Not able to set orientation in ipad app - iphone

Question

I'm using ios6 version for generating a new Ipad app. In my app i'm creating a split view. That split view has to always in a landscape mode. App is working in ipad 6.0 simulator. But not working in ipad 5.0 simulator. I want to run the app both ipad 6.0 and ipad 5.0.
I'm using this code
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL) shouldAutorotate {
return NO;
}

Answer 1

you can do in ios6 like this way:-
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
and check every time in ViewWillApear device Oriantation like:-
- (void)willRotateToOrientation:(UIInterfaceOrientation)newOrientation {
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
if (newOrientation == UIInterfaceOrientationLandscapeLeft || newOrientation == UIInterfaceOrientationLandscapeRight) {
//set your landscap View Frame
[self supportedInterfaceOrientations];
}
}
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
{
if(newOrientation == UIInterfaceOrientationPortrait || newOrientation == UIInterfaceOrientationPortraitUpsideDown){
//set your Potrait View Frame
[self supportedInterfaceOrientations];
}
}
// Handle rotation
}
-(void)viewWillAppear:(BOOL)animated
{
[self willRotateToOrientation:[[UIDevice currentDevice] orientation]];
[super viewWillAppear:YES];
}
UPDATE
likely people use checking deviceorientation like below way in putting this line in to ViewWillApear:-
[[UIApplication sharedApplication] statusBarOrientation];
[[UIDevice currentDevice] orientation];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(deviceRotated:) name:UIDeviceOrientationDidChangeNotification object:nil];
and
-(void)deviceRotated:(NSNotification*)notification
{
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
if(orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
{
//Do your stuff for landscap
}
else if(orientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
//Do your stuff for potrait
}
}
IN IOS5 only landscap you can do like bellow:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
return YES;
}
else
{
return NO;
}
}
if you wish to support all oriantation you need to just return YES like:-
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}

Answer 2

In iOS 5.0 you should use:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return interfaceOrientation == UIInterfaceOrientationMaskLandscape;
}
