   Hi, another possibly dumb question:

   I want to display some configuration settings in a UITableViewController. I've tried using [[[UIApplication sharedApplication] keyWindow] addSubview:myConfigViewController.view]; which kinda works, but the table is very slow to respond and jerky, I guess because underneath it all my game is still running / processing.

   Is there a 'proper' way to handle this kind of thing? ( Ie, switching from the Cocos / OpenGL scene to a native cocoa style interface ( And back again! )

   Ta!

   run this command first: [[Director sharedDirector] pause];
   and when you return from the view run this: [[Director sharedDirector] resume];

   Hi, thanks, but this isn't working for me:

   My new view appears, but it's really unresponsive. I'm actually loading a view from a nib now rather than creating a UITableViewController derived object, but my setup is still pretty much the same:

   [[Director sharedDirector] pause];
   ConfigViewController *vw = [[ConfigViewController alloc] initWithNibName:@"Config" bundle:nil];
   [[[UIApplication sharedApplication] keyWindow] addSubView:vw.view];

   My view just has a UITableView dumped on it and is populated with some dummy data for now, scrolling it or selecting stuff is painfully slow.

   If I change the size of my view so that it's not quite screen sized, I can see the FPS counter from my cocos layer underneath, reading something like 3 fps.

   I guess I'm just missing something or just not getting how the cocos / UIKit stuff interact. Possibly the [[[UIApplication sharedApplication] keyWindow] addSubView:vw.view] is not the right way to do this - I've not fouind any examples that switch between cocos & UIKit views like this.

   Any ideas?

   First, those 3-4 fps you see are just fine, when you pause Director it continues to run at those tiny frames.

   Second, try adding your View to the Director's openGL View:
   

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

   Hi, thanks for the reply.

   I tried adding my view to the Directors openGL view as suggested, but the results are the same.

   I've started fiddling about a bit, and one of the things I'm doing at startup in my application delegate is turning the fast director on:

   [Director useFastDirector];

   I've found that if I comment this out ( ie, don't use the fast director ) then my UIKit stuff becomes responsive again.

   Could it be something in the fast director intefering with my view? I'm actually only using fast director 'cos it's in the 'best practices' - It could be that I've missed something that says fast director + UIKit is problematic.

   My app actually runs ok using the standard director so I'll probably just go with that for now, but i'd be interested in knowing if there is an issue with fast director!

   Cheers!
