mvc应用到cocos2d的简单理解

mvc顾名思义model,view,controller

controller包含model,view

-------------controller.h--------------

#import <Foundation/Foundation.h>
#import "cocos2d.h"
#import "mvcModel.h"
#import "mvcView.h"

@interface mvcController : NSObject <CCTouchOneByOneDelegate>
{
mvcModel *mymodel;
mvcView *myview;
}
@property (nonatomic, retain) mvcModel *mymodel;
@property (nonatomic, retain) mvcView *myview;
@end

-------------controller.m--------------

#import "mvcController.h"

@implementation mvcController
@synthesize mymodel,myview;


-(id) init {
if (self=[super init])
{
// 一个数据模型对应一个view，如果多个模型就对应多个view，在controller中增加array保存对它们的管理
self.mymodel = [[[mvcModel alloc]init] autorelease];
self.myview = [[[mvcView alloc]init] autorelease];

// 实现CCTouchOneByOneDelegate接口，使得controller获取touch事件
[[[CCDirector sharedDirector] touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
}
return self;
}

// touch事件方法
- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {

static int x = 1;

// 修改model中的title属性,view会自动修改
self.mymodel.title = [NSString stringWithFormat:@"第%d下",x];
self.mymodel.mypos = CGPointMake(100+x, 100);

// 调用方法使model的改变通过view显示
[self.mymodel didChange:self.myview];

x++;
return YES;
}


- (void)dealloc
{
[[[CCDirector sharedDirector] touchDispatcher] removeDelegate:self];
[mymodel release];
[myview release];
[super dealloc];
}
@end

-------------model.h--------------

#import <Foundation/Foundation.h>

// 接口部分
@class mvcModel;
@protocol ModelDelegate <NSObject>

@required
-(void)modelDidChange:(mvcModel *)model;
@end


@interface mvcModel : NSObject
{
NSMutableSet *delegates;
NSString *title;
CGPoint mypos;
}
@property (nonatomic, retain) NSString *title;
@property (nonatomic) CGPoint mypos;

-(void)didChange:(id<ModelDelegate>)delegate;

@end

-------------model.m--------------

#import "mvcModel.h"

@implementation mvcModel
@synthesize title,mypos;

-(id)init {
if (self=[super init]) {
delegates = [NSMutableSet new];
}
return self;
}

// 调用接口中的方法，既调用了实现接口的view中方法
-(void)didChange:(id<ModelDelegate>)delegate
{
[delegate modelDidChange:self];
}


- (void)dealloc
{
[title release];
[super dealloc];
}

@end

--------------view.h---------------

#import "cocos2d.h"
#import "mvcModel.h"

// 实现model接口
@interface mvcView : CCLabelTTF<ModelDelegate>

@end

--------------view.m--------------

#import "mvcView.h"
#import "mvcController.h"

@implementation mvcView

-(id) init {
if (self=[super initWithString:@"mvc模式" fontName:@"Marker Felt" fontSize:32])
{
self.anchorPoint = ccp(0.5, 0.5);
self.position = ccp(320/2, 480/2);
}
return self;
}

// model改变调用接口方法更改view显示
-(void)modelDidChange:(mvcModel *)model
{
self.string = model.title;
self.position = model.mypos;
}

@end

总结controller完成了和用户的交互部分,

controller修改了自己包含的model,

model改变后通过协议更改了controller中的view展示给用户
