viewDidLoad中的CGAffineTransformRotate拉伸/分散UIImageView(CGAffineTransformRotate in viewDidLoad stretches/distords the UIImageView)

 我需要在加载视图时按接口构建器创建的UIImageView以给定角度旋转。 
 
- (void)viewDidLoad
{
   [super viewDidLoad];
    image.transform = CGAffineTransformRotate(image.transform, REF_INIT_OFFSET*M_PI/180); 
}
 
 这会旋转图像，但后者完全扭曲和拉伸。 如果REF_INIT_OFFSET是90的倍数，它工作正常！ 
 
 这是图片的样子（注意指针指向“0”） 
 
 
 以下是它的实际外观： 
 
 
 看起来图像被拉伸到错误的方向。 
 
 你知道什么是错的吗？ 
 
 谢谢， 

I need to rotate by a given angle a UIImageView created by Interface builder when the view is loaded.
 
- (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 and stretched. If REF_INIT_OFFSET is a multiple of 90 it works fine ! 
 
Here is how the picture should look like (note the needle pointing to the "0")
 
 
and here is how it actually looks:
 
 
it looks like the image is stretched into a wrong direction.
 
Do you have in idea what's wrong ?
 
thanks,
