Question

Answer 1

With this above code of Brad Larson, you have to edit your EAGLView.m

- (id)initWithCoder:(NSCoder*)coder{
    self = [super initWithCoder:coder];
    if (self) {
        CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer;
        eaglLayer.opaque = TRUE;
        eaglLayer.drawableProperties = 
            [NSDictionary dictionaryWithObjectsAndKeys: 
                [NSNumber numberWithBool:YES],  kEAGLDrawablePropertyRetainedBacking, 
                kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil];
    }
    return self;
}

You have to change numberWithBool value YES
