Question

my problem is:
I’m making a game for iOS using cocos2d and this game has lots of levels, so I’ll have to create a loading scene to load my sprites for each level. ( like new backgrounds, monsters and other stuff )
But I have no idea about this, I’m adding all the Texture Packer Files (.plist and .pvr.ccz)
on the sharedSpriteFrameCache in the GameData.m.
Does anyone knows a good tutorial for this or can help me solve this?
Thanks!

So basically you want to know how to load and unload images as you see fit. How about

@implementation Level1

- (void) loadLevel
{
    CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
    CCTextureCache* textureCache = [CCTextureCache sharedTextureCache];

    // Add the sprite frames. This will load the texture as well
    [frameCache addSpriteFramesWithFile:@"monkey.plist"];
    [frameCache addSpriteFramesWithFile:@"player.plist"];
    [frameCache addSpriteFramesWithFile:@"enemy.plist"];

    // Load other textures that are going to be used
    _myBackgroundTexture = [textureCache addImage:@"background.png"];
}

- (void) unloadLevel
{
    CCSpriteFrameCache* frameCache = [CCSpriteFrameCache sharedSpriteFrameCache];
    CCTextureCache* textureCache = [CCTextureCache sharedTextureCache];

    // Remove textures
    [textureCache removeTexture:_myBackgroundTexture];

    // Remove sprite frames. This will load the texture as well
    [frameCache removeSpriteFramesFromFile:@"monkey.plist"];
    [frameCache removeSpriteFramesFromFile:@"player.plist"];
    [frameCache removeSpriteFramesFromFile:@"enemy.plist"];

    // Though normally, id use frameCache removeUnusedSpriteFrames and
    // textureCache removeUnusedTextures
}
