UIImageView.animationImages displaying images with rotation

I have a UIImageView that should animate an array of images called

. 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
, or do I have to set each image's orientation individually?


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.
