In a navigation controller embedded project, using animations, I cannot avoid getting a "fast preview" of the buttons present in the next ViewController, where those buttons will slide from left border of the screen to the center.
So, when I tap in first VC, see for an instant the buttons in second VC, and then the second VC appears and the animation works (and it works fine)
In home controller the button is:
#objc func imageTapped(tapGestureRecognizer: UITapGestureRecognizer)
{
print("tapped")
//animate 1/2
UIView.animate(withDuration: 0.8, animations: { () -> Void in
self.mainButtonContainerView.center.y -= self.view.bounds.width //self.view.frame.origin
self.mainButtonContainerView.isUserInteractionEnabled = false
self.mainButtonContainerView.alpha = 0.0
})
//animate2/2
DispatchQueue.main.asyncAfter(deadline: .now() + .seconds(1) ) {
self.pushShowNextVC_ChoiceVC(dataToPass: "")
}
}
Then, the animation in second VC ViewDidLoad is:
for singleView in coantinersOutCollection {
//animation
singleView.center.x -= self.view.bounds.width
singleView.layer.cornerRadius = singleView.bounds.size.height/2
singleView.backgroundColor = UIColor.white
singleView.layer.borderColor = Constants.skyBlue3Color.cgColor
singleView.layer.borderWidth = 1
}
for singleLabel in labesForButtons {
singleLabel.textColor = Constants.skyBlue3Color
singleLabel.font = UIFont.boldSystemFont(ofSize: 17.0)
}
for singleImage in self.iconButtonImages {
// singleImage.image = UIImage(named: "")
singleImage.backgroundColor = UIColor.clear
singleImage.layer.borderWidth = 1
singleImage.layer.borderColor = Constants.skyBlue3Color.cgColor
}
UIView.animate(withDuration: 1.5, delay: 0.6,

self.containerDownloadButton.center.x += self.view.bounds.width
}, completion: nil)

