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?

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.

Only the top most Controller get's notified of the orientation change. If you add the controller as subview the message is not passed to this controller. – Dennis Stritzke Jun 06 '13 at 08:07

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.

I have also added that settings. Even then, orientation is not changing when I change the device orientation. Why? I have uploaded the info.plist file partial screen shot. Please see.. – Bharath Sep 20 '12 at 19:55

Your answer is partially correct. But, another mistake I made was that I added the viewController as subview to the window. Instead If I set that viewController object as `[self.window setRootViewController:viewControllerObj]` then orientation is working properly! – Bharath Sep 21 '12 at 10:52
Ah, good catch. There is a problem with view controllers and windows, where only the root view controller receives orientation change notifications. – Léo Natan Sep 21 '12 at 12:49

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.

Apple did a very bad job in iOS 6 for Orientation. We have to change all the apps to support iOS 6. (Why it's not supporting old way too ) – Bagusflyer Oct 10 '12 at 03:50
Totally agree. The worst that I changed everything to support iOS6, and removed the old methods, so when I tested in a old iPad after a while, nothing works. – lagos Oct 10 '12 at 07:49

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


-(BOOL)rotationChanged:(UIInterfaceOrientation)interfaceOrientation {
    NSInteger orientation = [[UIDevice currentDevice] orientation];

        switch (orientation) {
            case 1:
