How to show UIButton over GLKView with UIViewController - IOS?

Question

I am new to OpenGL, I have been trying to show a button over the GLKView, but buttons are not showing. Here is what I have done...

context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES2];

    if (!_context) {
        NSLog(@"Failed to create ES context");
    }

    glview = [[GLKView alloc] initWithFrame:self.view.bounds];
    glview.context = _context;
    glview.delegate = (id)self;
    [self.view addSubview:glview];

Edit:

 [glview addSubview:call_btn];

I have created a UIViewController, added a GLKView as subview to self.view, everything working fine except the above problem (UIbuttons are not shown over the glkview). Any idea how to do it.

Where and how are you adding those buttons? Adding them as subviews to glView should work just fine. I hope you did set some background color or image to buttons as they are transparent by default and you just don't see them. — Matic Oblak, Apr 26 '13 at 09:04
Yeah I set background Image for buttons. Is that matters? What should I do now? — Newbee, Apr 26 '13 at 10:39

You'll have to add the buttons to the GLKView. If you add to self.view they are hidden because the GLKView is opaque and in front of them.
