please help with this noob questions but really making me go crazy>
if I create a project from scratch (using windows based app) for the ipad,
and add a tabbar , with firstviewController, and secondviewController, it works fine,
starts in landscape mode,
but in info.plist I set it to Landscape(left home button),
but really in simulator starts with the button on the right side!
in the FirstViewController.m
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationLandscapeRight)
return YES;
else {
return NO; }}
so it starts in landscape, and rotates as the simulator rotates,
but if I create a template app for iphone tabbar,
set the info.plist
Initial interface orientation> Landscape (left home button)
and add the code above, IT DOESNT WORK!!!
simulator starts with button at left but tab bar on the side,
same problem that I had with an app that Im porting from iphone to ipad, (landscape intended)
I get to the landscape start mode, but the tab bar remains on the side!
also the only way to make the old ported app to show the simulator on the side was with
UIInterfaceOrientation UIIntefaceOrientationLandscapeLeft (didnt work with Initial interface orientation), does not let me choose the value for the key, but it shows the simulator on landscape,,
so,,
what can I do please to show the tab bar on landscape mode???
the tabbar from scratch was made to see if the code will work , but it didnt??
why does it work in the tab bar made from windows app and not tab bar app?
I just want the tab bar to show in landscape ahhh,
thanks
in the info.plist set Supported Interface Orientations

My application was written for iOS7 and I am trying to get it updated to iOS 8. My application is configured to only work in Landscape Left and Landscape Right orientations.
For iOS 8 I changed the order by which the screens are navigated and changed one of the modal screens to a push transition. On the main screen I have two UIBarButtonItems on the UINavigationItem. Each of these have a push segue assigned to them that connects to different screens.
When the app is running and one of the UIBarButtonItems is tapped, the screen associated through the segue slides over the main screen as expected. The back button is displayed normally. The problem occurs when the back button is tapped. The screen does not slide off to the right as would be expected.
On an iPhone 4 running iOS 7 the screen always slides down (towards the ground) regardless of the devices landscape left or landscape right orientation.
On an iPhone 6 Plus running iOS 8 the called screen quickly rotates to Upside Down (top towards the home button) and then slides off to home button side. Again it doesn't matter which way the phone is oriented landscape left or landscape right orientation.
I have tried setting the preferredInterfaceOrientationForPresentation, shouldAutorotate to NO, and setting the supportedInterfaceOrientations to UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeRight. Nothing seems to make any difference at all.
My screen navigation is straight forward, I'm no using any custom transitions. It's all through standard push segues.
I need to get the screen "back" transitions working correctly again.
Any help is greatly appreciated!
I have finally discovered what was causing my screens to slide the wrong direction. It turns out that overriding the supportedInterfaceOrientations method in the UIViewController and returning UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft confuses the transition in iOS 8 (and devices running iOS 7 also). This was needed for proper operation in iOS 7, but evidently causes problems in iOS 8. So once I removed the code, the screen transitions began working correctly again.
In my app I'm using UI for several first screens, and then switch to OpenGL view controller (cocos3d). I show status bar for UI view controllers, and then hide it before switching to OpenGL.
The strange thing is, that while running the app on iPhone all is good, but on iPad the hidden status bar starts to intercept all touches within its bounding box.
I have found this question, which refers to this one. There seems to be a bug of Simulator with the same behavior, but I encounter this on real devices (both iPhone and iPad are real devices).
I'm creating OpenGL view controller programmatically without differentiating like
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
In my .plistI have:
View controller-based status bar appearance = NO
To hide status bar I'm using:
[[UIApplication sharedApplication] setStatusBarHidden:NO];
Also, I'm targeting iOS 7.
I've almost got crazy about this, does someone encountered the same issue? How can I allow touches for status bar area?
Try putting this in the .m of the viewcontroller
- (BOOL)prefersStatusBarHidden {
return YES;
}
My app is entirely designed for IOS6. I use an xib for the iPhone and another one for the iPad. My AppDelegate sets up a TabBarController, though there is no class for the TabBarController itself. The TabBarController has two tab items, 1 a NavigationController, and 1 a View Controller, each of which has its own class. I would like the iPad to be able to run in just Portrait mode, upside down, and normal. On the summary tab of Target in Xcode, I have supported interface orientations set to Portrait and Portrait Upside Down.
