UIImageView resizes in landscape mode orientation programmatically

I have a problem when I need to rotate UIImageView and resize depending on the mode of Portraite or Landscape.

I managed to get the image to rotate correctly, making the answer in this related problem: Rotate UIImageView depending on the orientation of the iPhone .

This is my code for rotation (now I focus only on turning it to the left):

- (void)rotateImage:(UIImageView *)image duration:(NSTimeInterval)duration 
          curve:(int)curve degrees:(CGFloat)degrees
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:duration];
    [UIView setAnimationCurve:curve];
    [UIView setAnimationBeginsFromCurrentState:YES];

    float angle = DEGREES_TO_RADIANS(degrees);    
    CGAffineTransform transform = CGAffineTransformRotate(
                        CGAffineTransformMakeTranslation(
                                                         160.0f-self.view.center.x,
                                                         240.0f-self.view.center.y
                                                         ),angle);
    image.transform = transform;
    [UIView commitAnimations];
}

How I run UIImageView:

UIImage *image = [UIImage imageNamed:@"picture.png"];
self.testImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 400)];
self.testImageView.image = image;
self.testImageView.contentMode = UIViewContentModeScaleAspectFit;
self.testImageView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

Now it happens that the image is rotated, but it is the same size as in portrait mode in landscape mode, but concentrated (I understand why, because I made a rotation as an answer to a related question).
