Try Your code on actual device hope you dont get this problem…
OpenGL ES. OpenGL ES uses renderers on devices that are slightly different from those it uses in iPhone Simulator. For this reason, a scene on the simulator and the same scene on a device may not be identical at the pixel level. See “Drawing with OpenGL ES” in iPhone Application Programming Guide for details.”
