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

 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：

在当前工程下新建controllers文件夹用来存放跳转的控制器：
