iOS CGAffineTransformRotate in viewDidLoad doesn't work

[Tex-Twil]

Hello,
I need to rotate a UIImageView of a view created by Interface builder. I have this code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    image.transform = CGAffineTransformRotate(image.transform, REF_INIT_OFFSET*M_PI/180); 
}

This rotates the image but the latter is totally distorted. if REF_INIT_OFFSET is a multiple of 90 it works fine !


Do you have in idea what's wrong ?

thanks,

it looks like the image is stretched into a wrong direction
