Type Property

fittingSizeLevel

The priority level with which the view wants to conform to the target size in that computation.

Declaration

static let fittingSizeLevel: UILayoutPriority

Discussion

When you send a systemLayoutSizeFitting(_:) message to a view, the size fitting most closely to the target size is computed. This priority is quite low. It is generally not appropriate to make a constraint at exactly this priority. You want to be higher or lower.

var priority: UILayoutPriority

The priority of the constraint.

struct UILayoutPriority

The layout priority is used to indicate to the constraint-based layout system which constraints are more important, allowing the system to make appropriate tradeoffs when satisfying the constraints of the system as a whole.

static let defaultHigh: UILayoutPriority

The priority level with which a button resists compressing its content.

static let defaultLow: UILayoutPriority

The priority level at which a button hugs its contents horizontally.

struct NSLayoutConstraint.Priority

Layout priority used to indicate the relative importance of constraints, allowing Auto Layout to make appropriate tradeoffs when satisfying the constraints of the system as a whole.
