animate rotation UIImageView in swift

Question

I\'m trying to animate a rotation of 180 degrees of a UIImageView in Swift

    UIView.animateWithDuration(1.0, animations: { () -> Void in
              


        

Answer 1

Try calling arrowImageView.layoutSubviews(), see below:

    UIView.animateWithDuration(1.0, animations: { () -> Void in
        self.arrowImageView.transform = CGAffineTransformMakeRotation(CGFloat(180 * M_PI))
        self.arrowImageView.layoutSubviews()
    }) { (succeed) -> Void in

    }
