cocos2d json解析iphone应用程序

Question

是否有任何良好的教程/源代码来解析jSon数据到cocos2d项目？我知道如何解析jSon（也是XML）到xcode中并显示到tableview中，但我需要为我的cocos2d项目执行此操作。 这是我要怎样做：

#import "Eighties.h" 
#import "HelloWorldLayer.h" 
#import "GameScene.h" 
#import "JSON.h" 
#define kLatestKivaLoansURL @"http://api.kivaws.org/v1/loans/search.json?status=fundraising" 
@implementation Eighties 
@synthesize responseData; 
+(CCScene *) scene 
{ 
    // 'scene' is an autorelease object. 
    CCScene *scene = [CCScene node]; 

    // 'layer' is an autorelease object. 
    Eighties *layer = [Eighties node]; 

    // add layer as a child to scene 
    [scene addChild: layer]; 

    // return the scene 
    return scene; 
} 


-(id) init 
{ 
// always call "super" init 
// Apple recommends to re-assign "self" with the "super's" return value 
if((self=[super init])) { 

    CGSize winSize = [[CCDirector sharedDirector] winSize]; 

    CCSprite *bg = [CCSprite spriteWithFile:@"bg.jpg"]; 
    [bg setPosition:ccp(winSize.width/2, winSize.height/2)]; 
    [self addChild:bg z:0]; 

    /* 
    CCMenuItem *menuItems = [CCMenuItemImage itemWithNormalImage:@"back_pink.png" selectedImage:@"back_blue.png" block:^(id sender) { 
     NSLog(@"Pressed"); 
     [[SimpleAudioEngine sharedEngine] playEffect:@"tongue-clap.wav"]; 
     [[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:1.0 scene:[GameScene scene] withColor:ccWHITE]]; 
    }]; 
    */ 


    CCMenuItem *menuItems2 = [CCMenuItemImage itemWithNormalImage:@"back_pink.png" selectedImage:@"back_blue.png" target:self selector:@selector(loadData)]; 

    menuItems2.position = ccp(winSize.width/2-50, winSize.height/2-50); 

    CCMenu *menu = [CCMenu menuWithItems:menuItems2, nil]; 
    menu.position = ccp(winSize.width/2, winSize.height/2); 
    [self addChild:menu]; 





} 
return self; 
} 

-(void)test { 
NSLog(@"Success"); 
UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"Success" 
                message:@"Test Method Called" 
               delegate:nil 
             cancelButtonTitle:@"OK" 
             otherButtonTitles:nil]; 
[message show]; 
} 

-(void)loadData 
{ 
self.responseData = [NSMutableData data]; 

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:kLatestKivaLoansURL]]; 
[[NSURLConnection alloc] initWithRequest:request delegate:self]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 
[responseData setLength:0]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
[responseData appendData:data]; 
} 

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { 
[connection release]; 
self.responseData = nil; 
} 

#pragma mark - 
#pragma mark Process loan data 
- (void)connectionDidFinishLoading:(NSURLConnection *)connection { 
[connection release]; 

NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
self.responseData = nil; 

NSArray* latestLoans = [(NSDictionary*)[responseString JSONValue] objectForKey:@"loans"]; 
[responseString release]; 

//choose a random loan 
for (int i=0; i<=18; i++) { 
    NSDictionary* loan = [latestLoans objectAtIndex:i]; 

    //fetch the data 
    NSNumber* fundedAmount = [loan objectForKey:@"funded_amount"]; 
    NSNumber* loanAmount = [loan objectForKey:@"loan_amount"]; 
    //float outstandingAmount = [loanAmount floatValue] - [fundedAmount floatValue]; 

    //NSString* name = [loan objectForKey:@"name"]; 
    //NSString* country = [(NSDictionary*)[loan objectForKey:@"location"] objectForKey:@"country"]; 

    //set the text to the label 
    /* 
    label.text = [NSString stringWithFormat:@"Latest loan: %@ from %@ needs another $%.2f, please help", 
        name,country,outstandingAmount 
        ]; 
    */ 

    NSLog(@"%d",i); 
    //NSLog(@"%@",label.text); 
    NSLog(@"\n"); 
    /* 
    UIAlertView *message = [[UIAlertView alloc] initWithTitle:name 
                 message:country 
                delegate:nil 
              cancelButtonTitle:@"OK" 
              otherButtonTitles:nil]; 
    [message show]; 
    */ 
}

Answer 1

有很多的方法来反序列化JSON对象，某些方面甚至烤成SDK。

这question详细几种方法可以解决这个问题。

，或者你可以把你的JSON，并有该实用程序生成的解析代码为您 https://itunes.apple.com/us/app/json-accelerator/id511324989?mt=12
