MiniLayout

Minimal AutoLayout convenience layer. Program constraints succinctly.

Usage

Put label over textField

// using MiniLayout: view.constrain(label, at: .leading, to: textField) view.constrain(textField, at: .top, to: label, at: .bottom, diff: 8)

// without MiniLayout: view.addConstraint( NSLayoutConstraint(item: label, attribute: .leading, relatedBy: .equal, toItem: textField, attribute: .leading, multiplier: 1, constant: 0) ) view.addConstraint( NSLayoutConstraint(item: textField, attribute: .top, relatedBy: .equal, toItem: label, attribute: .bottom, multiplier: 1, constant: 8) )

Add button at the center of view

// using MiniLayout: view.addConstrainedSubview(button, constrain: .centerX, .centerY)

// without MiniLayout: view.addSubview(button) button.setTranslatesAutoresizingMaskIntoConstraints(false) view.addConstraint( NSLayoutConstraint(item: button, attribute: .centerX, relatedBy: .equal, toItem: view, attribute: .centerX, multiplier: 1, constant: 0) ) view.addConstraint( NSLayoutConstraint(item: button, attribute: .centerY, relatedBy: .equal, toItem: view, attribute: .centerY, multiplier: 1, constant: 0) )

Add child view controller covering all but the bottom margin

// using MiniLayout: addConstrainedChild(vc, constrain: .bottomMargin, .top, .left, .right)

// without MiniLayout: addChild(vc) view.addSubview(vc.view) vc.view.setTranslatesAutoresizingMaskIntoConstraints(false) view.addConstraint( NSLayoutConstraint(item: vc.view, attribute: .bottomMargin, relatedBy: .equal, toItem: view, attribute: .bottomMargin, multiplier: 1, constant: 0) ) view.addConstraint( NSLayoutConstraint(item: vc.view, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1, constant: 0) ) view.addConstraint( NSLayoutConstraint(item: vc.view, attribute: .left, relatedBy: .equal, toItem: view, attribute: .left, multiplier: 1, constant: 0) ) view.addConstraint( NSLayoutConstraint(item: vc.view, attribute: .right, relatedBy: .equal, toItem: view, attribute: .right, multiplier: 1, constant: 0) ) vc.didMove(toParent: self)
