   I am trying to switch my Sprites image/texture, when I call setTexture I get the following error.

   *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'CCSprite: setTexture doesn't work when the sprite is rendered using a CCSpriteBatchNode'

   How does one set the sprites image when using a batchNode?

   You should use setTextureRect instead. Use a spritesheet to keep track of the frames in an easy manner.

   
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: @"framesheet.plist"];
CCSpriteBatchNode bombBatch = [CCSpriteBatchNode batchNodeWithFile: @"framesheet.png" capacity:50];


   then you can change the sprite rect by:

   
[sprite setTextureRect: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: @"some_frame_you_defined_in_the_plist"].rect];

   If you want to change the texture, you'll have to change the texture for the entire SpriteBatchNode. All of the sprites using the SBN are referencing the same texture, so you can't just change one of them.

   You can do this:
   

   CCSpriteBatchNode *sbn = [CCSpriteBatchNode batchNodeWithFile:@"image1.png"];
   
   sbn.texture = [[CCTextureCache sharedTextureCache] addImage:@"image2.png"];

   Be careful when doing something like that though because a. I don't think it will play nicely with SpriteFrames or any active animations, and b. All of the sprites in the batch node will still be pointing to their previous texture rects. That is, a sprite with rect { 64,64,128,128 } from the first texture will show the same rect { 64,64,128,128 } in the new texture after you change.

   I just want to set the sprites png, no changing of the batch node, as the image I want to change it to is also in the same batch node.

   @fet_loa - Is this

   [sprite setTextureRect: [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: @"some_frame_you_defined_in_the_plist"].rect];

   The optimal way of doing it?

   Thanks

   There seems to be an issue that the image is set to the same rotation as the one in the texture atlas. Does the rotation need to be hard coded, or is there a way to get it to auto set?

   Actually just solved it. For anyone with the same issue here is the solution.

   CCSpriteFrame *frame = [[CCSpriteFrameCache sharedSpriteFrameCache]
   spriteFrameByName:@"yourImage.png"];

   [yourSprite setDisplayFrame:frame];