self.containerCallButton.center.x += self.view.bounds.width
}, completion: nil)
UIView.animate(withDuration: 1.5, delay: 0.9,
usingSpringWithDamping: 0.6,
initialSpringVelocity: 1,
options: [], animations: {
self.containerIdleButton.center.x += self.view.bounds.width
}, completion: nil)
Recently, I have made some code which draws a face. I wanted to animate the face to shake back and forth. Currently I have this code. It rotates once to the right, then more to the left, and then to the original position. However, what if I wanted the head to infinitely shake back and forth(rotate bath and forth). Is it possible to make some sort of recursive function to do this?
#IBAction func shakeHead(_ sender: UITapGestureRecognizer) {
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
},
completion:{ finished in
if(finished){
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: -(self.shakeAngle)*2)
},
completion:{ finished in
if(finished){
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
},
completion: nil
)
}
}
)
}
}
)
}
You could call shakeHead from the final completion block.
#IBAction func shakeHead(_ sender: UITapGestureRecognizer) {
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
},
completion:{ finished in
if(finished){
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: -(self.shakeAngle)*2)
},
completion:{ finished in
if(finished){
UIView.animate(
withDuration: 0.5,
animations: {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
},
completion: { finished in
shakeHead(sender)
}
)
}
}
)
}
}
)
}
Even though this is technically a recursive call, it's not a problem due to the asynchronous nature of the code.
Use animateKeyframes for a better chain animation experience
#IBAction func shakeHead(_ sender: UITapGestureRecognizer) {
UIView.animateKeyframes(withDuration: animationDuration, delay: 0, options: [], animations: {
UIView.addKeyframe(withRelativeStartTime: 0, relativeDuration: 0.5) {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
}
UIView.addKeyframe(withRelativeStartTime: 0.5, relativeDuration: 0.5) {
self.faceView.transform = self.faceView.transform.rotated(by: -(self.shakeAngle)*2)
}
UIView.addKeyframe(withRelativeStartTime: 1.0, relativeDuration: 0.5) {
self.faceView.transform = self.faceView.transform.rotated(by: self.shakeAngle)
}
}) { (isFinished) in
shakeHead(sender)
}
}
I'm trying to perform a segue in the completion block of an animation in Swift. However, the segue takes a long time(about 10 seconds) to do and I'm not sure why. Here's the code:
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
imageViewAnimated.startAnimating()
if label.center != CGPoint(x:50, y:10) {
UIView.animateWithDuration(2.0, delay: 0.0, usingSpringWithDamping: 0.0, initialSpringVelocity: 0.0, options: .CurveEaseOut, animations: { () -> Void in
self.label.center = self.view.center
}, completion: nil)
UIView.animateWithDuration(0.5, delay: 0.0, usingSpringWithDamping: 0.0, initialSpringVelocity: 0.0, options: .CurveEaseOut, animations: { () -> Void in
self.label.alpha = 0.0
}, completion: { finished in
self.poof.alpha = 1.0
self.performSegueWithIdentifier("backSegue", sender: nil)
})
}
}
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
imageViewAnimated.startAnimating()
if label.center != CGPoint(x:50, y:10) {
UIView.animateWithDuration(2.0, delay: 0.0, usingSpringWithDamping: 0.0, initialSpringVelocity: 0.0, options: .CurveEaseOut, animations: { () -> Void in
self.label.center = self.view.center
}, completion: nil)
UIView.animateWithDuration(0.5, delay: 0.0, usingSpringWithDamping: 0.0, initialSpringVelocity: 0.0, options: .CurveEaseOut, animations: { () -> Void in
self.label.alpha = 0.0
}, completion: { finished in
self.poof.alpha = 1.0
dispatch_async(dispatch_get_main_queue(),{
self.performSegueWithIdentifier("backSegue", sender: nil)
})
})
}
}
Currently I am loading a new .Xib of class CreateAnAccount: UIView form a button pressed on another view.
At the moment it immediately switches to the Xib which is great, but is there a way of animating this? below is the code in the button.
#IBAction func createAnAccount(sender: AnyObject) {
let createAnAccountView = NSBundle.mainBundle().loadNibNamed("CreateAnAccount", owner: self, options: nil)[0] as! CreateAnAccount
createAnAccountView.frame = CGRectMake(0, 0, UIScreen.mainScreen().applicationFrame.size.width, UIScreen.mainScreen().applicationFrame.size.height + 20)
createAnAccountView.loginHandler = loginHandler
self.addSubview(createAnAccountView)
println("Create An Account Pressed")
}
Swift 4. Just place your animation code into layoutSubviews func. Works perfect for me.
override func layoutSubviews() {
super.layoutSubviews()
animate()
}
func animate() {
self.transform = CGAffineTransform(scaleX: 0.3, y: 2)
UIView.animate(withDuration: 1, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0, options: [.allowUserInteraction, .curveEaseOut], animations: {
self.transform = .identity
})
self.alpha = 1
}
Swift 5. #coldembrace answer
func animate() {
self.view.transform = CGAffineTransform(scaleX: 0.3, y: 2)
UIView.animate(withDuration: 1, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0, options: [.allowUserInteraction, .curveEaseOut], animations: {
self.view.transform = .identity
})
self.view.alpha = 1
}
You can try like this
UIView.transitionWithView(self.view, duration: 0.5, options:UIViewAnimationOptions.CurveEaseInOut,animations: {self.view.addSubview(createAnAccountView)}, completion: nil)
Moreover you change the UIViewAnimationOptions to have a desired effect.

