arrow.transform = CGAffineTransformMakeRotation(M_PI);

it works fine, but now I want this image to return to its original position; What taht value should I set to receive it?

Swift3:

arrow.transform = CGAffineTransform(rotationAngle: rotation);

where rotation is the angle of rotation in radians.

To return it to its original position, simply do the following:

arrow.transform = CGAffineTransformMakeRotation(0);

In degrees 0 radians is 0 degrees, so it should return to its original position.
