The car is not moving, just the tire. (like the picture)

Im doing something similar to this but not sure if it will work for you as the tire is at an angle...
Basically I have created a seperate image with just the wheel and layered it in Interface Builder on top of the background in the exact spot it would have been in the original picture.

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:WHEEL_DURATION_SECONDS];
	
// rotate the wheel
CGAffineTransform transform = wheelView.transform;
transform = CGAffineTransformRotate(transform, (M_PI));
wheelView.transform = transform;
	
[UIView commitAnimations];

I think I understand,
but to understand more deep,
could you explain step by step, line by line please ?

very grateful.
