How to delete textures in OpenGL 2.x?

Question

I followed this tutorial to create a basic game using OpenGL and after profiling it, discovered that even after a sprite is removed, the textures are not being released creating a memory leak. I easily fixed the problem by creating a cache in the Sprite class, but I would like to know how I can delete the texture itself for future reference. It is loaded with GLKTextureLoader.

Answer 1

GLuint index = self.textureInfo.name;
glDeleteTextures(1, &index);
