How to add a UIView on top of an OpenGL game (iOS)

Question

I have downloaded this source from here: https://github.com/ericjohnson/canabalt-ios It is the source code of the Canabalt game for iOS

The game is built on the Flixel engine.

I wanted to achieve a simple thing. I want to add a UIView to one of the in-game screens. How can I achieve that?

I have tried doing stuff like:

UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 120)];
[myView setBackgroundColor:[UIColor redColor]];

[self add:myView];

This, of course, throws an error saying that: Incompatible pointer types sending 'UIView \*' to parameter of type 'FlxObject \*'

I cannot find any way to "convert" a UIView to FlxObject. It feels like a simple requirement, but the solution has eluded me so far. I have tried reading through this Flixel library to figure out some way to do this, but found nothing.

Any help guys?

You could try to add your view directly to the top window

[[[UIApplication sharedApplication] keyWindow] addSubview:myView];