My understanding with iOS 6 is that you only need to put
- (NSUInteger)supportedInterfaceOrientations
in the highest parent controller of a class, and set which Masks you would like it and all the child containers to work with. So, in the Root View Controller of the Navigation Controller I put:
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskPortraitUpsideDown;
}
And in each of the child classes, I put:
- (BOOL)shouldAutorotate{
if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
{
return YES;
}
else
{
return NO;
}
}
I then put the same two methods in the 2nd Tab which was just a View Controller Class.
I installed the app on my iPad, and it worked fine in portrait mode, but did not rotate when I turned it upside down. I exited the app and turned the iPad upside down, but when I started the app again, it still stayed in the same spot. So, I killed the app completely, and started it from the beginning upside down. The splash screen was upside down, but when the screen disappeared, the app was still only showing in portrait mode, making the display upside down.
What am I missing?
click on appName select Target and just select the orientations which you want to support. thanks
The code above is great for pre iOS 6. For iOS 6 you have to use the mask orientation. If you want all of the views in iPad to rotate or just some you have the choice of using the above answer. If you want to hard code it the check my answer in the following link for a detailed code for autorotation of all masks or just rotate one view and let the others don't rotate. Any how here is the link
iOS 6 supportedInterfaceOrientations issue
The above answer is providing you with the right solution as well but if you want to learn how to code it check my answer in the link above. Happy coding.
Is the Rotation Lock enabled or not ? (If you are new to iOS, double tap the home button, and slide to the right: it's the little metal-styled button in shape of an arrow).
If you want to run your application to run on portrait mode only than,
1. Select Your Target.
2. In General -> Development Info -> Device Orientation Uncheck all other orientation.Portrait mode only should be checked.Than run your project.
I searched for other existing posts, but none of them satisfied my requirements.
Here is the problem i face,
My app supports both the Modes , landscape and portrait.
But my first screen only supports Landscape , so the app must start in Landscape.
I have set supported Orientation to all the 4 options
I have set the Initial interface orientation to Landscape (left home button)
In the view controller of the first screen i am defining the below
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation != UIInterfaceOrientationPortrait);
}
And when i start the app the simulator always opens in Portrait and my view is all messed up in the portrait mode , since it is designed only for the landscape.
After the switch to the Landscape, the device remains in this mode.
can anyone help me with the solution to avoid this ?
Thanks
Naveen
EDITED :
This info may be helpful , The problem is faced only when i hold the device in Portrait and then launch the app.
Its not the duplication of this question, Landscape Mode ONLY for iPhone or iPad
Landscape Mode ONLY for iPhone or iPad
I do not want my app to be only in Landscape , i want only the first screen of my app to be only in Landscape.
I did some experimenting with an app I'm working on that has the same requirements, and came up with the following:
To set the initial orientations that are supported when the app is first launched, use the "Supported Device Orientations" setting for your target.
Also back that up with the appropriate shouldAutorotateToInterfaceOrientation code, as you've already done.
For subsequent screens, simply use the shouldAutorotateToInterfaceOrientation code to determine which orientations you want to support. Even if you've specified only landscape modes for the Supported Device Orientation, shouldAutorotateToInterfaceOrientation wins. :)
I think this approach is a little cleaner than using an extra dummy VC.
I achieved a workaround for the Problem and it solved ,
I created a dummy view controller and added as the root view controller of the Window.
Added the below method in the implementation
-(void)viewDidAppear:(BOOL)animated
{
WelcomeScreen *welcomeScreen = [[[WelcomeScreen alloc] initWithNibName:#"WelcomeScreen" bundle:nil] autorelease];
[self presentModalViewController:welcomeScreen animated:NO];
}
Now it worked as expected.
Here is a SO link that will hopefully answer your question on how to launch your app in landscape mode.
I settings my info.plist as below:
Initial interface orientation: Landscape (left home button)
Supported interface orientations: Landscape (left home button) and Landscape (right home button)
When I started my app, the orientation device have landscape mode, but my view not rotate to this orienatation.
I use method below for rotate orientation, but view not initial in landscape mode (after I have rotate my device in this case I had needed result - view rotate in landscape mode)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
I've had a couple of issues with this in the past. Basically if you just put the initial view controller there it bugs out handling as if it was in portrait mode. The fix i found for this was adding the view controller to a navigation controller.
See this question i posted for the full explanation
