UIView changing its position in swift - ios

Question

How do I make a UIView slide up with a touch of a button from its original position and them bring it back down with a touch of a button? Using Swift and Xcode 6.
I have currently tried this:
#IBOutlet weak var DynView: UIView!
#IBAction func btnUp(sender: AnyObject) {
}

Answer 1

You have to implement an animation changing the DynView position on click. Here's an example:
#IBAction func btnUp(sender: AnyObject) {
let xPosition = DynView.frame.origin.x
let yPosition = DynView.frame.origin.y - 20 // Slide Up - 20px
let width = DynView.frame.size.width
let height = DynView.frame.size.height
UIView.animateWithDuration(1.0, animations: {
dynView.frame = CGRect(x: xPosition, y: yPosition, width: width, height: height)
})
}

Hi create this extends if you want. For Swift
Create File Extends.Swift and add this code
/**
Extension UIView
by DaRk-_-D0G
*/
extension UIView {
/**
Set x Position
:param: x CGFloat
by DaRk-_-D0G
*/
func setX(#x:CGFloat) {
var frame:CGRect = self.frame
frame.origin.x = x
self.frame = frame
}
/**
Set y Position
:param: y CGFloat
by DaRk-_-D0G
*/
func setY(#y:CGFloat) {
var frame:CGRect = self.frame
frame.origin.y = y
self.frame = frame
}
/**
Set Width
:param: width CGFloat
by DaRk-_-D0G
*/
func setWidth(#width:CGFloat) {
var frame:CGRect = self.frame
frame.size.width = width
self.frame = frame
}
/**
Set Height
:param: height CGFloat
by DaRk-_-D0G
*/
func setHeight(#height:CGFloat) {
var frame:CGRect = self.frame
frame.size.height = height
self.frame = frame
}
}
For Use (inherits Of UIView)
inheritsOfUIView.setX(x: 100)
button.setX(x: 100)
view.setY(y: 100)

I kinda combined the two most voted answers into one and updated to Swift 3. So basically created an extension that animates a view moving to a different position:
extension UIView {
func slideX(x:CGFloat) {
let yPosition = self.frame.origin.y
let height = self.frame.height
let width = self.frame.width
UIView.animate(withDuration: 1.0, animations: {
self.frame = CGRect(x: x, y: yPosition, width: width, height: height)
})
}
}

// MARK: - Properties
var bottomViewHeight: CGFloat = 200
var isViewHide = false
private let bottomView: UIView = {
let view = UIView()
view.backgroundColor = .red
view.translatesAutoresizingMaskIntoConstraints = false
return view
}()
private let showHideButton: UIButton = {
let button = UIButton()
button.setTitle("Show / Hide", for: .normal)
button.setTitleColor(.black, for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
button.addTarget(self, action: #selector(showHideButtonTapped(_:)), for: .touchUpInside)
return button
}()
// MARK: - Lifecycle
override func loadView() {
super.loadView()
view.addSubview(bottomView)
NSLayoutConstraint.activate([
bottomView.heightAnchor.constraint(equalToConstant: bottomViewHeight),
bottomView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor),

])
view.addSubview(showHideButton)
NSLayoutConstraint.activate([
showHideButton.widthAnchor.constraint(equalToConstant: 200),

}
override func viewDidLoad() {
super.viewDidLoad()
showHideView(isShow: isViewHide)
}
// MARK: - Selectors
#objc func showHideButtonTapped(_ sender: UIButton) {
print("👆 HIDE / SHOW BUTTON")
showHideView(isShow: isViewHide)
}
// MARK: - Functions
private func showHideView(isShow: Bool) {
if isShow {
UIView.animate(withDuration: 0.4) {
self.bottomView.transform = CGAffineTransform(translationX: 0, y: self.bottomViewHeight)
}
} else {
UIView.animate(withDuration: 0.4) {
self.bottomView.transform = CGAffineTransform(translationX: 0, y: 0)
}
}
isViewHide = !isViewHide
}
