList(jsonArray.toString(), StoreFocusBean.class);
         if (mList.get(position).getStore() != null) {
          .....
        }
}

在model类中定义属性

ZBStoreTypeModel.h

#import <Foundation/Foundation.h>

NS_ASSUME_NONNULL_BEGIN

@interface ZBStoreTypeModel : FYBaseModel
@property(nonatomic,strong) NSString *categoryId;
@property(nonatomic,strong) NSString *state;
// 分类名
@property(nonatomic,strong) NSString *name;
@property(nonatomic,assign)NSInteger select;
@end

NS_ASSUME_NONNULL_END

ZBStoreTypeModel.m

#import "ZBStoreTypeModel.h"
@implementation ZBStoreTypeModel
+ (NSDictionary *)modelCustomPropertyMapper {
    // 将personId映射到key为id的数据字段
    return @{@"categoryId":@"id"};
}
@end

数据源获取并使用model类 (1)

#import "ZB_BenefitingPeopleVCViewController.h"
#import "ZBStoreTypeModel.h"
#import "ZB_BenefitCategoryCell.h"
@interface ZB_BenefitingPeopleVCViewController ()<UITableViewDelegate,UITableViewDataSource>
@property (nonatomic,strong) NSMutableArray<ZBStoreTypeModel *> *storTypeDataArray;
@property (nonatomic,strong)NSString  *categoryID;// 分类id
@end

@implementation ZB_BenefitingPeopleVCViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // 省略部分代码
    NSArray *temp = [NSArray yy_modelArrayWithClass:ZBStoreTypeModel.class json:responseObject[@"data"]];
    [self.storTypeDataArray addObjectsFromArray:temp];
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
  // 省略部分代码
   ZBStoreTypeModel *model = self.storTypeDataArray[indexPath.section];
   model.select = 1;
   self.categoryID = model.categoryId;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
  ZB_BenefitCategoryCell *cell = [tableView dequeueReusableCellWithIdentifier:ZB_BenefitCategoryCellID];
        if (cell == nil) {
            cell = [[ZB_BenefitCategoryCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:ZB_BenefitCategoryCellID];
        }
        // 执行(2)中的setModel方法
        cell.model = self.storTypeDataArray[indexPath.section];
        return cell;
}

@end

(2)

ZB_BenefitCategoryCell.h

#import <UIKit/UIKit.h>
#import "ZBStoreTypeModel.h"
NS_ASSUME_NONNULL_BEGIN

@interface ZB_BenefitCategoryCell : UITableViewCell
 
@property(nonatomic,strong)ZBStoreTypeModel *model;
@end

NS_ASSUME_NONNULL_END

ZB_BenefitCategoryCell.m

#import "ZB_BenefitCategoryCell.h"

@interface ZB_BenefitCategoryCell()
@property(nonatomic,strong)UILabel *nameLabel;
@end
@implementation ZB_BenefitCategoryCell
// 部分代码已省略
-(void)setModel:(ZBStoreTypeModel *)model{
    _model = model;
     if(model.select == 1){
           self.nameLabel.textColor = [UIColor redColor];
       }else{
           self.nameLabel.textColor = [UIColor colorWithHexString:@"333333"];
       }
    self.nameLabel.text = model.name;
}


@end
