greetings,

to add a couple of UITextFields to my cc2d layer, i'm constructing the uikit object manually, and ultimately adding it via:

[[[Director sharedDirector]openGLView]addSubview:submitText];

when i do a replace view on the director to switch to my next scene, all UI objects stay behind.

i know you can do a removeFromSuperview, but you would normally call that on a uiview instance.

is there anyway to remove an individual UI item after it's been added as a subview?

thanks!

I add with:
[tvc.view setTag:kTweetView];
[[[UIApplication sharedApplication] keyWindow] addSubview:tvc.view];

and remove with:
[[[[UIApplication sharedApplication] keyWindow] viewWithTag:kTweetView] removeFromSuperview];

yeah, but you're adding an entire view -- i'm just adding a ui component (i.e. button or textfield)...

so i guess i can try to overlay the layer with a view... and remove the entire view as i replace the layer.

i shouldn't have to do this, though... surely there are games out there that would benefit from segmented controllers, activity indicators, textfields, textviews.

do these components NEED to be in a uiview for them to be cleared/removed when done with?

i guess i was just approaching it the wrong way.

removeFromSuperview does work... i just need to get a proper reference to each of the components. so in my dealloc:

NSArray * subviews = [[Director sharedDirector]openGLView].subviews;
for (id sv in subviews) {
[((UIView *)sv) removeFromSuperview];
[sv release];
}

this cleaned them up properly.
