I am currently working on an animation for my ios application. When it gets triggered three blocks (UIView with borders) move down and a new block comes in from the left.

It works perfectly until I change the text of the label (Block Number) before the animation starts. The blocks spawn in completely different positions and move back to the start position. They also change their order.

The following code shows my block class. For the animation I use the getBlockView and "view.frame = GCRect(...)". For changing the label text I use the setBlockName(number: String) function.

At the moment I don´t have any idea what could cause that and would be thankful for every suggestion what could cause this weird behaviour.

class myBlock 
 var positionID: Int
 var blockNumber: String
 let blockView: UIView
 let blockNumberLabel: UILabel

 init(blockNumber: String, heightScreen: CGFloat, widthScreen: CGFloat, positionID: Int) 
 self.positionID = positionID
 self.blockNumber = blockNumber
 blockView = 
 let view = UIView()
 view.autoSetDimension(.height, toSize: heightScreen / 6)
 view.autoSetDimension(.width, toSize: widthScreen - 80)
 view.layer.borderWidth = 3
 view.layer.borderColor = UIColor.MyTheme.primaryColor1.cgColor
 return view
 ()
 blockNumberLabel = 
 let label = UILabel()
 label.textColor = UIColor.MyTheme.primaryColor1
 label.font = UIFont(name: "ArialMT", size: 20)
 label.numberOfLines = 2
 label.textAlignment = .left
 label.adjustsFontForContentSizeCategory = true
 label.text = "Block Number: (blockNumber)"
 label.isUserInteractionEnabled = false
 return label
 ()

 blockView.addSubview(blockNumberLabel)
 blockNumberLabel.autoPinEdge(toSuperviewEdge: .top, withInset: 5.0)
 blockNumberLabel.autoPinEdge(toSuperviewEdge: .left, withInset: 5.0)
 blockNumberLabel.autoPinEdge(toSuperviewEdge: .right, withInset: 5.0)

 

 func getBlockView() -> UIView
 return blockView
 

 func setBlockName(number: String) 
 self.blockNumberLabel.text = "Block Number: (number)"
 

 func getBlockLabel() -> UILabel
 return blockNumberLabel
 

 func getID() -> Int 
 return positionID
 

 func setID(id: Int) 
 self.positionID = id
 print("(blockNumberLabel.text!): (id)")
 

 

Animation Code:

 private func moveBlocksDown(blockNumber: String) 
 var resetBlock: UIView!
 let animationHeight = (self.heightScreen / 6) + (self.blockDistance)



 UIView.animate(withDuration: 2.0, animations: 
 for var block in self.blockList 
 let id = block.getID()
 let blockView = block.getBlockView()
 if block.getID() == 0 
 block.setBlockName(number: blockNumber)
 
 print(id)
 switch id 
 case 0:
 blockView.frame = CGRect(x: self.topX, y: self.topY, width: blockView.frame.width, height: blockView.frame.height)
 print(block.getBlockLabel().text!)
 case 1:
 blockView.frame = CGRect(x: self.topX, y: self.middleY, width: blockView.frame.width, height: blockView.frame.height)
 print(block.getBlockLabel().text!)
 case 2:
 blockView.frame = CGRect(x: self.topX, y: self.bottomY, width: blockView.frame.width, height: blockView.frame.height)
 print(block.getBlockLabel().text!)
 case 3:
 blockView.frame = CGRect(x: self.topX, y: (self.bottomY + animationHeight), width: blockView.frame.width, height: blockView.frame.height)
 print(block.getBlockLabel().text!)
 resetBlock = blockView
 default:
 print("Unknown ID")
 
 print("NewID ((id + 1) % 4)")
 block.setID(id: (id + 1) % 4)
 
 , completion: finish in 
 resetBlock.frame = CGRect(x: self.newX, y: self.newY, width: resetBlock.frame.width, height: resetBlock.frame.height)
