Application Crashes on Cancelling Message Composer Or Mail Composer view - ios

Question

My application is is landscape mode. I am presenting the activity view controller in landscape only with the following lines of code:-
NSArray *shrArr = [NSArray arrayWithObjects:[NSString stringWithFormat:#"%#", KHL_SHARE_TEXT], nil];
UIActivityViewController *shareUIAVC = [[UIActivityViewController alloc] initWithActivityItems: shrArr applicationActivities: nil];
if([shareUIAVC respondsToSelector:#selector(setValue:forKey:)])
{
[shareUIAVC setValue:KHL_SHARE_MAIL_TEXT forKey:#"subject"];
}
if([shareUIAVC respondsToSelector:#selector(popoverPresentationController)])
{
shareUIAVC.popoverPresentationController.sourceView = self.menuButton;
shareUIAVC.popoverPresentationController.sourceRect = self.menuButton.bounds;
}
[self presentViewController:shareUIAVC animated: YES completion: nil];
The Activity view controller opens in landscape and on choosing either message or mail and either sending or cancelling the message or mail composer, the app crashes with the following logs.
* Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation '(7)' must match a supported interface orientation: 'landscapeLeft, landscapeRight'!'

As suggesting from various sources here , I added the following code too, but that does'nt work either
-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
-(BOOL)shouldAutorotate
{
return NO;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
Thanks in advance!

Answer 1

Add this in appdelegate
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
//self.isMailController enable while activityViewcontroller appears and disable while it dissmissed.
if(self.isMailController){
// you can check multiple viewcontroller
return UIInterfaceOrientationMaskPortrait; // if your mail viewcontroller it will display on portrait
}
return UIInterfaceOrientationMaskLandscape;
}
