I have an iPhone application who need to run on iOS 7 and iOS 8. It's a full Portrait Application, except for the video player who is displayed thanks to a presented ViewController.
When I start the application from the landscape mode on an iPhone 6 or 6 Plus, It will cause to destroy the HomeView. All the orientation are supported in the project because of the video player (I know I can avoid the problem by removing the landscape support but my video player won't be displayed properly).
So the question is : How can I do to start my application from landscape mode without break the HomeView (so in a nice portrait mode) but at the same time still have my video player properly displayed in landscape mode ?
PS : I can't post screenshots, so when I say "destroy", just imagine the view with not well positioned and scaled elements.
How can I do to start my application from landscape mode without break the HomeView (so in a nice portrait mode) but at the same time still have my video player properly displayed in landscape mode ?
How the application is oriented on launch depends on the order in which the supported orientations are listed in the Info.plist file. Just make sure that Portrait comes first.
How the home view can be oriented depends on the root view controller's implementation of supportedInterfaceOrientation. Make sure that it returns UIInterfaceOrientationMaskPortrait.
In Info.plist set device orientation just to Portrait
In AppDelegate add -
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskAll;
}

I'm working with Xamarin and am having troubles launching my app in the current device orientation.
I have a UINavigationController that I set on my main UIWindow as the root controller. I created a custom UINavigationController which overrides the methods :
GetSupportedInterfaceOrientations
and
ViewWillTransitionToSize
If I hold my iPad in landscape mode and start the app, it will start in portrait mode and then rotate in landscape. I'd like to make it start in the same orientation as the device's physical orientation. From the doc I've read it seems that since iOS 8, everything related to rotations should be handled in the root uiview controller which is my custom UINavigationController.
And here's my problem... let's say I want to start my app in the current device's orientation and then block everything except Portrait once the app is loaded. I tried the 2 following solutions and none worked.
1- I put all interface orientations available in the supported interface orientations key in the info.plist file. I launched the app while holding the iPad in landscape mode. In this case, my app starts in the same orientation as the device which is cool. What is not cool is that it doesn't call my navigation controller method GetSupportedInterfaceOrientations anymore. So even if I change the return value of that method to Portrait only later one, it does absolutely nothing since the method is never called anymore.
2- I removed all supported interface orientations from the info.plist file. I lauched the app while holding the iPad in landscape mode. In this case, my app starts in portrait mode and then rotates to landscape. I want to prevent the rotation and just start the app in the current device's orientation (landscape). With this setup though, I can later change the supported orientation as the navigation controller method GetSupportedInterfaceOrientations is being called everytime we try to rotate the app.
In apple's doc, it says "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."
The part where the view rotates to the appropriate orientation PRIOR to showing the window doesn't seem to work for me. It shows the window and then rotates it after.
So how do you launch an app in the current device's orientation (without the user seeing your first view rotate from portrait to whatever) and then be able to change the supported orientations later in the app? Example : I hold my iPad in landscape mode. I launch my app. First view I see is already in landscape mode. I can then rotate my iPad to change the view in portrait/landscape back and forth. Then I click a button which changes the supported orientation to Portrait which prevents me from changing the orientation to Landscape anymore.
Thanks!
I have an iPad kiosk app that displays video on an external monitor connected via an HDMI cable. The device orientation is set to Landscape Left or Landscape Right in the apps general settings. I want the app to be displayed in landscape on the iPad and on the external monitor. When I run the app in iOS7 the external monitors view controller is displayed correctly in landscape orientation, but when run under iOS 8 the external monitor's view controller is rotated 90 degrees counterclockwise, into portrait orientation.
How do I force the external monitor to the correct landscape orientation? What has changed between iOS 7 and 8 to cause this behavior?
I've had a similar issue with a landscape-only iPad app that supports airplay. On the iPad screen, everything was working fine, but on the external display, starting # iOS 8.0, orientation issues started happening. I tried many things, what ended up helping was these two fixes:
On the shouldAutorotate method of your ViewController, return NO.
Implement the application:supportedInterfaceOrientationsForWindow: method:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)_window
{
if ([UIScreen mainScreen] == _window.screen || !_window)
{
return UIInterfaceOrientationMaskAll;
}
else
{
return UIInterfaceOrientationMaskPortrait;
}
}
The second part of the fix may require some changes on your side, since you're not using AirPlay, but I hope it can help lead you to the right solution. Good Luck!
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..
Actually I develop one iPad application. It works fine as desired. But I have orientation issue when initially application launch. Actually i put iPad flat in landscape(Horizontal) style. Now every time when application launch it will open in portrait mode. I checked with supported orientation style and other things also. I put the log in ViewDidLoad for 3 orientation, 1) viewControllerOrientation - portrait
2) ApplicationStatusbarOrientation - portrait
3) DeviceOrientation - Flat.
Now i have trouble even device is in flat mode (it really put like Horizontal) not in portrait, though why always it open in portrait mode.
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.
