Objective C - app works in simulator and on other iPhones, but won't run on my own iPhone 4

Question

My app works fine in the simulator, and on other devices. I have an iPhone 4 with the latest iOS update, and the app refuses to run on my device.

It seems to be a problem surrounding retina-display images. The error spew I get when attempting to run on the phone is:

The odd thing is that the images it is puking on are in the app.

Again, the app works on other devices and in the simulator. Here is the code that loads the images:

backgroundNode = [CCParallaxNode node];
[self addChild:_backgroundNode z:-1];

_backgroundGrid1 = [CCSprite spriteWithFile:@"grid.png"];
_backgroundCircuits1 = [CCSprite spriteWithFile:@"bg-circuits.png"];

_backgroundGrid1.anchorPoint = CGPointMake(0,0);
_backgroundCircuits1.anchorPoint = CGPointMake(0,0);
CGPoint gridSpeed = ccp(0.05, 0.05);
CGPoint circuitSpeed = ccp(0.1, 0.1);

[_backgroundNode addChild:_backgroundGrid1 z:1 parallaxRatio:gridSpeed positionOffset:ccp(0,-winSize.height)];
[_backgroundNode addChild:_backgroundCircuits1 z:0 parallaxRatio:circuitSpeed positionOffset:ccp(0,-winSize.height)];

I've deleted the app from my phone, run a "clean," restarted Xcode, and restarted my computer. Still no luck. I've also re-provisioned my phone. I've also deleted and re-added the assets to the project.

To be honest, it does say within your log file that the image size of 1024 x 4096 is far greater than the supported 2048 x 2048:

You say it runs on other devices but what devices are they? If they are not retina enabled, I imagine the respective image size would be 512x2048 thus fitting the 2048x2048 maximum size.

If your retina-display images are beyond those dimensions, it simply will not work - the 2048x2048 should already encompass the retina-sized images. You may need to revise your game to use smaller dimensions.

Answer 2

You should really look into cutting down your images into smaller chunks and possibly placing them in a sprite sheet for performance. Then you can simply add the images slices next to each other using something like this

    for (int i = 0; i < amountOfSprites; i++){
        CCSprite *sprite = [CCSprite spriteWithSpriteFrameName:spriteName];
        sprite.anchorPoint = ccp(0,0);

        sprite.position = ccp((i * sprite.contentSize.width),0);


        [yourBatchNode addChild:sprite];
    }
