In my App, I have a tabbarController and 5 view controllers managed by it.
I only want one UIView rotate to landscape and make the tabbar invisible when rotate to landscape. In current condition, all my views autorotate themselves which is not what I expect.
The code of UIView which I dont want it rotate is:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if (UIInterfaceOrientationLandscapeLeft) {
// stop the rotation, keep it as portrait orientation
// from app document, it says for UITabbarController, rootview which is uitabbarcontroller and views managed by it should all agree on the same orientation otherwise they wont rotate.
// how can i do this?
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

I want to show one view controller in both orientation in iPhone. And when the screen is opening the preferred orientation should be portrait only. Then according to the device orientation it'll rotate. I found some solution and the screen is rotating too. But when I'm entering the screen it is auto rotating to landscape and than I've to manually rotate it to portrait.
Is there a simple solution to this problem?
You should implement preferredInterfaceOrientationForPresentation and
supportedInterfaceOrientations like:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIDeviceOrientationPortrait;
}
//You don't actually need to implement this as UIInterfaceOrientationMaskAllButUpsideDown is the default for iPhone
- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAllButUpsideDown;
}
I ma trying to lock screen orientation to only landscape orientation when a certain image is still visible, then when the image is hidden, unlock all orientations (targeting iOS 6):
-(BOOL)shouldAutorotate{
if (self.splashImageView.hidden == NO) {
return UIInterfaceOrientationMaskPortrait;//gets called when image is visible
}else{
return UIInterfaceOrientationMaskAll;//gets called when image is hidden
}
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
[self shouldAutorotate];
}
As you may notice, shouldAutorotate is called properly but the screen is always supporting landscape orientation even when the image is still visible, is there something missing?
P.S: Please note I am trying to get that to work on a tabbar view controller (a UIViewController subclass).
In your appdelegate you have those two methods.but do you have setting like in your project settings -> go to summary tab and see if orientation is set to only landscape or all.Just try to set those.
For our iPad application, I would like to allow for auto rotation of the screen in landscape mode (not portrait) to support both possible orientations. However, there are portions of our application during which the user needs shake and move the iPad into directions and orientations, that will trigger the auto rotation feature but should not.
is it possible to de- and re-activate the autoorientation, such that the orientation will be locked when entering this section of the app and unlocked when exiting?
if the specific section means another view controller, YES it is possible
just add this line of code to the controller ..
// which orientation that this view controller support
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
// prevent rotation
- (BOOL)shouldAutorotate
{
return NO;
}
// after present this view controller, which orientation do you prefer ?
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
I am having a problem with device orientation. I have an iPhone app that has some views, all of them should not rotate except one. So I take a look inside Info.plist; I select two device orientations, portrait and lanscape, and in the views I dont want to rotate so I put this.
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return NO;
}
but all the views rotate. Even with these lines in them. If change Info.plist to support no portrait. It works ok, just the view that I want to rotate, I put
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
And it does not work. I use iOS 6. Also tried
- (NSUInteger)supportedInterfaceOrientations
- (BOOL)shouldAutorotate
Try specifying exactly the orientations you would like the view to rotate to. For instance, if you want portrait only use this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
For rotating to all views, you can still use YES, although this will allow it to rotate to the upside down view which isn't always desired. To get both landscape orientations and right side up portrait, use this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
I'm wondering why iPad project based on UITabBarController won't autorotate when i specify some of the tab should autorotate in landscape mode and the other will autorotate in landscape and portrait mode.
i've used the
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
for all the UIViewController and specify if landscape return YES; other wise return NO;
In the other hand, if the UIViewController should rotate in landscape and portrait i've justreturn YES;` always.
Thx in advance.
for all the UIViewController you are loading in tabbarcontroller you must return True in
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
Note:
A tab bar controller will not auto rotate unless ALL the controllers it contains also auto rotate.

There is no easy way to have only one view in landscape mode, while the others are in landscape, nor an easy way to programmatically switch to landscape mode.
One possible approach would be using a CGAffineTransform to transform your view in your viewWillAppear (i.e., right before the view is shown):
- (void)viewWillAppear:(BOOL)animated; {
//-- Adjust the status bar
[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
//-- Rotate the view
CGAffineTransform toLandscape = CGAffineTransformMakeRotation(degreesToRadian(90));
toLandscape = CGAffineTransformTranslate(toLandscape, +90.0, +90.0 );
[self.view setTransform:toLandscape];
}
