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

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.

My app’s device orientation is set to portrait, however when rotating the device into landscape mode, the app is keeping its portait mode but the keyboard is rotating into landscape mode...Something that is unexpected.
Why is that happening and how to prevent it?
Thanks

After not getting any answer and making more researches, I came across this Answer:

Because I just needed the portrait orientation in my app the following worked for me :
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
I put that in my main Navigation Controller's viewDidLoad.
I know it's late. But maybe it will help someone else. I had the similar issue. My app should support portrait orientation for iPhone and all orientations for iPad. So, on the iPhone scene didn't rotate, but keyboard did. All my UI was made from code, I also init view controllers (including root) through code. But I didn't remove default Main.storyboard file. When I removed string in Target -> General -> Main Interface, it help me. It was not obvious.
I have 2 root view controllers ViewController1 and TabBarController1(there are reasons for making 2 root view-controllers). ViewController1 only supports Portrait mode and TabBarController1 supports all orientations. ViewController1 appears first after launch. I am locking the orientation of ViewController1 using the following method.
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
The app launch and orientation worked fine with iOS7.
When building the app through Xcode 6 in iPad(iOS8) following change is observed:
- When app is launched in landscape mode, ViewController1 with orientation locked into portrait mode appears with half black screen and when TabBarController1 appears which supports all orientations, doesn't resize with proper dimensions on changing orientations.
I have also tried overriding the above method in TabBarController1 to support all orientation but nothing works fine.
This problem is not observed when launching the app on iPad in portrait mode.
There is no problem when launching the app on iPhone as iPhone launches only in Portrait mode.
What is the issue when working with iOS8 ?
I am a newbie, so don't judge..
In ios8, apple changed 2 things :
1-
[[UIscreen mainscreen] bounds].size
This used to be a fixed value for portrait and landscape, now it is not.
When u change from landscape to portrait the width and height switch.
2-What is happening with you. You cannot force a viewcontroller to be in portrait only if you set portrait and landscape in project settings, do not know why, so you maybe have to set portrait only in project settings for example..
This is happening on iPads and iphone 6+ only.
Hope this helped..
I know that we can define main orientation in iOS apps. However I couldn't figure out a way to do what I want: If the device is in landscape mode, start the whole application in landscape mode. If not, start it in portrait.
Currently, if I start the application after rotating the device into landscape mode, It opens in portrait mode than it rotates. Is there a way to start the whole app in landscape? (Already rotated window)
Yes; just indicate that you support all device orientations in your info.plist. You can see this in Xcode in your project settings under "General" in Xcode 5.
Quote from Apple's UIViewController documentation:
Note: At launch time, apps should always set up their interface in a portrait orientation. After the application:didFinishLaunchingWithOptions: method returns, the app uses the view controller rotation mechanism described above to rotate the views to the appropriate orientation prior to showing the window.
I am almost done developing an app. Right now I'm converting it to a universal app by supporting iPad to supported devices as well.
Can I set the app to use Landscape orientation only, since I am using UISplitViewController and want the Master View Controller to remain on the screen all the time? Is there any Apple policy that states that I cannot restrict it to Landscape only and I have to implement both portrait and landscape? Is there any chance my app can be rejected by setting it to Landscape only for iPad?
Don't worry, you'll be fine. Support both landscape orientations and neither portrait orientation if you want. I've got apps in the store that are like that.
However, note that UISplitViewController does have an option to keep both views on the screen all the time even in portrait. Use the delegate method splitViewController:shouldHideViewController:inOrientation: to forbid hiding the master view:
http://developer.apple.com/library/ios/#documentation/uikit/reference/UISplitViewControllerDelegate_protocol/Reference/Reference.html#//apple_ref/occ/intf/UISplitViewControllerDelegate
So if your only reason for being landscape only is that you don't want to hide the master view, it is a false reason. Look, for example, at Apple's Settings app, which works like that; it is a split view controller that always shows both views in all four orientations.
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.
