Gestion de la mémoire dans iphone cocos2d

Question

Je développe une application ebook pour l'iPhone en utilisant cocos2d. J'utilise plus de 150 images (je suppose). Le problème est, tout en tournant d'une page à l'autre, les images se pendre au hasard ......

J'ai essayé cela aussi [[TextureMgr sharedTextureMgr] removeAllTextures]; mais en vain. Je suppose que le problème est avec la mémoire. Voici mon code pour toutes les pages:

-(id)init 
{ 
    if((self=[super init])) { 
     self.isTouchEnabled = YES; 
     [SimpleAudioEngine sharedEngine]; 
     NSLog(@"b4 cover"); 
     Sprite *bg1 = [Sprite spriteWithFile:@"a.jpg"]; 
     bg1.anchorPoint = CGPointZero; 
     [self addChild:bg1 z:-1]; 
     once = TRUE; 
     soundId = [[SimpleAudioEngine sharedEngine] playEffect:@".mp3"]; 
    } 
    return self; 
} 

-(void) transitionfront:(id) sender 
{ 
    [[SimpleAudioEngine sharedEngine] stopEffect:soundId]; 
    soundId1 = [[SimpleAudioEngine sharedEngine] playEffect:@"page_turn.mp3"]; 
    flip = [[Sprite spriteWithFile:@"a.jpg"] retain]; 
    [self addChild: flip z:1]; 
    [flip setPosition:ccp(160,240)]; 
    Animation* animation1 = [Animation animationWithName:@"Page1" delay:0.09]; 
    for(int i=1;i<4;i++) 
     [animation1 addFrameWithFilename: [NSString stringWithFormat:@".jpg", i]]; 

    id action = [Animate actionWithAnimation: animation1]; 
    //id action = [RepeatForever actionWithAction:[Animate actionWithAnimation: animation1]]; 
    [flip runAction:action]; 
    [NSTimer scheduledTimerWithTimeInterval:0.3 target:self selector:@selector(moveforward) userInfo:nil repeats:NO]; 
} 

-(void) moveforward 
{ 
    [[SimpleAudioEngine sharedEngine] stopEffect:soundId1]; 
    [[Director sharedDirector] replaceScene: [ [Scene node] addChild: [nextpage node] z:0] ]; 
} 

-(void) transitionback:(id) sender 
{ 
    [[SimpleAudioEngine sharedEngine] stopEffect:soundId]; 
    soundId1 = [[SimpleAudioEngine sharedEngine] playEffect:@".mp3"]; 

    flip = [[Sprite spriteWithFile:@".jpg"] retain]; 
    [self addChild: flip z:1]; 
    [flip setPosition:ccp(160,240)]; 
    Animation* animation1 = [Animation animationWithName:@"Page1" delay:0.09]; 
    for(int i=3;i>0;i--) 
     [animation1 addFrameWithFilename: [NSString stringWithFormat:@".jpg", i]]; 

    id action = [Animate actionWithAnimation: animation1]; 
    //id action = [RepeatForever actionWithAction:[Animate actionWithAnimation: animation1]]; 
    [flip runAction:action]; 
    [NSTimer scheduledTimerWithTimeInterval:0.3 target:self selector:@selector(movebackward) userInfo:nil repeats:NO]; 
} 

-(void) movebackward{ 
    //[[SimpleAudioEngine sharedEngine]stopEffect:@".mp3"]; 
    [[Director sharedDirector]replaceScene:[[Scene node]addChild:[b4page node] z:0]]; 
} 

-(void) glossary :(id) sender { 
    [[SimpleAudioEngine sharedEngine]stopEffect:soundId]; 
    [[Director sharedDirector]replaceScene:[[Scene node]addChild:[ node] z:0]]; 
} 

-(BOOL)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [touches anyObject]; 
    CGPoint cocosTouchPoint = [touch locationInView: [touch view]]; 
    CGPoint point = [[Director sharedDirector] convertToGL:cocosTouchPoint]; 

    NSLog(@"pointx: %f pointy:%f", point.x, point.y); 

    // Was a tab touched, if so, which one... 
    if (CGRectContainsPoint(CGRectMake(220, 0, 100, 70), point)) 
    { 
     if(once) 
     { 
      NSLog(@"enterred page1"); 

      [self transitionfront:nil]; 
      once = FALSE; 
     } 
    } 
    if (CGRectContainsPoint(CGRectMake(0,0,60,60), point)) 
    { 
     if(once) 
     { 
      NSLog(@"enterred cover"); 

      [self transitionback:nil]; 
      once = FALSE; 
     } 
    } 

    if (CGRectContainsPoint(CGRectMake(100, 15, 30, 30), point)) 
    { 
     if(once){ 
      [self glossary :nil]; 
      once = FALSE; 
     } 
    } 
    return kEventHandled; 
} 

-(void)playEffect:(NSString*)sound{ 
    if(effectPlayer!=nil){ 
     [effectPlayer release]; 
    } 
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:sound ofType:@"mp3"]]; 
    effectPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil]; 
    [effectPlayer setDelegate:self]; 

    [effectPlayer play]; 
} 

-(void)stopEffect 
{ 
    [effectPlayer stop]; 
} 

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

ne me pls aider ........ ne me donner une exacte de codage

c'est le err .....

Answer 1

Que voulez-vous dire par "allé vain"?

J'ai eu un problème similaire et lorsque vous choisissez d'enleverAllTextures vous perdez toutes les images que vous avez en mémoire et votre application ne trouve plus le fichier lié à CCSprites.

C'est parce que la méthode CCSprite initWithFile ajoute la texture à la sharedTextureCache:

-(id) initWithFile:(NSString*)filename 
{ 
    NSAssert(filename!=nil, @"Invalid filename for sprite"); 
    CCTexture2D *texture = [[CCTextureCache sharedTextureCache] addImage: filename]; 
    if(texture) { 
     CGRect rect = CGRectZero; 
     rect.size = texture.contentSize; 
     return [self initWithTexture:texture rect:rect]; 
    } 

    [self release]; 
    return nil; 
} 

également dans cette ligne vous manque "% i" pour désigner l'int lorsque craeting la chaîne avec le format:

[animation1 addFrameWithFilename: [NSString stringWithFormat:@"%i.jpg", i]]; 

aussi, vous utilisez l'animation, mais vous devez utiliser CCAnimation, par exemple:

CCAnimation* anim = [CCAnimation animationWithFrames:frames delay:0.1f]; 

Est-ce que cela aide?