I'm trying to do scale animation for UIButton when its clicked but what I'm trying to accomplish is when the button clicked I need the UIButton to be smaller to the inside then it comes back to its same size (like a bubble).
I tried the following:
button.transform = CGAffineTransformMakeScale(-1, 1)
UIView.animateWithDuration(0.5, animations: { () -> Void in
button.transform = CGAffineTransformMakeScale(1,1)
})
Try this
UIView.animate(withDuration: 0.6,
animations: {
self.button.transform = CGAffineTransform(scaleX: 0.6, y: 0.6)
},
completion: { _ in
UIView.animate(withDuration: 0.6) {
self.button.transform = CGAffineTransform.identity
}
})
SWIFT 5 Code Update :I have animated button with a nice bouncing effect , with spring animation.
#IBOutlet weak var button: UIButton!
#IBAction func animateButton(sender: UIButton) {
sender.transform = CGAffineTransform(scaleX: 0.6, y: 0.6)
UIView.animate(withDuration: 2.0,
delay: 0,
usingSpringWithDamping: CGFloat(0.20),
initialSpringVelocity: CGFloat(6.0),
options: UIView.AnimationOptions.allowUserInteraction,
animations: {
sender.transform = CGAffineTransform.identity
},
completion: { Void in() }
)
}
All of the answers above are valid.
As a plus, with Swift I suggest to create an extension of UIView in order to "scale" any view you want.
You can take inspiration from this piece of code:
SWIFT 5.0
extension UIView {
/**
Simply zooming in of a view: set view scale to 0 and zoom to Identity on 'duration' time interval.
- parameter duration: animation duration
*/
func zoomIn(duration: TimeInterval = 0.2) {
self.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
UIView.animate(withDuration: duration, delay: 0.0, options: [.curveLinear], animations: { () -> Void in
self.transform = .identity
}) { (animationCompleted: Bool) -> Void in
}
}
/**
Simply zooming out of a view: set view scale to Identity and zoom out to 0 on 'duration' time interval.
- parameter duration: animation duration
*/
func zoomOut(duration : TimeInterval = 0.2) {
self.transform = .identity
UIView.animate(withDuration: duration, delay: 0.0, options: [.curveLinear], animations: { () -> Void in
self.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
}) { (animationCompleted: Bool) -> Void in
}
}
/**
Zoom in any view with specified offset magnification.
- parameter duration: animation duration.
- parameter easingOffset: easing offset.
*/
func zoomInWithEasing(duration: TimeInterval = 0.2, easingOffset: CGFloat = 0.2) {
let easeScale = 1.0 + easingOffset
let easingDuration = TimeInterval(easingOffset) * duration / TimeInterval(easeScale)
let scalingDuration = duration - easingDuration
UIView.animate(withDuration: scalingDuration, delay: 0.0, options: .curveEaseIn, animations: { () -> Void in
self.transform = CGAffineTransform(scaleX: easeScale, y: easeScale)
}, completion: { (completed: Bool) -> Void in
UIView.animate(withDuration: easingDuration, delay: 0.0, options: .curveEaseOut, animations: { () -> Void in
self.transform = .identity
}, completion: { (completed: Bool) -> Void in
})
})
}
/**
Zoom out any view with specified offset magnification.
- parameter duration: animation duration.
- parameter easingOffset: easing offset.
*/
func zoomOutWithEasing(duration: TimeInterval = 0.2, easingOffset: CGFloat = 0.2) {
let easeScale = 1.0 + easingOffset
let easingDuration = TimeInterval(easingOffset) * duration / TimeInterval(easeScale)
let scalingDuration = duration - easingDuration
UIView.animate(withDuration: easingDuration, delay: 0.0, options: .curveEaseOut, animations: { () -> Void in
self.transform = CGAffineTransform(scaleX: easeScale, y: easeScale)
}, completion: { (completed: Bool) -> Void in
UIView.animate(withDuration: scalingDuration, delay: 0.0, options: .curveEaseOut, animations: { () -> Void in
self.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
}, completion: { (completed: Bool) -> Void in
})
})
}
}
Usage is very simply:
let button = UIButton(frame: frame)
button.zoomIn() // here the magic
Swift 3 Version
extension UIView {
/**

func zoomIn(duration: TimeInterval = 0.2) {

UIView.animate(withDuration: duration, delay: 0.0, options: [.curveLinear], animations: { () -> Void in
self.transform = CGAffineTransform.identity
}) { (animationCompleted: Bool) -> Void in
}
}

let easeScale = 1.0 + easingOffset
let easingDuration = TimeInterval(easingOffset) * duration / TimeInterval(easeScale)
let scalingDuration = duration - easingDuration
UIView.animate(withDuration: scalingDuration, delay: 0.0, options: .curveEaseIn, animations: { () -> Void in

