I'm trying to add Swipe to right and left to collection view cell to transform the container to the right and left with a certain angle
Here is my initial setup
private func setupGestures() {
let swipeToRight = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeRight))
swipeToRight.direction = .right
container.addGestureRecognizer(swipeToRight)
let swipeToLeft = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeLeft))
swipeToLeft.direction = .left
container.addGestureRecognizer(swipeToLeft)
}
@objc func respondToSwipeRight(gesture: UIGestureRecognizer) {
let angle = CGFloat(Double.pi/2)
UIView.animate(withDuration: 0.5) {
self.container.transform = CGAffineTransform(rotationAngle: angle)
}
}
@objc func respondToSwipeLeft(gesture: UIGestureRecognizer) {
let angle = -CGFloat(Double.pi/2)
UIView.animate(withDuration: 0.5) {
self.container.transform = CGAffineTransform(rotationAngle: angle)
}
}
But it completely rotate the container, which is I don't want, I want to make it something like it, and turn back to it's initial position after a sec or two
[![how it should transform][1]][1]
And it would be so awesome that move based on Swiping position, I mean not automatically goes to that level of position, move with finger tip and when it reach there, just stop moving.
Could anyone help me to implement it, I have no idea how I can do it
Many thanks
Adding completion
in UIView.animate
in order to turn back to initial state. After a sec or two is depends on your duration
in UIView.animate
Code will be like this
UIView.animate(withDuration: 0.5, animations: {
self.container.transform = CGAffineTransform(rotationAngle: 0.5)
}, completion: {
_ in
// turn back to the previous before transform
self.container.transform = .identity
})
And for your second question, you can implement with touchesBegan
and touchesMoved
or add PanGesture
to handle changing position container view frame like you want.
