Coloring twice in OpenGl es

i m doing color picking for my project, i m working with iphone sdk and my project s开发者_运维问答ubstantially(for color picking part) load 3d models with texture, the "loader" own an array of objects, those objects are presented with drawView and are updated with redrawView. When i click with mouse on the iphone simulator i just call the method drwanWithOneUniqueColor that should color each object in the array with one different color. The result with number of models 3 so with array model count = 3 is: on the view just 1 object with 1 color , in a different position where was the object( in front of the view ) and under 3 models with texture and the 2 and 3 model are not colored why?

THE OBJECT VIEW and THE LOADER AND REDER OBJECTS http://pastebin.com/LHpmFAzn

i m working on and i m discovering that models was well colored but attached one on the other in this way i could see just 1 of them. now i should resolve the question of translate in the right way the objects.