}, completion: { (completed: Bool) -> Void in
UIView.animate(withDuration: easingDuration, delay: 0.0, options: .curveEaseOut, animations: { () -> Void in

})
})
}

*/
func zoomOutWithEasing(duration: TimeInterval = 0.2, easingOffset: CGFloat = 0.2) {
let easeScale = 1.0 + easingOffset
let easingDuration = TimeInterval(easingOffset) * duration / TimeInterval(easeScale)

})
}
}
Swift 3.x+
extension UIButton {
func pulsate() {
let pulse = CASpringAnimation(keyPath: "transform.scale")
pulse.duration = 0.2
pulse.fromValue = 0.95
pulse.toValue = 1.0
pulse.autoreverses = true
pulse.repeatCount = 2
pulse.initialVelocity = 0.5
pulse.damping = 1.0
layer.add(pulse, forKey: "pulse")
}
func flash() {
let flash = CABasicAnimation(keyPath: "opacity")
flash.duration = 0.2
flash.fromValue = 1
flash.toValue = 0.1
flash.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
flash.autoreverses = true
flash.repeatCount = 3
layer.add(flash, forKey: nil)
}
func shake() {
let shake = CABasicAnimation(keyPath: "position")
shake.duration = 0.05
shake.repeatCount = 2
shake.autoreverses = true
let fromPoint = CGPoint(x: center.x - 5, y: center.y)
let fromValue = NSValue(cgPoint: fromPoint)
let toPoint = CGPoint(x: center.x + 5, y: center.y)
let toValue = NSValue(cgPoint: toPoint)
shake.fromValue = fromValue
shake.toValue = toValue
layer.add(shake, forKey: "position")
}
}
Usage:
myButton.flash()
// myButton.pulsate()
// myButton.shake()

