StackScrollView

<img width=320 src="Resources/shot.png"><img width=320 src="Resources/sample.gif">

⚠️ This sample is using demo-components. StackScrollView does not have default-components. StackScrollView is like UIStackView. So, we need to create the components we need.

What is this?

StackScrollView builds form UI easily.

StackScrollView includes UICollectionView. UICollectionView calculates size of view by AutoLayout, then that display. (Use systemLayoutSizeFitting)

• We call StackCell instead of Cell on StackScrollView.
• We no longer need to consider reusing Cells.
• StackCell requires constraint based layout.

Usage

Basic usage

let stack = StackScrollView()

stack.append(view: ...)

stack.remove(view: ..., animated: true)

APIs

StackScrollView

func append(view: UIView)
func remove(view: UIView, animated: Bool)
func scroll(to view: UIView, at position: UICollectionViewScrollPosition, animated: Bool)

StackCellType

StackScrollView does not required StackCellType. if StackCell has StackCellType, be easy that control StackCell.

func scrollToSelf(animated: Bool)
func scrollToSelf(at position: UICollectionViewScrollPosition, animated: Bool)
func updateLayout(animated: Bool)
func remove()

Demo has included this APIs usage.

Create CustomCell from Code

We have to set constraints completely.

final class LabelStackCell: UIView {
  
  private let label = UILabel()
  
  init(title: String) {
    super.init(frame: .zero)
    
    addSubview(label)
    label.translatesAutoresizingMaskIntoConstraints = false
    
    label.topAnchor.constraint(greaterThanOrEqualTo: topAnchor, constant: 8).isActive = true
    label.bottomAnchor.constraint(lessThanOrEqualTo: bottomAnchor, constant: 8).isActive = true
    label.rightAnchor.constraint(equalTo: rightAnchor, constant: 8).isActive = true
    label.leftAnchor.constraint(equalTo: leftAnchor, constant: 8).isActive = true
    label.centerYAnchor.constraint(equalTo: centerYAnchor).isActive = true
    heightAnchor.constraint(greaterThanOrEqualToConstant: 40).isActive = true
    
    label.font = UIFont.preferredFont(forTextStyle: .body)
    label.text = title
  }
}

let stack = StackScrollView()
stack.append(view: LabelStackCell(title: "Label"))

Create CustomCell from XIB

We can use UIView from XIB.

This framework has NibLoader<T: UIView>. It might be useful for you.

Create everything

You can create any Cell. Please, check StackScrollView-Demo

ManualLayout

You can create Cell with ManualLayout.

If you use ManualLayout, the Cell have to use ManualLayoutStackCellType. Then, return self-size based on maximum size in size(maxWidth:maxHeight)
