新建一个具有simple  VIew的工程，并把相关图片拉进资源文件夹

在Supporting  files文件夹下新建work.plist文件，编辑内容如下图：

![Center][]

在工程下新建model文件夹，并在文件夹内新建model类Hero

根据文件的字典属性编辑Hero.h如下：

//
    //  Hero.h
    //  作业整理
    //
    //  Created by apple on 15/9/1.
    //  Copyright (c) 2015年 LiuXun. All rights reserved.
    //
    
    #import <Foundation/Foundation.h>
    
    @interface Hero : NSObject
    @property (nonatomic, strong) NSString * icon;
    @property (nonatomic, strong) NSString *iconName;
    @property (nonatomic, strong) NSString *title;
    @property (nonatomic, strong) NSString *title2;
    @property (nonatomic, strong) NSString *time;
    @property (nonatomic, strong) NSString *desc;
    @property (nonatomic, strong) NSString *imag1;
    @property (nonatomic, strong) NSString *imag2;
    @property (nonatomic, strong) NSString *imag3;
    @property (nonatomic, strong) NSString *goodLabel;
    @property (nonatomic, strong) NSString *shareLabel;
    
    -(instancetype) initWithDict:(NSDictionary *) dict;
    +(instancetype) heroWithDict:(NSDictionary *)dict;
    @end

编辑model类Hero.m如下：

//
    //  Hero.m
    //  作业整理
    //
    //  Created by apple on 15/9/1.
    //  Copyright (c) 2015年 LiuXun. All rights reserved.
    //
    
    #import "Hero.h"
    
    @implementation Hero
    -(instancetype) initWithDict:(NSDictionary *) dict
    {
        if (self = [super init]) {
    //        self.icon = dict[@"icon"];
    //        self.iconName = dict[@"ictonName"];
            [self setValuesForKeysWithDictionary:dict];
        }
        return self;
    }
    
    +(instancetype) heroWithDict:(NSDictionary *)dict
    {
        return [[self alloc] initWithDict:dict];
    }
    @end

在工程下新建VIews文件夹，并在内新建自定义单元格（继承自UITableViewCell类）

编辑HeroTableViewCell.h文件如下：

//
    //  HeroTableViewCell.h
    //  作业整理
    //
    //  Created by apple on 15/9/1.
    //  Copyright (c) 2015年 LiuXun. All rights reserved.
    //
    
    #import <UIKit/UIKit.h>
    
    #import "Hero.h"
    @interface HeroTableViewCell : UITableViewCell
    @property (nonatomic, strong) Hero *hero; //用来获取数据
    
    @property (nonatomic, strong) UIImageView *igvIcon;
    @property (nonatomic, strong) UILabel *lblIcon;
    @property (nonatomic, strong) UILabel *lblTitle;
    @property (nonatomic, strong) UILabel *lblTitle2;
    @property (nonatomic, strong) UILabel *lblDesc;
    @property (nonatomic, strong) UILabel *lblTime;
    @property (nonatomic, strong) UIImageView *imgv1;
    @property (nonatomic, strong) UIImageView *imgv2;
    @property (nonatomic, strong) UIImageView *imgv3;
    @property (nonatomic, strong) UILabel *lblGood;
    @property (nonatomic, strong) UILabel *lblShare;
    @property (nonatomic, strong) UIButton *btnGood;
    @property (nonatomic, strong) UIButton *btnShare;
    
    -(void)event:(UIButton *) senter;
    @end

编辑HeroTableView.m文件如下：

//
    //  HeroTableViewCell.m

    //
    //  Created by apple on 15/9/1.
    //  Copyright (c) 2015年 LiuXun. All rights reserved.
