Apologies if this is not on the right list.
I have an app with several views, one of which is an OpenGLES view
implemented by subclassing OpenGLES2DView.
When I switch from a normal view to the OpenGL view it draws the textured
sprite as expected, but when I switch from the OpenGL view back to the
previous UIKit view, and then back to the OpenGL view the screen is blank,
and all I see is the clear colour. The sprite is not drawing. The
coordinates for the sprite are the same each time. I can't work out why it
draws the first time round and not when I switch back to it the second
time.
On switching the OpenGL view and controller are both deallocated.
The most relevant code is here http://pastie.org/620291.
TIA
./Sven
