iPhone开发之UITableView的小试牛刀 利用MVC模式从plist文件读取数据并字典转模型的格式实现

本文主要是介绍iPhone开发之UITableView的小试牛刀 利用MVC模式从plist文件读取数据并字典转模型的格式实现，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

 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：

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：
