Moving an Image to Origin - swift

Question

I am currently working on an animation project for an Apple Development class where we are moving and animating an ImageView. I can move the image, but I'm stumped on how to return it to the origin location, preferably using the same button.
Code for the move animation is as follows:
#IBAction func move(_ sender: Any) {
UIView.animate(withDuration: 1, animations: {self.imageView.frame.origin.y -= 200
}, completion: nil)
}

Answer 1

declare a variable that will hold the value of your y origin when the view loaded. and also declare a variable that will check if the imageview is currently animating or not.
var onLoadFrameYOrigin : CGFloat = 0.0
var isAnimating : Bool = false
override func viewDidLoad() {
super.viewDidLoad()
onLoadFrameYOrigin = self.searchView.frame.origin.y
}
#IBAction func move(_ sender: Any) {
if !isAnimating {
self.isAnimating = true
UIView.animate(withDuration: 1.0, animations: {
if self.onLoadFrameYOrigin == self.imageView.frame.origin.y {
self.imageView.frame.origin.y -= 200
} else {
self.imageView.frame.origin.y = onLoadFrameYOrigin
}
}) { _ in
self.isAnimating = false
}
}
}

Note : if you have make outlet of constraint of imageView then please
update constraint value during animation not frame.
1) make variable first
var isBack : Bool = false
Now in your button action :
#IBAction func move(_ sender: Any) {
if isBack == false
{
isBack = true
UIView.animate(withDuration: 1, animations: {self.imageView.frame.origin.y -= 200
}, completion: nil)
}
else
{
isBack = false
UIView.animate(withDuration: 1, animations: {self.imageView.frame.origin.y += 200
}, completion: nil)
}
}
