UIImagePickerController in Landscape

StackOverflow https://stackoverflow.com/questions/2083672

Question

I have been searching for an answer to this, but cannot come up with anything. Apparently, iPhone SDK 3.0 made it possible that UIImagePickerController can be displayed in landscape mode - but I am not finding any method that will allow this. I would think that if the application is in landscape by default it would automatically adjust the image controller, but that is not working for me.

Thanks for any help!

Was it helpful?

Solution

I haven't checked whether this is illegal, but it worked for me. If you want the UIImagePickerController to start(and stay) in Landscape orientation code:

//Initialize picker

UIImagePickerController * picker = [[UIImagePickerController alloc] init];
   picker.delegate = self;


//set Device to Landscape. This will give you a warning. I ignored it.
//warning: 'UIDevice' may not respond to '-setOrientation:'


[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

//Set Notifications so that when user rotates phone, the orientation is reset to landscape.
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];

//Refer to the method didRotate:   
[[NSNotificationCenter defaultCenter] addObserver:self
              selector:@selector(didRotate:)
               name:@"UIDeviceOrientationDidChangeNotification" object:nil];

//Set the picker source as the camera   
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

//Bring in the picker view   
[self presentModalViewController:picker animated:YES];

The method didRotate:

- (void) didRotate:(NSNotification *)notification

{
      //Maintain the camera in Landscape orientation
 [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight];

}

OTHER TIPS

No need to subclass; simply override the modalPresentationStyle property.

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.modalPresentationStyle = UIModalPresentationFormSheet;
    [viewController presentViewController:picker animated:YES completion:NULL];

If you just need to get rid of the warning try

@interface UIDevice ()
    -(void)setOrientation:(UIDeviceOrientation)orientation;
@end

I've developed a UIImagePicker class in landscape mode. Works great for applications I've developed: hope it works for you too:

I have an all-landscape app using UIImagePickerController too. Please be noted that if you call UIImagePickerController in Landscape mode, your app is possible to be rejected by Apple Review Team.

I devised a simple work around this issue which make use the shouldAutoRotate delegate. Apple approves this method for an all-landscape app.

See here for the details and downloadable full project source code.

Make a category of UINavigationController and add this method

- (BOOL)shouldAutorotate
{
    return NO;
}

Subclass UIImagePickerController and override modalPresentationStyle as follows:

- (UIModalPresentationStyle)modalPresentationStyle
{
    if([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad)
    {
        return UIModalPresentationFormSheet;
    }

    return [super modalPresentationStyle];
}

The image-picker is a form-sheet now and no longer in fullscreen-mode, but it looks good in landscape-mode. This should be totally app-store-safe.

This works for the gallery, not for taking pictures.

I solved this problem as follows: after each change in orientation, I simple re-create picker. Try this. Differently is too crooked...

I am developing a class that tries its best to work in landscape mode. Check it out on GitHub: RACameraController
