Orientation support in sdk 3.0

Question

Hi,
In my app, I use the following code to pop up another view controller:
[self presentModalViewController:myController animated:YES];
User may pop this controller from portrait or landscape mode. But once it is shown, I do not want it to rotate. So in MyController class, I have
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return NO;
But when I run my app, it gave the following warning:
2009-09-29 18:10:24.734 Jog[667:20b] The view controller <JogBackgroundInfoController: 0x133a370> returned NO from _shouldAutorotateToInterfaceOrientation: for all interface orientations. It should support at least one orientation.
I did not see this message in SDK 2.X. Does anyone know how to fix it?
Thanks,
ff

I would think that it would be as simple as reading the current device orientation
at the time the view is initiated, and then return YES only for that orientation.
So, obtain the current orientation, just before you open the modal view, and in the
modal view's shouldAutoRotateToInterfaceOrientation, return YES for that saved value.
See UIApplication Class Reference
{quote}statusBarOrientation
The current orientation of the application’s status bar.
@property(nonatomic) UIInterfaceOrientation statusBarOrientation
{quote}
and UIViewController Class Reference
{quote}
shouldAutorotateToInterfaceOrientation:
Returns a Boolean value indicating whether the view controller autorotates its view.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceO rientation
{quote}
In my current app, I force everything to landscape right....
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
I have the impression that you are trying to simply block rotation altogether while in that view.
I would check the docs to see if there is a property that inhibits rotation or auto rotation.
I know you can block autoresizing on rotation, but am not sure if there's a simpler way,
since you want to allow rotation, but just not re-rotating while in that view.
