We have enabled landscape mode but image seems to be glitched then used in landscape mode? Is it just to ensure the autolayout part and in partical scenarios we would disable the capability or is there any hack to this problem, Like adding some scroll element or some resizing of imageview ?

Great suff , Thanks Brian. I was wondering Do you have any course that covers real time app Unit Testing. I would love to purchase that course.

This episode was even better!

Loved the challenge. Great idea to implement this

Hi Brian, Here is my idea for the challenge fileprivate func handleGestureEnded(_ gesture: UIPanGestureRecognizer) { var shouldDismissCard = false let velocity = gesture.velocity(in: self) var direction: SwipeDirection = .right if velocity.x > 0 { direction = .right shouldDismissCard = gesture.translation(in: nil).x > threshold }else if (velocity.x < 0){ direction = .left shouldDismissCard = gesture.translation(in: nil).x < threshold } UIView.animate(withDuration: 0.75, delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 0.1, options: .curveEaseOut, animations: { if shouldDismissCard { self.frame = CGRect(x: CGFloat(direction.rawValue) * 1000, y: 0, width: self.frame.width, height: self.frame.height) }else { self.transform = .identity } }) { (_) in self.transform = .identity self.frame = CGRect(x: 0, y: 0, width: self.superview!.frame.width, height: self.superview!.frame.height) } } enum SwipeDirection: Int { case left = -1 case right = 1 case down = -2 case up = 2 }

This is the best $80 ive ever spent. Nice work ma dood!

Hi Brian, i have a problem when i move the card and the card come back is not back to the center, always show half on the screen i don't know why my code is same as your or even use your project always have this problem can you help me to figure out thanks

为什么我的项目中并没出现 “拖拽时卡片会跳动的bug”

Hi Brian, I have a question, when I run the app on an emulator the bottom icons look good but when I run it on my phone, the big icons look a bit streched, is there a way to format the codes in order to make them render less "streched"? Thanks in advance

let translation = gesture.translation(in: nil) let shouldDismissCard = translation.x > threshold || translation.x < -threshold UIView.animate(withDuration: 0.75, delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 0.1, options: .curveEaseOut, animations: { if shouldDismissCard { // // if translation.x > self.threshold { self.frame = CGRect(x: 1000, y: 0, width: self.frame.width, height: self.frame.height) }else if translation.x < -self.threshold { self.frame = CGRect(x: -1000, y: 0, width: self.frame.width, height: self.frame.height) } // let offScreenTransform = self.transform.translatedBy(x: 1000, y: 0) // self.transform = offScreenTransform }else { self.transform = .identity } }) { (_) in self.transform = .identity self.frame = CGRect(x: 0, y: 0, width: self.superview!.frame.width, height: self.superview!.frame.height) }

Hi Brian, I have found a bug and am not sure why it is happening. The card when animated off the screen doesn't fully animate off of the screen with the newest version of Xcode 11 and iOS 13. Instead it of translating off of the screen it moves to the right half of the screen and stays there. I have also downloaded your project and without making any modifications to your project I still had the same issue. On a separate note, in my version, I wanted to add the feature that changes the rotation angle to be positive or negative based on where the touch began on the card. So if the card is translated when tapped and dragged from the top the rotation angle would be positive and if it was tapped and dragged from the bottom half of the card the rotation angle would be negative. I am curious to know if the code I added would do the job correctly and wanted to know if you knew a cleaner and better solution. And again, just for clarification my code below was not inserted when I encountered the off screen translation issue. Thanks in advance and love these tutorials. // Added this to the configurations at the top of the file var rotateUpDown = 0 // Added this override function just above the handleChanged function override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { if let touch = touches.first { let position = touch.location(in: imageView) if position.y > 374.5 { rotateUpDown = -1 } else { rotateUpDown = 1 } } } // Lastly, I modified the angle in handleChanged() to account for the rotate angle change let angle = (degrees * .pi / 180) * CGFloat(rotateUpDown)

I found a solution to the cardview animation error in ios 13 version. See the code below. :) fileprivate func handleEnded(_ gesture: UIPanGestureRecognizer) { // determine dismiss card or not let translationDirection: CGFloat = gesture.translation(in: nil).x > 0 ? 1 : -1 let shouldDismissCard = abs(gesture.translation(in: nil).x) > threshold UIView.animate(withDuration: 0.75, delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 0.1, options: .curveEaseOut, animations: { if shouldDismissCard { // self.frame = CGRect(x: 0, // y: 0, // width: self.frame.width, // height: self.frame.height) self.center = CGPoint(x: 1000 * translationDirection, y: 0) } else { self.transform = .identity } }) { (_) in self.transform = .identity self.frame = CGRect(x: 0, y: 0, width: self.superview!.frame.width, height: self.superview!.frame.height) } }
