你想旋转，那么你要对旋转的图像做什么？
如果您只想在视图中显示它，请将其包装在 中UIImageView，旋转 imageView 并插入到视图中：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    UIImage* image = [[info objectForKey: UIImagePickerControllerOriginalImage] fixOrientation];
    UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
    imageView.transform = CGAffineTransformMakeRotation(M_PI * 90 / 180);
    [self.view addSubview:imageView];
}
