I'm confused between your two claims.
Above you say you have a view controller that displays a small view in the
center of the screen. Below you say that this is the view controller's view
(that is, the view assigned to the 'view' property).
There is a view (which fills the screen, let's call it basicView). When the
user taps the screen, the small view - the view controller's view (that is, the
view assigned to the 'view' property) - is shown in the middle of the screen.
And this small centered view does rotate, when the device is rotated.
The basicView does not rotate.
If you want a simple view in the center of the screen with a fixed size, then
the simplest way to do so is to make that view a subview of the view
controller's view. If you set the autoresizingMask correctly, then that view
won't be resized at all, and should maintain its position in its superview
(if nothing else ensuring the subview remains at the correct size and
position should be much easier than what it seems you are trying to do above).
The autoresizingMask contains only dashed lines.
The code in basicView (an UIView) is:
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
if ( self.sliderView == nil ) // load nib
{
NSBundle *mainBundle = [ NSBundle mainBundle ];
SliderViewController *tem = [ [ SliderViewController alloc ]
initWithNibName:@Sliders
bundle:
mainBundle
biGroup:
biGroup
cubeGlView:
self
];
self.sliderViewController = tem;
[ tem release ];
self.sliderView = self.sliderViewController.view;
self.sliderView.center = self.center;
[ self addSubview: self.sliderView ];
}
self.sliderView.hidden = NO;
}
Kind regards,
Gerriet.

As I alluded to earlier, if you are going to use view controller containment,
you MUST use the containment API if you want sane behavior. The reason you are
getting this behavior is that based on your greater conditions, the
SliderViewController you just created is getting rotation callbacks, and since
it doesn't have a parent view controller would assume it is a full screen view
controller and sizes itself for that.
I would recommend you either 1) adopt view controller containment and do this
addition in the view controller that owns basicView (which needs to be a
subclass to do this properly) of 2) make SliderViewController not a subclass of
UIViewController.

Since you don't have a view controller at all currently, then my recommendation would be to create a base view controller, install all of your controls into it at startup, and hide the ones that are on demand. This is far simpler than the approaches I outlined (which expected that you already had a view controller) and anything else you can do. (for all interested observers) Don't try to get away with not having a view controller (that is explicitly set as the window's rootViewController). Its simply not worth it. -- David Duncan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
