iOS 6 Orientation with Navigation Controller - objective-c

Question

I have an app that works fine on ios 5,im trying to upgrade my app to work on ios 6, i had read tons of questions and tutorials about using ios 6 orientation,
my problem is when i call my rootViewController its work fine with me, but when i push any viewController the orientation look so bad because i use the orientation to change the view sizes (my app support any orientation)
here is my code:
AppDelegate:
UINavigationController *nav =[ [UINavigationController alloc] initWithRootViewController:theView] ;
self.window.rootViewController = nav;
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window // iOS 6
{
return UIInterfaceOrientationMaskAll;
}
myFirstViewController:
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskAll;
}
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration{
[self viewWillAppear:NO];
}
-(BOOL)shouldAutorotate{
return YES;
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:NO];
if ( [[UIDevice currentDevice].systemVersion floatValue] >= 6.0){
if (pointRange.location != NSNotFound) {
UIInterfaceOrientation interfaceOrientation = [[UIDevice currentDevice] orientation];
if( (interfaceOrientation >= 3) ) {
width=1024;
self.view.frame=CGRectMake(0, 0, 1024, 768);
}
if ( (interfaceOrientation == 1) || (interfaceOrientation == 2 )) {
width=768;
self.view.frame=CGRectMake(0, 0, 768, 1024);
}}
....etc
and i did the same in my second view, Hope to find why!!

Answer 1

You could always make an extension to the UINavigationController like this
#implementation UINavigationController (RotationFix)
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate
{
return YES;
}
#end

even i suffered for 2 days.. gone through many tutorials, blogs, forums, even apple docs.
So far i came to know, In iOS 6 each template of the app should be handled in a different ways.
So far the discussions were only for view based app, and these changes were not working on navigation based app or tabBar based app.
Finally i got the solution, it like this
Implement a subclass of these two types UITabBarController or UINavigationController.
Got to know from this blog. Thanks to Shabbir for the solution.
