How to set photo taken with UIImagePickerController to be viewed/modified into a custom UIViewController?

Question

I am currently using the default UIImagePickerController, and immediately after a picture is taken, the following default screen is shown:

My question is, how would I be able to use my own custom UIViewController to view the resultant image (and therefore bypass this confirmation screen ).
Please note that am not interested in using a custom overlay for the UIImagePicker with custom camera controls or images from photo gallery, but rather just to skip this screen and assume that the photo taken is what the user would have liked.

Thanks!

Try this code to maintain your resultant image in same size:

First create IBOutlet for UIImageview.

-(void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSString *mediaType = info[UIImagePickerControllerMediaType];

    [self dismissViewControllerAnimated:YES completion:nil];


    if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
        OriginalImage=info[UIImagePickerControllerOriginalImage];
        image = info[UIImagePickerControllerOriginalImage];
//----------
            imageview.image = image; // additional method
            [self resizeImage];


//---------
        if (_newMedia)
            UIImageWriteToSavedPhotosAlbum(image,self,@selector(image:finishedSavingWithError:contextInfo:),nil);

    }
    else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie])
    {
        // Code here to support video if enabled
    }

}



//---- Resize the original image ----------------------
-(void)resizeImage
{

        UIImage *resizeImage = imageview.image;

        float width = 320;
        float height = 320;

        CGSize newSize = CGSizeMake(320,320);
        UIGraphicsBeginImageContextWithOptions(newSize,NO,0.0);
        CGRect rect = CGRectMake(0, 0, width, height);

        float widthRatio = resizeImage.size.width / width;
        float heightRatio = resizeImage.size.height / height;
        float divisor = widthRatio > heightRatio ? widthRatio : heightRatio;

        width = resizeImage.size.width / divisor;
        height = resizeImage.size.height / divisor;

        rect.size.width  = width;
        rect.size.height = height;

        //indent in case of width or height difference
        float offset = (width - height) / 2;
        if (offset > 0) {
            rect.origin.y = offset;
        }
        else {
            rect.origin.x = -offset;
        }

        [resizeImage drawInRect: rect];

        UIImage *smallImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    imageview.image = smallImage;
    imageview.contentMode = UIViewContentModeScaleAspectFit;
}
