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 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 know may be it's a duplicate question, but I tried many answers described here and I can't get it working from hours.
I'm working on an application for IOS 6 and IOS 7, just I need to move from my first viewController "A" which is on Landscape orientation, to a second viewController "B" which is on Portrait orientation.
I configured the project to enable all desired orientation, set the "appropriate" code, but still get the second view displayed vertically on a landscape orientation..
here is the code I set for first controller :
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape ;
}
Plz help.
If you use the UINavigationViewController methods(pushViewController:animated: and popViewControllerAnimated:), the views will inherit the previous view's orientation.
On the other hand, if you use presentModalViewController:animated: and dismissModalViewControllerAnimated: methods, everything works perfectly.
Also here is a sample project which is also changing orientation as required by you
my app has been working fine until I've tried making some changes using the ios 6 SDK
The app runs in portrait mode 99% of the time. This has been constrained by only allowing portait mode to be available in the info.plist
There is one view controller which needs to be shown in landscape mode. This is achieved "manually" by simply rotating the view by 90 degrees, like so:
self.view.transform = CGAffineTransformMakeRotation(3.14159/2);
This still works fine in iOS 6.
However, this view controller has some text fields. When the user taps one it shows the keyboard. Since I've only rotated the view (and not actually changed the orientation of the device), the keyboard comes out in portrait mode, which is no good.
In previous versions of iOS, I set the orientation of the status bar to be landscape, and as a byproduct, this would set the keyboard to be landscape as well, like this:
[[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationLandscapeRight animated:NO];
However, this has stopped working for iOS 6.
I have read a million stack overflows trying to get this to work, but still have no luck.
Changing the keyboard orientation and transform is an difficult part and not a good solution(especially when it changes status bar orientations).
Better solutions is to allow application to support all orientations.
Implement the Orientation delegates inside your ViewControllers asper the rotation support.
For Supporting only Landscape
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return interfaceOrientation == UIInterfaceOrientationLandscapeLeft
|| interfaceOrientation == UIInterfaceOrientationLandscapeRight ;
}
- (BOOL)shouldAutorotate
{
return NO;
}
For Supporting only Portrait
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
I have created a project, with both portrait and landscape orientation. What should I do to keep only a few screens rotatable?
Play with:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
If you have a UITabBarController, then you you will have problems, because either all rotate or none. Although I think there are some workarounds.
I want to make a landscape iPad app.
I did below 3 things. the simulator orientation is landscape which is correct. However, the content is 90 degrees wrong, but they are right in the storyboard view, landscape. Is there anything I need to check?
I set my storyboard as landscape.
May project I already set "supported interface orientations" = landscape
Also used this code in view controller:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight)
return YES;
else
return NO;
}
Make sure "Initial interface orientation" set in your Info.plist as well.
Supported Interface Orientations is one thing. It didn't work for me until I did the following:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
You have to use the following code on ALL of your viewcontrollers
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation==UIInterfaceOrientationLandscapeLeft || interfaceOrientation==UIInterfaceOrientationLandscapeRight)
}
