ipad - Unable to handle orientation in iOS 6?

Question

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?

Answer 1

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.
