IOS GLKit Textures for Cube

Question

new to IOS OpenGL programming. I have worked through a few tutorials that talk about the basics of OpenGL ES and been able to create a small demo program that draws cubes in a scene at positions I want. Id like to apply a texture to the faces of the cube but for some reason this seems to be a near impossible task to figure out. Im using GLKit , Ive searched all over and can't find a dead simple tutorial on how to do this without a lot of other fluff. Can anyone point me in the correct direction or have a tutorial on this? It doesn't seem like this should be hard thing to do. I must be missing something..

Answer 1

Go here for many tutorials bout this http://www.raywenderlich.com/

or here

http://www.raywenderlich.com/5223/beginning-opengl-es-2-0-with-glkit-part-1

this one explains about textures in detail:

Id recomend not to use glkit directly (maybe some helper methods) since even tho it is easier as it works like opengl 1 most of the tutorials for gl es 2.0 wont use it and you will get confused.

Use this one for glkit to load textures

Try google with something like glkit texture example

this is what i got :

around line 119 you can see how to use the texture, i havent checked it but it seems valid. I usually prefer to just use normal opengl since even when you have a simple program the shader file is ridiculously simple, (like less than 10 lines).
