Rotate An Image View
This recipe shows how to rotate an image on the screen using a UIImageView and a CGAffineTransform.

Recipe

  1. Add a sample image to your project.
  2. In a UIViewController subclass, add class variables for a UIImage and UIImageView.
UIImage image;
UIImageView imageView;
  1. In the ViewDidLoad method create the UIImage and the UIImageView.
image = UIImage.FromFile("monkey.png");
imageView = new UIImageView(new CGRect(50,50,100,100));
imageView.ContentMode = UIViewContentMode.ScaleAspectFit;
imageView.Image = image;
  1. Set the Transform property of the UIImageView and add it as a sub view.
imageView.Transform = CGAffineTransform.MakeRotation((float)Math.PI/4);
View.AddSubview (imageView);

Additional Information

CGAffineTransform has helper functions to return various affine transforms such as rotation, scale and translation. Setting a CGAffineTransform to the Transform property of a UIView applies the transformation matrix to the view.
