title: How to keep a UIView pointing in a certain direction regardless of device orientation?
body: <p>I have a UIView that I want to always be facing up.  So say you have an UIImageView that has an arrow, and no matter what way the device is being held, it's pointing up.  Obviously I need the accelerometer, but telling it to rotate the image based on the coordinates is only going to work the first time I think, since rotations are relative.  Is there an easier way of doing this?  I feel like there would be a simple example app somewhere that would do something like this.</p>
