it seems when i add a batchnode it crashes my app on my device but it runs fine on the simulator,

this is how i have it set up..

-(void) CharacterSpriteFrames {

    [[CCSpriteFrameCache sharedSpriteFrameCache]
     addSpriteFramesWithFile:@"ninja_run.plist"];
    NinjaSpriteBatchnode = [CCSpriteBatchNode batchNodeWithFile:@"ninja_run.png"]; 

    [[CCSpriteFrameCache sharedSpriteFrameCache]
     addSpriteFramesWithFile:@"ninjajump.plist"];
    NinjaSpriteBatchnode = [CCSpriteBatchNode batchNodeWithFile:@"ninjajump.png"];

}

self.listOfGameObjects = [CCArray array];
        [self CharacterSpriteFrames];

        ninja = [[Ninja alloc] initWithFile:@"proto01.png"];

        [ninja setPosition:ccp(150,190)];

        [[self listOfGameObjects] addObject:ninja]; 

        [self
         addChild:ninja
         z:1000
         tag:kNinjaSpriteTagValue];

does anybody have any idea why the app crashes on my device but not on the simulator?

i get no errors when i run it on my device it just crashes...

How big are the spritesheets? And what's the image format you're using. Did you receive any memory warnings when running on the device?

Which gen is your device? The largest size on 1g/2g devices is 1024x1024. More than that is likely to crash the app.

i am using a 4th generation iPod, my spritesheets are 2048x2048, and i did not receive any memory warning when running on the device

I would think the crash is something to do with going past the max texture size limitation for the device . To do a quick test on that, just bring your spritesheets down to 1024x1024 and see if it still crashes.

By the way, two 2048x2048 spritesheets will already eat up more than 32MB of texture memory, assuming you're using RGBA8888 format. And that's not including other sprites for UI elements and etc.

THIS IS THE OUTCOME OF A SERIES OF TEST..
this is going to be a long post but please bare with me.
i went and changed the size of the spritesheets to 1024x1024, and i still got a crash.

here is the crash log

i think i know what is causing the crash,
i have a background layer that uses texture transform to make the background look as if it were scrolling.
i have 3 textures using the texture transform.
i removed two of the textures and i replaced one of the textures with a random SMALLER image, i ran it and it did NOT crash.

the original texture using the texture transform are 512x480, that size applies to all three original textures.
if i remove two and use only one (original texture) using texture transform it crashes,
if i remove the texture Transform but add the textures as a child it does NOT crash.

this is how i apply Texture Transform to my texture

ttexture_ = [CCSprite spriteWithFile:@"FGround-hd.png"];

        ttexture_1 = [[CCTransformTexture alloc] initWithSprite:ttexture_];
        ttexture_.anchorPoint =ccp(0,0);
        ttexture_1.position = ccp( 0,0);

        ttexture_1.textureTransform->position =ccp(1.0f,0);

[self addChild: ttexture_1 ];

 CCFiniteTimeAction *action_1 = [CCRepeat actionWithAction:[CCTextureMoveBy actionWithDuration:2.0f position:ccp(1,0)] times:1];

        CCAction *action_2 = [CCTextureMoveTo actionWithDuration:0.f position:CGPointZero];

      CCAction*  action = [CCRepeatForever actionWithAction:[CCSequence actions:action_1,action_2,nil]];

        action.tag = kTextureAction;

        [ttexture_1 runAction:action];

now this is what has my mind boggling,
if i leave the texture's using texture transform alone and instead remove the Batchnode with my characters animation sprites, i get NO crash. But i also get no animations.
if i replace the batchnode to one using only 5 frames it still crashes..

what I'm guessing is that the device's ram is being overloaded and causing the crash.

So to make it short, using Texture Transform and using my batchnode at the same time causes a crash,

If i am correct how would i get my game to work with a scrolling background,Character,Enemy Characters, power Up, etc. all on the screen at once?

i know it is possible as i have seen it in other games?

I meant the real crash log. Look for "crash log ios" on google.

i looked for a crash log but i couldnt find one for my app on todays date.. i read somewhere that it might take awhile to appear.

anyways the app does not crash anymore!
and i didn't do anything to fix it, i just synced my iPod to my mac and there it does not crash!

I'm afraid the problem will return since i didn't find a official solution =/
