I am using
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
delegate to change the frame of my view based on the orientation type
i.e.,
if(UIInterfaceOrientationIsLandscape(interfaceOrientation))
{
self.view.frame=CGRectMake(0,0,500,300);
}
else
{
self.view.frame=CGRectMake(0,0,300,400);
}
How to handle the same situation in iOS 6 as
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
has been deprecated in iOS6.
I am using the following delegate to set all the orientations.
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationAllMask;
}
But,
-(BOOL)shouldAutoRotate
{
return YES;
}
is not getting invoked. How to handle this situation?
In the AppDelegate, I have added the ViewController Object to window as
[self.window addSubView:viewControllerObj]
The problem was with the above line. Orientation will work properly with the above line in iOS 5 but in iOS, for orientation to work properly, change the above line with
[self.window setRootViewController:viewControllerObj]
Then the app rotates when orientation changes.
Make sure the settings in the project and target allow for the orientations for each device type.
Also, the code you have in shouldAutorotateToInterfaceOrientation: you can put in viewDidLayoutSubviews.
Remember that in iOS 6 the handling of the rotation is take care in parents view. Less responsability to childs viewcontrollers. But more annoying for us that code everything without Interface builder.
Make sure all you orientation is enable.
Handling UINavigation orientation issue in iOS 6
1 Create a UINavigation+Rotation category class
2 put below methods in UINavigation+Rotation.m class
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject]supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
if ([self.viewControllers count] == 0) {
return UIInterfaceOrientationPortrait;
}
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
This method work fine for IOS 6 and Older versions

Use willAnimateRotationToInterfaceOrientation in iOS6.
