Unable to handle orientation in iOS 6? - ipad

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.

Answer 2

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.

Answer 3

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.

Answer 4

Make sure all you orientation is enable.

Answer 5

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];
UIWindow *_window = [[[UIApplication sharedApplication] delegate] window];
if ([PGPlatformUtils GetCurrentPlatform]==PGPlatformEnum_iPhone) {
switch (orientation) {
case 1:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.0];
[_window setTransform:CGAffineTransformMakeRotation (0)];
[_window setFrame:CGRectMake(0, 0, 320, 480)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:YES];
[UIView commitAnimations];
break;
case 2:

break;
case 3:

break;
default:
break;
}
}
else{
switch (orientation) {
case 1:

break;
case 3:

[_window setFrame:CGRectMake(0, 0, 768, 1024)];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:YES];
NSLog(#"*** 1 Orientation Call M_PI/2");
[UIView commitAnimations];
break;
case 4:

Use willAnimateRotationToInterfaceOrientation in iOS6.
