This repository provides some convenience methods for creating constraints.
- Pin attributes of the view to a specified item or its superview.
view.pin(.edges)
view.pin(.leading)
view.pin(.edges(.horizontal), 16)
view.pin(edges(.top, .bottom), 10, to: safeAreaLayoutGuide)
view.pin(edges: [.top: 10, .horizontal: 5], to: safeAreaLayoutGuide)
// pin view after/before another view
rightView.pin(to: .trailing, of: leftView, options: .offset(10))
view.pin(.center, 10)
view.pin([.size: 100, .centerY: 10, .top: 20, .edges(.horizontal): 10])- Pin any attributes between two views
view.pin(.top, to: .centerY, of: anotherView)- Set aspect ratio of the view.
view.pin(aspectRatio: 2 / 3)- All pin methods contain a
with optionsparameter.
view.pin(.edges, 10, options: .priority(.required))options:
.priority(300): set the priority of the constraint.offset(10): set the offset of the constraint.multiplier(2): set the multiplier of the constraint.relation(.greaterThanOrEqual),.greaterThanOrEqual,.lessThanOrEqual: set the relation of the constraint.inactive,.activated(false): set the active state of the constraint.update: update the constraint if it already exists.translatesAutoresizingMask: don't changetranslatesAutoresizingMaskIntoConstraintsproperty.safeArea: usesafeAreaLayoutGuideinstead ofsuperviewas default second item
- All these methods can be chained
view
.pin(.edges(.horizontal), 10)
.pin(to: .bottom, of: anotherView.pin(.height, 50), options: .offset(20))
.pin(.size, 100)- Use
PartialRangeThroughandPartialRangeFromfor offset value
view.pin(.bottom, 10..., with: .safeArea)
view.pin(to: .bottom, of: anotherView, options: .offset(...10))- All these methods return
Constraintsobject, that can be used for updating constraints.