Swift 3 Version:
UIView.animate(withDuration: 0.6, animations: {
button.transform = CGAffineTransform.identity.scaledBy(x: 0.6, y: 0.6)
}, completion: { (finish) in
UIView.animate(withDuration: 0.6, animations: {
button.transform = CGAffineTransform.identity
})
})
Using Swift 4 Xcode 9, This will animate the button down when initially pressed and then back up when released.
extension UIView {
func animateButtonDown() {
UIView.animate(withDuration: 0.1, delay: 0.0, options: [.allowUserInteraction, .curveEaseIn], animations: {
self.transform = CGAffineTransform(scaleX: 0.9, y: 0.9)
}, completion: nil)
}
func animateButtonUp() {
UIView.animate(withDuration: 0.1, delay: 0.0, options: [.allowUserInteraction, .curveEaseOut], animations: {
self.transform = CGAffineTransform.identity
}, completion: nil)
}
Implementation:
#IBAction func buttonTouchDown(_ sender: UIButton) {
//Connected with Touch Down Action
sender.animateButtonDown()
}
#IBAction func buttonTouchUpOutside(_ sender: UIButton) {
//Connected with Touch Up Outside Action
//if touch moved away from button
sender.animateButtonUp()
}
#IBAction func buttonTouchUpInside(_ sender: UIButton) {
//Connected with Touch Up Inside Action
sender.animateButtonUp()
//code to execute when button pressed
}
It works with me as following, the animation is set to be small then when it start animation it get back to its original size:
Swift 2
button.transform = CGAffineTransformMakeScale(0.6, 0.6)
UIView.animateWithDuration(0.3, animations: { () -> Void in
button.transform = CGAffineTransformMakeScale(1,1)
})
Swift 3, 4, 5
button.transform = CGAffineTransform.init(scaleX: 0.6, y: 0.6)
UIView.animate(withDuration: 0.3, animations: { () -> Void in
button.transform = CGAffineTransform.init(scaleX: 1, y: 1)
})
I prefer to have the press animation and set it more fast than the other examples, with the completion control for waiting until the animation is ended:
Swift 3:
extension UIButton {
func press(completion:#escaping ((Bool) -> Void)) {
UIView.animate(withDuration: 0.05, animations: {
self.transform = CGAffineTransform(scaleX: 0.8, y: 0.8) }, completion: { (finish: Bool) in
UIView.animate(withDuration: 0.1, animations: {
self.transform = CGAffineTransform.identity
completion(finish)
})
})
}
}
Usage:
#IBAction func playPauseBtnTap(_ sender: Any) {
let playPauseBtn = sender as! UIButton
playPauseBtn.press(completion:{ finish in
if finish {
print("animation ended")
}
}
}
Using the following animation the button will start from its full size, decrease to 0.6 with a spring animation to bounce back to it's full size.
[UIView animateWithDuration:0.5 delay:0 usingSpringWithDamping:0.4 initialSpringVelocity:0.3 options:0 animations:^{
//Animations
button.transform = CGAffineTransformIdentity;
CGAffineTransformMakeScale(0.6, 0.6)
} completion:^(BOOL finished) {
//Completion Block
[UIView.animateWithDuration(0.5){
button.transform = CGAffineTransformIdentity
}];
}];
You can try this if you want a Autoreverse effect with a completion handler.
viewToAnimate.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
UIView.animate(withDuration: 0.7, // your duration
delay: 0,
usingSpringWithDamping: 0.2,
initialSpringVelocity: 6.0,
animations: { _ in
viewToAnimate.transform = .identity
},
completion: { _ in
// Implement your awesome logic here.
})
iOS 9 and xCode 7
//for zoom in
[UIView animateWithDuration:0.5f animations:^{
self.sendButton.transform = CGAffineTransformMakeScale(1.5, 1.5);
} completion:^(BOOL finished){}];
// for zoom out
[UIView animateWithDuration:0.5f animations:^{
self.sendButton.transform = CGAffineTransformMakeScale(1, 1);
}completion:^(BOOL finished){}];
This will give a wonderful bouncing effect:
#IBAction func TouchUpInsideEvent(sender: UIButton) {
UIView.animateWithDuration(2.0,
delay: 0,
usingSpringWithDamping: CGFloat(0.20),
initialSpringVelocity: CGFloat(6.0),
options: UIViewAnimationOptions.AllowUserInteraction,
animations: {
sender.transform = CGAffineTransformIdentity
},
completion: { Void in() }
)
}
#IBAction func touchDownEvent(sender: UIButton) {
UIView.animateWithDuration(0.15, animations: {
sender.transform = CGAffineTransformMakeScale(0.6, 0.6)
})
}
Scaling Button or any view about three times or more use following code. swift 3 or swift 4 with xcode 9.
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
}, completion: { (finish: Bool) in
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform.identity
}, completion:{(finish: Bool) in
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
}, completion: { (finish: Bool) in
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform.identity
}, completion:{(finish: Bool) in
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
}, completion: { (finish: Bool) in
UIView.animate(withDuration: 0.2, animations: {
self.cartShowHideBtnView.transform = CGAffineTransform.identity
})
})
})
})
})
})
I did a protocol using Swift 4, that you can use at some specifics UIViews that you want to animate... You can try some animations over here or change time and delay.
This way is recommended because you can use this protocol and others at one view and this view can use this functions, doing a lot os extensions from UIView create code smell.
import Foundation
import UIKit
protocol Showable where Self: UIView {}
extension Showable {
func show(_ view: UIView? = nil) {
if let view = view {
self.animate(view)
} else {
self.animate(self)
}
}
private func animate(_ view: UIView) {
view.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
UIView.animate(withDuration: 2.0,
delay: 0,
usingSpringWithDamping: CGFloat(0.20),
initialSpringVelocity: CGFloat(6.0),
options: [.allowUserInteraction],
animations: {
view.transform = CGAffineTransform.identity
})
}
}
Here is a working example :
extension UIButton{
func flash() {
let flash = CABasicAnimation(keyPath: "opacity")
flash.duration = 0.5
flash.fromValue = 1
flash.toValue = 0.1
flash.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
flash.autoreverses = true
flash.repeatCount = 3
layer.add(flash, forKey: nil)
}
}
#IBAction func taptosave(_ sender: UIButton) {
sender.flash()
}
