In iOS 6, shouldAutorotateToInterfaceOrientation
is not working, but it worked fine in iOS 5.0 and 5.1.
What do I need to change for iOS 6? Here is my code:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if([[[SampleApplicationAppDelegate instance].callInfoDictionary valueForKey:IS_CHAT] isEqualToString:NO_RESPONSE])
{
int nAngle = 0;
BOOL bRet = NO;
switch (interfaceOrientation) {
case UIInterfaceOrientationPortrait:
nAngle = 90;
bRet = YES;
NSLog(@".......Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
NSLog(@"Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
break;
case UIInterfaceOrientationPortraitUpsideDown:
nAngle = 270;
bRet = YES;
_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
break;
case UIInterfaceOrientationLandscapeLeft:
nAngle = 0;
bRet = YES;
//_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
break;
case UIInterfaceOrientationLandscapeRight:
nAngle = 180;
bRet = YES;
//_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
break;
default:
break;
}
return bRet;
}
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
return YES;
return NO;
}
When I searched for this orientation problem, all I found was this and this, but nothing worked for me :(
Please help .....
EDIT: This is happening because Apple has changed the way of managing the Orientation of UIViewController
. In iOS6 orientation handles differently. In iOS6 shouldAutorotateToInterfaceOrientation
method is deprecated. View controllers (such as UINavigationController
) do not consult their children to determine whether they should autorotate. By default, an app and a view controller’s supported interface orientations are set to UIInterfaceOrientationMaskAll
for the iPad idiom and UIInterfaceOrientationMaskAllButUpsideDown
for the iPhone idiom.
If you want a specific view to be changed to the desired orientation you have to do some sort of subclass or category and override the autorotation methods to return the desired orientation.
Place this code in your root view controller. This will help the UIViewController
to determine its orientation.
//RotationIn_IOS6 is a Category for overriding the default orientation.
@implementation UINavigationController (RotationIn_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
@end
Now you need to implement below methods (introduced in iOS6) in viewController for orientation
- (BOOL)shouldAutorotate
{
//returns true if want to allow orientation change
return TRUE;
}
- (NSUInteger)supportedInterfaceOrientations
{
//decide number of origination tob supported by Viewcontroller.
return UIInterfaceOrientationMaskAll;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
//from here you Should try to Preferred orientation for ViewController
}
And put your code inside the below method. Whenever device orientation is changed this method will be called:
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation duration:(NSTimeInterval)duration
{
if([[[SampleApplicationAppDelegate instance].callInfoDictionary valueForKey:IS_CHAT] isEqualToString:NO_RESPONSE])
{
int nAngle = 0;
BOOL bRet = NO;
switch (interfaceOrientation) {
case UIInterfaceOrientationPortrait:
nAngle = 90;
bRet = YES;
NSLog(@".......Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
NSLog(@"Preview = %f %f",_previewCamera.frame.size.width,_previewCamera.frame.size.height);
break;
case UIInterfaceOrientationPortraitUpsideDown:
nAngle = 270;
bRet = YES;
_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
break;
case UIInterfaceOrientationLandscapeLeft:
nAngle = 0;
bRet = YES;
//_previewCamera.transform = CGAffineTransformMakeRotation(M_PI*1.5);
break;
case UIInterfaceOrientationLandscapeRight:
nAngle = 180;
bRet = YES;
//_previewCamera.transform = CGAffineTransformMakeRotation(M_PI_2);
break;
default:
break;
}
}
Edit: check your window, you need to add the controller on window as rootViewController
rather than addSubview
like below
self.window.rootViewController=viewController;

I hope this was helpful.
