The app only supports landscape. First, I have a view controller. Inside it, I have a bottom bar view controller. When I click the bottom bar view controller, a settings view controller(modal view) appears. Then if I rotate 180 degrees, the settings view controller does rotate while the original view controller is upside down. Any ideas to fix it? This is only on iOS 7(not iOS 8).
In your settings view controller try this:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotate {
return NO;
}
You can try also UIInterfaceOrientationMaskLandscapeLeft or UIInterfaceOrientationMaskLandscapeRight if you supports only one landscape orientation.

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 used this code for forcing my Home screen (first screen of my application) be portrait while other screens remain supporting all orientations:
public class RltNavigationController : UINavigationController
{
public RltNavigationController () : base ()
{
}
public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations ()
{
if(this.TopViewController is HomeScreen )
return UIInterfaceOrientationMask.Portrait ;
else
return UIInterfaceOrientationMask.AllButUpsideDown ;
}
public override bool ShouldAutorotateToInterfaceOrientation (UIInterfaceOrientation toInterfaceOrientation)
{
// Return true for supported orientations
if(this.TopViewController is HomeScreen )
return (toInterfaceOrientation == UIInterfaceOrientation.Portrait );
else
return (toInterfaceOrientation != UIInterfaceOrientation.PortraitUpsideDown) ;
}
}
Now, suppose that the device is on the landscape orientation at home screen (Device is lanscape but screen just show portrait). Now if user go to other views, other views now show portrait while it should show landscape. What solution I can choose in order to load second views with theirs actual rotation?
EDIT
Thanks for all answers, Just notice that already the problem is not that I can not force the screen to be portrait. For understanding the problem please follow the scenario:
-> First screen forced to be portrait.
-> Device is landscape right and I'm in home screen(so home screen show portrait)
-> Now I switch to another screen that support all orientation
-> at another screen because the parent screen was portrait it show portrait (while because device is landscape it should show landscape)
You can also directly select from the XIB a particular viewController be Landscape or Portrait and the same loads.
You can not explicitly say, viewController be landscape and the view will be landscape. The way it works is, you ask the controller that is controller the screen, this may be a navigation controller, tab view controller, a modal, how they want to be able to rotate. If you have a navigation controller then all viewController will only have the rotation of your navigation controller.
There were a few tricks like subclassing the navigation controller and over the should auto rotate method, call [self.visibleViewController shouldAutoRotate]; which works for making screens rotate and not rotate, but if you have only 1 screen that supports all orientations and all the others do not, then you have a pushing/popping error where if you push or pop while in that different orientation the next viewController will be in that orientation.
Since you can't directly tell the rootViewController to explicitly rotate, the next best solutions are,
A: Use QuartzCore to manually rotate the view yourself
B: have a separate xib file for each orientation so when you rotate to landscape you see the landscape viewController and vice versa
The easiest way to do this is to create a custom navigation controller (subclass of UINavigationController) that inherits its rotation based on the currently visible view controller
Inside your custom navigation controller:
-(NSUInteger) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
-(BOOL) shouldAutorotate {
return self.topViewController.shouldAutorotate;
}
Then inside any of the view controllers within that, add these methods:
-(BOOL)shouldAutorotate{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationPortrait;
}
That's for a view you DON'T want to autorotate. Modify that accordingly for views you do want to rotate.
Make sure your project settings have rotation in the orientations you want enabled, and make sure to use your custom navigation controller instead of the regular one for any view hierarchies that contain multiple possible rotations.
Note that you may run into problems if a view that is rotated is popped and the previous view is not rotatable. Off the top of my head, I'm not sure whether this will work properly.
I am using a Tab Bar Controller in my app. In the most part of the app's behavior we have one single orientation (interfaceOrientationPortrait). But i have a view that runs a video in WebView. When i am running this video, the orientation remains portrait. I want to put for all orientations.
Well, i used the return type YES in my Video's class. Nothing has changed. I changed the return type to YES in my RootViewController class. Nothing has changed.
I would like to change the orientation only for the Video.
View controllers that are part of a tab bar controller won't rotate to an orientation if any of the tab bar controllers can not rotate to that orientation (at least if the tab bar is visible). So maybe you want to update all your controllers' method in order to let the rotation happen if the web view controller is visible on the tab bar controller.
If you need a deeper explanation, just ask. Good luck!
Edit (example code)
This is what could be your rotation methods for your tab bar controller view controllers:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ((self.tabBarController.selectedIndex == kMyWebViewControllerIndex))
{
return YES;
} else
{
return (orientation == UIInterfaceOrientationPortrait);
}
}
Is your web view in a view controller inside the tabBarController?
Try showing it in a modally presented view controller, it should work
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);
}
The animation of pop view controller in iPad is changed unexpectedly from sliding from right to left to sliding from bottom only in Landscape mode. What could be the problem ?
Thank for your help.
It happened to me when I was supporting landscape and portrait, but on the viewcontrollers "supportedInterfaceOrientations" method I was returning "UIInterfaceOrientationMaskPortrait"
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
This fixed it for me:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
