Memory management in iphone cocos2d
- by muthu
i am iphone developer very new to this field....i am developing a ebook app in iphone using cocos2d...i use more than 150 images(i guess) the problem while turning from one page to another images get hanged randomly......
i tried this also [[TextureMgr sharedTextureMgr] removeAllTextures]; but went in vain...i guess the the problem is with the memory.....this my coding for all the 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] ];
}

}
-(BOOL)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

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)
{

}
}

}
}
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];
}
do pls help me........ do give me a exact coding
