How can I make image always face up?

Question

I have an image that describes a head of a monkey. I want that the head of the monkey always face up. When you turn the device the head of the monkey turns too, but I want that in spite of the rotation of the iphone the monkey head dooesn't turn (like a compass).

How can I do this?

to do rotations, with animations, this link might help.
to follow orientation of device it is another story...

probably involving compass using CLLocationManager :) :

- (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading

or better, using gyroscope

Make sure to look at Apple documentation, there and there Also give a look at Apple sample codes : enter image description here

If you want to follow the device as it turns you'll have to track with the CLLocationManager.

But if you just want the monkey to be upright as the user transistions from portrait to landscape (and their opposites) then maybe the UIInterfaceOrientation will do the trick:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    return YES;
}
