一、MVC
M：模型（一個類，處理資料源） V：視圖（View，進行排版） C：控制器（VC，将資料源指派給相應排版的地方）
1、單一視圖
1.1、MainModel.h —— M
#import <Foundation/Foundation.h>
//模型
//模型就是為了做屬性而存在的,就是為了存資料用的
@interface MainModel : NSObject
//屬性名要和字典的key一樣，不然賦不上值
@property(nonatomic,retain)NSString *pic;
@property(nonatomic,retain)NSString *name;
@property(nonatomic,retain)NSString *price;
@property(nonatomic,retain)NSString *author;
@property(nonatomic,retain)NSString *country;
@property(nonatomic,retain)NSString *info;
@property(nonatomic,retain)NSString *type;
-(id)initWithDic:(NSDictionary*)dic;//初始化方法
-(void)setValue:(id)value forUndefinedKey:(NSString *)key;//防崩
@end
1.2、MainModel.m —— M
#import "MainModel.h"
@implementation MainModel
-(void)dealloc
{
self.name = nil;
self.price = nil;
self.info = nil;
self.author = nil;
self.country = nil;
self.pic = nil;
self.type = nil;
[super dealloc];
}
-(id)initWithDic:(NSDictionary *)dic
{
self = [super init];
if(self)
{
[self setValuesForKeysWithDictionary:dic];//kvc給這個類的屬性指派
}
return self;
}
-(void)setValue:(id)value forUndefinedKey:(NSString *)key
{//實作就行，防崩
NSLog(@"%@",key);
}
@end
1.3、MainView.h —— V
#import <UIKit/UIKit.h>
//視圖，就是用來做UI的
//視圖裡應該做布局，然後有一些屬性，可以用來給布局上的東西指派（圖、字、對象、方法）
@interface MainView : UIView
@property(nonatomic,retain)UIImageView *pic;
@property(nonatomic,retain)UILabel *nameLab;
@property(nonatomic,retain)UILabel *pri;
@property(nonatomic,retain)UILabel *auth;
@property(nonatomic,retain)UILabel *info;
@property(nonatomic,retain)UILabel *type;
@property(nonatomic,retain)UILabel *country;
@property(nonatomic,retain)UIButton *btn;
@end
1.4、MainView.m —— V
#import "MainView.h"
@implementation MainView
-(void)dealloc
{
self.nameLab = nil;
self.pic = nil;
self.pri = nil;
self.auth = nil;
self.country = nil;
self.info = nil;
self.type = nil;
self.btn = nil;
[super dealloc];
}
-(id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if(self)
{
[self makeUI];
}
return self;
}
-(void)makeUI
{
self.pic = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 80, 120)];
[self addSubview:self.pic];
[self.pic release];
self.nameLab = [[UILabel alloc] initWithFrame:CGRectMake(100, 10, 210, 30)];
self.nameLab.font = [UIFont boldSystemFontOfSize:18];
[self addSubview:self.nameLab];
[self.nameLab release];
self.country = [[UILabel alloc] initWithFrame:CGRectMake(100, 40, 210, 20)];
[self addSubview:self.country];
[self.country release];
self.pri = [[UILabel alloc] initWithFrame:CGRectMake(100, 60, 210, 20)];
[self addSubview:self.pri];
[self.pri release];
self.auth = [[UILabel alloc] initWithFrame:CGRectMake(100, 80, 210, 20)];
[self addSubview:self.auth];
[self.auth release];
self.type = [[UILabel alloc] initWithFrame:CGRectMake(100, 100,210, 20)];
[self addSubview:self.type];
[self.type release];
self.info = [[UILabel alloc] initWithFrame:CGRectMake(10, 140, 300, 30)];
[self addSubview:self.info];
[self.info release];
self.btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.btn.frame = CGRectMake(10, 170, 300, 30);
self.btn.backgroundColor = [UIColor greenColor];
[self.btn setTitle:@"觀看" forState:UIControlStateNormal];
[self addSubview:self.btn];
}
@end
1.5、MainViewController.h —— C
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@end
1.6、MainViewController.m —— C
#import "ViewController.h"
#import "MainModel.h"
#import "MainView.h"
@interface ViewController ()
@property(nonatomic,retain)MainModel *model;
@property(nonatomic,retain)NSMutableArray *dataArr;
@end
@implementation ViewController
-(void)dealloc
{
self.dataArr = nil;
self.model = nil;
[super dealloc];
}
- (void)viewDidLoad {
[super viewDidLoad];
self.dataArr = [NSMutableArray arrayWithCapacity:0];
[self loadData];
[self makeUI];
}
-(void)loadData
{
NSArray *picArr = @[@"火影01.png",@"火影02.png"];

{
NSDictionary *dic = @{@"pic":picArr[i],@"name":nameArr[i],@"info":infoArr[i],@"price":priceArr[i],@"type":typeArr[i],@"country":countryArr[i],@"author":authorArr[i]};
//把字典的資料轉為存進模型對象中
MainModel *model = [[MainModel alloc] initWithDic:dic];
[self.dataArr addObject:model];//每次循環做一個model，然後把model存進數組
[model release];
//數組裡存着model
}
}
-(void)makeUI
{//隻要把做好的View貼過來就行了
for(int i = 0;i<self.dataArr.count;i++)
{
MainView *mainView = [[MainView alloc] initWithFrame:CGRectMake(0, 64+i*220, 320, 220)];
[self.view addSubview:mainView];
[mainView release];
//上面這樣，布局就完事了
MainModel *model = self.dataArr[i];
//下面用模型給V的屬性UI指派
mainView.pic.image = [UIImage imageNamed:model.pic];
mainView.nameLab.text = model.name;
mainView.pri.text = model.price;
mainView.info.text = model.info;
mainView.country.text = model.country;
mainView.auth.text = model.author;
mainView.type.text = model.type;
[mainView.btn addTarget:self action:@selector(btnDown) forControlEvents:UIControlEventTouchUpInside];
}
}
-(void)btnDown
{
NSLog(@"開始看火影");
}

}

2、Table使用MVC

二、MVC中的V的情況
1、一個V裡有一些UI，沒有類似的
2、循環V，多個類似的V —— 一個簡單的，tableView
3、一個V裡有一些類似的UI —— 詳情頁面
2.1、UpModel.h —— M
#import <Foundation/Foundation.h>
@interface UpModel : NSObject
@property(nonatomic,retain)NSArray *picNameArr;//存圖檔
@property(nonatomic,retain)NSArray *labelNameArr;//存圖檔下面字的
-(id)initWithDic:(NSDictionary*)dic;
-(void)setValue:(id)value forUndefinedKey:(NSString *)key;
@end
2.2、UpModel.m —— M
#import "UpModel.h"
@implementation UpModel
-(void)dealloc
{

{

}
return self;
}
-(void)setValue:(id)value forUndefinedKey:(NSString *)key
{
NSLog(@"%@",key);
}
@end
2.3、UpView.h —— V
#import <UIKit/UIKit.h>
@interface UpView : UIView
@end
2.4、UpView.m —— V
#import "UpView.h"

}
}
@end
2.5、MainViewController.h —— C
