Get the current angle/rotation/radian for a UIView?

Question

How do you get the current angle/rotation/radian a UIView has?

Answer 1

Swift:

// Note the type reference as Swift is now string Strict

let radians:Double = atan2( Double(yourView.transform.b), Double(yourView.transform.a))
let degrees:CGFloat = radians * (CGFloat(180) / CGFloat(M_PI) )
