Overview​

The LMStackView is a customizable stack view widget that extends UIStackView with additional functionality for layout management and subview handling. It provides convenient methods for managing arranged subviews and Auto Layout constraints.

File Location:
LMStackView.swift

Functionality​

UI Components​

  • arrangedSubviews: The array of views arranged by the stack view
  • axis: The axis along which the arranged views are laid out
  • distribution: The distribution of the arranged views along the stack view's axis
  • alignment: The alignment of the arranged views perpendicular to the stack view's axis
  • spacing: The distance between adjacent arranged views

Methods​

  • init(frame:): Initializes the stack view with a frame
  • translatesAutoresizingMaskIntoConstraints() -> Self: Disables autoresizing mask translation and returns self for chaining
  • removeAllArrangedSubviews(): Removes all arranged subviews and deactivates their constraints

Customization​

CustomLMStackView.swift
class CustomLMStackView: LMStackView {
    override init(frame: CGRect) {
        super.init(frame: frame)

        setupDefaultAppearance()
    }
    
    private func setupDefaultAppearance() {
        axis = .vertical
        distribution = .fill
        alignment = .fill
        spacing = 8
        backgroundColor = .clear
    }
    
    override func removeAllArrangedSubviews() {
        super.removeAllArrangedSubviews()
        // Add custom cleanup behavior
    }
}
