Displaying ImagePickerController From ActionSheet on iPad

Question

Background: On iPad, I have a button which when tapped, showed a UIActionSheet. This action sheet has 2 options, camera and gallery. Camera when tapped, pulled up a camera and everything works fine. Gallery when tapped, suppose to show a popover with user's photos in it.

Problem: On iPad, UIActionSheet acts like a popover. Which when presenting, another popover cannot come into view. Error:Terminating app due to uncaught exception 'NSGenericException', reason: '-[UIPopoverController dealloc] reached while popover is still visible.

My code:
Setting Action Sheet

- (void)imageButtonTapped:(UIButton *)sender
{
    if (_commentObject.image){
        _actionSheet = [[UIActionSheet alloc] initWithTitle:@"Action" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:@"Remove" otherButtonTitles:nil];
        _actionSheet.tag = ACTION_IMAGE_REVIEW_TAG;
    }else{
        _actionSheet = [[UIActionSheet alloc] initWithTitle:@"Image Source" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Camera", @"Gallery", nil];
        _actionSheet.tag = ACTION_IMAGE_SOURCE_TAG;
    }

    if (_isPad) {
        [_actionSheet showFromRect:_imageButton.frame inView:_scrollViewContent animated:YES];
    }else{
        [_actionSheet showInView:self.view];
    }
}

Delegate

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    switch (actionSheet.tag) {
        case ACTION_IMAGE_SOURCE_TAG:
            switch (buttonIndex) {
                case 0:
                    [self pickImage:YES];
                    break;
                case 1:
                    [self pickImage:NO];
                    break;
                default:
                    break;
            }
                break; 
}

Executing

- (void)pickImage:(BOOL)fromCamera
{
    if (fromCamera) {
        if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
            UIImagePickerController* cameraPickerController = [[UIImagePickerController alloc] init];
            cameraPickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
            cameraPickerController.delegate = self;
            [self presentViewController:cameraPickerController animated:YES completion:nil];
        }else{
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Camera Unavailable" message:@"Your Device does not support Cameras" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
            [alert show];
        }
    }else{
        UIImagePickerController *galleryPickerController = [[UIImagePickerController alloc] init];
        galleryPickerController.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        galleryPickerController.delegate = self;

        if (_isPad) {
            if ([_actionSheet isVisible]) {
                [_actionSheet removeFromSuperview];
                UIPopoverController *imagePickerPopover = [[UIPopoverController alloc] initWithContentViewController:galleryPickerController];
                [imagePickerPopover presentPopoverFromRect:_imageButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
            }
        }else{
            [self presentViewController:galleryPickerController animated:YES completion:nil];
        }
    }
}

Question: I tried removing the action sheet from view, and tried dismissing it before executing pickImage. None of that works. How do I present the gallery?

Answer 1

FYI, This was a comment and OP asked to put it as an answer. Because this solved the issue.

It's happening because you don't have a reference to your UIPopoverController. Have a strong reference for your imagePickerPopover and then try. No problem will occur.
