UIImageView.animationImages displaying images with rotation

I have a UIImageView that should animate an array of images called capturedImages. I have the animation set up like so:

imageView = [[UIImageView alloc] init];
imageView.frame = CGRectMake(0, 48, 320, 520);
imageView.animationImages = capturedImages;


imageView.animationDuration = 3.0;
imageView.animationRepeatCount = 0; //animate forever
[imageView startAnimating];

[self.view addSubview:imageView];

The images in capturedImages are taken with the phone/camera view upright. However, when the imageView displays them, they animate properly but are rotated 90 degrees counterclockwise. Is there a way to change the orientation of animationImages, or do I have to set each image's orientation individually?

Setting the image property for the UIImageView to the first image in the list of images fixes the problem. For example in my view controller (swift):

override func viewDidLoad() {
    super.viewDidLoad()

    if let images = self.images {
        if images.count > 0 {
            self.animation_view.image = images[0]
        }

        self.animation_view.animationImages = images
        self.animation_view.animationRepeatCount = 0
        self.animation_view.animationDuration = 1.0
    }
}

override func viewWillAppear(animated: Bool) {
    self.animation_view.startAnimating()
}

The simplest solution may be to just rotate the UIImageView itself.
You can use the transform property of UIView to do this:

[imageView setTransform:CGAffineTransformMakeRotation(M_PI_2)];

Be aware of the fact that this will break if you start displaying images which are already in the correct orientation. These will be rotated 90 degrees clockwise as well.
