Type Method

activate(_:)

Activates each constraint in the specified array.

Declaration

class func activate(_ constraints: [NSLayoutConstraint])

Parameters

constraints

An array of constraints to activate.

Discussion

This convenience method provides an easy way to activate a set of constraints with one call. The effect of this method is the same as setting the isActive property of each constraint to true. Typically, using this method is more efficient than activating each constraint individually.
