First UIView in Portrait orientation and second in Landscape - iphone

Question

I have an app which has 2 view controllers. The first viewcontroller should be in portrait and it's ok, but when I'm loading the second view controller, I could not make the app orientation to be landscape... The problem is with iOS 6.
I have tried everything I found on SO.
Using [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO]; on viewWillAppear and viewDidLoad,
and also:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (interfaceOrientation == UIInterfaceOrientationPortrait) {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
} else {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
}
-(BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
-(NSInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscapeRight;
}

Answer 1

Add these code in 2nd View Controller's viewDidLoad method to transform view into landscape :
[self rotateController:self degrees:-90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];
//set it according to 3.5 and 4.0 inch screen in landscape mode
[self.view setBounds:CGRectMake(0, 0, 480, 320)];
add rotateController method :
-(void) rotateController:(UIViewController *)controller degrees:(NSInteger)aDgrees
{
UIScreen *screen = [UIScreen mainScreen];
if(aDgrees>0)
controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.height, screen.bounds.size.width);
else
{
controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.width, screen.bounds.size.height);
}
controller.view.transform = CGAffineTransformConcat(controller.view.transform, CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(aDgrees)));
}
Now in viewWillDisappear's method to transform view into protrait . Add these:
[self rotateController:self degrees:90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
//set it according to 3.5 and 4.0 inch screen in protrait mode
[self.view setBounds:CGRectMake(0, 0, 320, 480)];
Also your orientation methods should be like these if not added add these :
- (BOOL)shouldAutorotate
{
//make view landscape on start
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeLeft;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
EDIT : Add these macro for radian
#define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)

Answer 2

you may add this code on this view controller where you want to fix your orientation
Code as Below
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
return UIInterfaceOrientationMaskPortrait;
}
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
return (toInterfaceOrientation==UIInterfaceOrientationPortrait);
}
}
and second view controller you may want to rotate all orientation then not necessary to adding any code ios6 will manage the orientation automatically.

Answer 3

You need to select the landscape mode in application summary-> deployment info.
Also if you are using xib file to design the UI, you need to set the orientation of second view controller to landscape

Answer 4

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
-(BOOL)shouldAutorotate
{
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
-(NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
You were not returning the NO in the method shouldAutorotate , replace you existing code with this .
Hope it will help you.

Answer 5

Prior to iOS 6 i.e in iOS 5 and earlier, an app and a view controller’s rotation is controlled by the individual viewcontrollers while in iOS 6 and later, the view controllers responsible for rotation are the container Viewcontrollers such as UINavigationController & UITabBarController . What are you using as the rootviewcontroller in your project??
Autorotation is clearly explained here in this post- Autorotation in iOS
