How can I create such animations or custom transitions in scroll view. You can see the expected animation in the GIF : https://gfycat.com/EveryBackLhasaapso
Expecting:
On longpress over the scrollview, it needs to get expand like the gif animation and the icon also need to get zoomin.
I have tried to attain this using a scrollview, but the animation doesn't matches as expected.
UIView.animate(withDuration: 0.2, delay: 0.2, usingSpringWithDamping: 0.5, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
self.scrollViewHeight.constant = isExpanded == true ? ViewConstants.collectionViewHeightWithExpand : ViewConstants.collectionViewHeightWithcollapse
self.scrollContentViewHeight.constant = isExpanded == true ? ViewConstants.collectionViewHeightWithExpand : ViewConstants.collectionViewHeightWithcollapse
self.scrollContentView.transform = isExpanded == true ? CGAffineTransform(scaleX: 1.20, y: 1.20) : CGAffineTransform.identity
self.view.layoutIfNeeded()
}) { _ in}
Now run your application.
self.scrollViewHeight.constant = isExpanded == true ? ViewConstants.collectionViewHeightWithExpand : ViewConstants.collectionViewHeightWithcollapse
self.scrollContentViewHeight.constant = isExpanded == true ? ViewConstants.collectionViewHeightWithExpand : ViewConstants.collectionViewHeightWithcollapse
UIView.animate(withDuration: 0.2, delay: 0.2, usingSpringWithDamping: 0.5, initialSpringVelocity: 1, options: .curveEaseInOut, animations: {
self.scrollContentView.transform = isExpanded == true ? CGAffineTransform(scaleX: 1.20, y: 1.20) : CGAffineTransform.identity
self.view.layoutIfNeeded()
}) { _ in}

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,
usingSpringWithDamping: 0.6,

options: [], animations: {
self.containerDownloadButton.center.x += self.view.bounds.width
}, completion: nil)

}, completion: nil)
UIView.animate(withDuration: 1.5, delay: 0.9,
usingSpringWithDamping: 0.6,
initialSpringVelocity: 1,

self.containerIdleButton.center.x += self.view.bounds.width
}, completion: nil)
I am using TextFieldEffects to add text inputs effects in my textField. it is showing an error
Type 'UIView' has no member 'AnimationOptions'
Here's code.
override open func animateViewsForTextEntry() {
borderLayer.frame.origin = CGPoint(x: 0, y: font!.lineHeight)
UIView.animate(withDuration: 0.2, delay: 0.3, usingSpringWithDamping: 0.8, initialSpringVelocity: 1.0, options: UIView.AnimationOptions.beginFromCurrentState, animations: ({
self.placeholderLabel.frame.origin = CGPoint(x: self.placeholderInsets.x, y: self.borderLayer.frame.origin.y - self.placeholderLabel.bounds.height)
self.borderLayer.frame = self.rectForBorder(self.borderThickness, isFilled: true)
}), completion: { _ in
self.animationCompletionHandler?(.textEntry)
})
}
override open func animateViewsForTextDisplay() {
if text!.isEmpty {
UIView.animate(withDuration: 0.35, delay: 0.0, usingSpringWithDamping: 0.8, initialSpringVelocity: 2.0, options: UIView.AnimationOptions.beginFromCurrentState, animations: ({
self.layoutPlaceholderInTextRect()
self.placeholderLabel.alpha = 1
}), completion: { _ in
self.animationCompletionHandler?(.textDisplay)
})
borderLayer.frame = rectForBorder(borderThickness, isFilled: false)
}
}
Here's a screenshot of the error.
How to solve this issue?
It should be UIViewAnimationOptions.beginFromCurrentState, at least in Xcode < version 10.
Try changing UIView.AnimationOptions.beginFromCurrentState to [.beginFromCurrentState].
I am learning swift, I was successfully able to do popup animation of an UIView as below code but now i want to do reverse of it. i.e the way the UIView was animated should go back on a button click, Like the view is shrinking and then disappears.
popupView.isHidden = false
popupInnerView.isHidden = false
popupInnerView.transform = CGAffineTransform(scaleX: 0, y: 0)
UIView.animate(withDuration: 1, delay: 0, options: .curveLinear, animations: {
self.popupView.alpha = 1.0;
self.popupInnerView.transform = .identity
}, completion: nil)
Check if this one works for you. I have bound the showing and hiding of popup to buttons but you can bind them to anything.
For this to work
Drag and drop a uiview(your popup) into dock of view controller (see picture)
Make outlet of your uiview(popup) in your view controller. I am calling it popupView
For showing popup with Animation use the code
#IBAction func btnShowPopupTapped(_ sender: UIButton) {
popupView.center = view.center
popupView.alpha = 1
popupView.transform = CGAffineTransform(scaleX: 0.8, y: 1.2)
self.view.addSubview(popupView)
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 0, options: [], animations: {
//use if you want to darken the background
//self.viewDim.alpha = 0.8
//go back to original form
self.popupView.transform = .identity
})
}
And for hiding the popup
#IBAction func btnHideMeTapped(_ sender: Any) {
UIView.animate(withDuration: 0.3, delay: 0, usingSpringWithDamping: 0.5, initialSpringVelocity: 0, options: [], animations: {
//use if you wish to darken the background
//self.viewDim.alpha = 0
self.popupView.transform = CGAffineTransform(scaleX: 0.2, y: 0.2)
}) { (success) in
self.popupView.removeFromSuperview()
}
}
Note: If you want to darken the background as in gif.
Drag and drop a uiview into your view heirarchy (view dim). see the pic
pin to 0, 0 , 0 ,0 to the main view
set its background color to black
set is alpha to 0
uncomment the line (self.viewDim.alpha = 0.8) in "btnShowPopupTapped" Action
uncomment the line (self.viewDim.alpha = 0) in "btnHideMeTapped" Action
Let me know if this helps.
Try This
For Zoom in
UIView.animate(withDuration: 1, delay: 0, options: .curveLinear, animations: {
self.popupInnerView.transform = CGAffineTransform(scaleX: 0.001, y: 0.001)
}, completion: { _ in
self.popupInnerView.transform = CGAffineTransform(scaleX: 0.0, y: 0.0)
})
For Zoom Out
UIView.animate(withDuration: 1, delay: 0, options: .curveLinear, animations: {
self.popupInnerView.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
}, completion: nil)
This code worked for Pop Out
UIView.animate(withDuration: 1, delay: 0, options: .curveLinear, animations: {
self.popupView.alpha = 0.0;
self.popupInnerView.transform = CGAffineTransform(scaleX: 0.1, y: 0.1)
}, completion: { _ in
self.popupView.isHidden = true
self.popupInnerView.isHidden = true
})
How can I create an animation like in the following link?

I'm using the below for animate cell from left in tableview delegate method willdisplaycell. Issue is all the cells are animating at a time not one after other, can anyone advice me how can I achieve that?
let direction:CGFloat = -1.0
cell?.layer.opacity = 0.4
cell?.transform = CGAffineTransform(translationX: (cell?.bounds.size.width)! * direction, y: 0)
UIView.animate(withDuration: 0.5, delay: 0, usingSpringWithDamping: 0.85, initialSpringVelocity: 0.8, options: [], animations: {
cell?.transform = CGAffineTransform.identity
cell?.contentView.layer.opacity = 1.0
}) { _ in
self.isForExpand = false
}
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.
