Keyboard appears in wrong orientation in ios

Question

I have one viewcontroller in application that supports landscape and portrait orientations.

On a button click, a popup appears where I should enter the name. everything works as it should on portrait mode.

But if I dismiss the keyboard, rotate the device left or right and then open the popup, keyboard still opens in portrait mode.

I've shouldAutorotate returning true and supportedInterfaceOrientations returning AllButUpsideDown in viewcontroller, so rotation happens automatically.

I tried this and this options but none of them work.

Any ideas what to do?

Answer 1

I got exactly the same wrong keyboard orientation in some of my view controllers recently after I dropped support for iOS 8 and bumped up the deployment target to iOS 9. It turns out that one of my former colleagues used a solution here to solve an old problem when the base SDK was iOS 9 (we're now in 10, and 11 when coding from Xcode 9 beta). That solution (basically override UIAlertController's supportedInterfaceOrientations to only allow portrait) would force present the keyboard in portrait with newer SDK + deployment target even though the app window and the alert itself are in landscape.

Removing that override solved the problem and I don't see any issue with alert over alert.

Try by adding below code to your viewcontroller's viewDidAppear method

 - (void)viewDidAppear:(BOOL)animated
    {
        [super viewDidAppear:animated];
        [[UIDevice currentDevice] setValue:@(UIDeviceOrientationLandscapeLeft) forKey:@"orientation"];
        [[UIDevice currentDevice] setValue:@(self.interfaceOrientation) forKey:@"orientation"];

    }

Ok, fixed it, my fault I guess.

It seems Keyboard and UIViewController call supportedInterfaceOrientations separately and rotate based on its return value. I had an if-else statement in there and was returning AllButUpsideDown only in some cases. When keyboard checked whether it was supposed to rotate method returned Portrait, and for viewcontroller value was AllButUpsideDown.

So I changed this:

public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
    {
        if (someStatement)
        {
            return UIInterfaceOrientationMask.AllButUpsideDown;
        }
        return UIInterfaceOrientationMask.Portrait;
    }

To this:

    public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
    {
        return UIInterfaceOrientationMask.AllButUpsideDown;
    }

And now only ShouldAutoRotate decides whether it rotation should happen or not.

To some up it should look like this:

public override bool ShouldAutorotate()
    {
        if (someStatement)
        {
            return true;
        }
        return false;
    }

    public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations()
    {
        return UIInterfaceOrientationMask.AllButUpsideDown;
    }

Create subclass of UIAlertController

MyAlertController.h //header file
@interface MyAlertController : UIAlertController

@end

MyAlertController.m
@implementation MyAlertController 

- (BOOL)shouldAutorotate
{
  return NO;
}

-(UIInterfaceOrientationMask)supportedInterfaceOrientations
{
  [super supportedInterfaceOrientations];    
  return UIInterfaceOrientationMaskLandscape;
}
@end
