 <p>In your app delegate, look for this line:</p> <pre><code>EAGLView *glView = [EAGLView viewWithFrame:[window bounds] pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8 depthFormat:0 // GL_DEPTH_COMPONENT16_OES ]; </code></pre> <p>or search for </p> <pre><code>EAGLView *glView </code></pre> <p>and you will find it..</p>
