How to add CCTexture2D to CCTextureCache cocos2d

Question

I have some encrypted images.. They are pretty heavy, so I want to preload them by adding them to CCTextureCache. However CCTextureCache does not accept CCTexture2D as a parameter.. What can I do?

CCTexture2D *img = [[[CCTexture2D alloc] initWithImage:[UIImage imageWithContentsOfEncryptedFile:path]] autorelease];

        [[CCTextureCache sharedTextureCache] addImage:img]; // not accepted!!

Two options:

add a method to cache CCTexture2D* objects with a key (unique string)
save the UIImage to disk (in Application Support directory), then load it as normal with cocos2d

The latter option will cause a notable delay due to the save & load process. I'd recommend the first approach. Most of the code you need to write that function is already in CCTextureCache, I believe there may even be just the method you need that only needs to be made public in the interface.

understood well.. Thanks.. I was also wondering how I can check if an image has already been added to the cache? – user123 Mar 15 '13 at 00:25
call textureForKey: if it returns nil this texture isn't cached – CodeSmile Mar 15 '13 at 08:35
