Camera Overlay with User-Photo not saving as edited

I am using a transparent image with a cut out for a user to insert / take their own image. For some reason, while using the UIImagePickerControllerEditedImage and cropping the 开发者_开发问答user-taken photo, the image does not save as it was edited; see photo for example.

My issue is that the image does not save exactly how the photo was edited. (i.e: cropped / resized).

Setting up the UIImagePicker

-(void)choosePhotoDialog:(id)sender
{        
    OverlayView * overlay = [[OverlayView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH_IPHONE, SCREEN_HEIGTH_IPHONE) andPhoto:[dict objectForKey:@"imageUrl"]];
    [overlay setUserInteractionEnabled: NO];

    UIImagePickerController * picker = [[UIImagePickerController alloc] init];
    [picker setSourceType: UIImagePickerControllerSourceTypeCamera];
    [picker setDelegate: self];
    [picker setAllowsImageEditing: YES];
    [picker setShowsCameraControls: YES];
    [picker setNavigationBarHidden: YES];
    [picker setWantsFullScreenLayout: YES];
    [picker setCameraOverlayView: overlay];
    [self presentModalViewController:picker animated:YES];  
    [picker release];
}

After the image is edited:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    SDWebImageManager * manager = [SDWebImageManager sharedManager];
    UIImage * cachedImage  = [manager imageWithURL: [NSURL URLWithString: @"http://www.someurl.com/test.png"]];
    UIImage * userOriginal = [info valueForKey:UIImagePickerControllerEditedImage];

    /*  combining the overlay and the user-photo  */
    UIGraphicsBeginImageContext( CGSizeMake(640,960) );

        /*  for some reason I have to push the user-photo
            down 60 pixels for it to show correctly as it
            was edited.
         */
        [userOriginal drawAtPoint:CGPointMake(0,60)];
        [cachedImage drawAtPoint:CGPointMake(0,0)];

        UIImage * draft = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    UIImageWriteToSavedPhotosAlbum( draft, self, @selector(image:didFinishSavingWithError:contextInfo:), nil );       
}

As well, there are white spaces from the editing "crop" portion as demonstrated in the following:

I believe this is because the edited photo does not include the parts obscured by the semi-transparent framing overlay that is shown as part of the standard iOS image editor. (The 60px you've found you must offset by is the 60px of the top half of this overlay.)

You can extract and expand the UIImagePickerControllerCropRect key from the info dictionary and do the edit again yourself on the UIImagePickerControllerOriginalImage in order to get the resultant image you desire.
