removeConstraint(_:)
Removes the specified constraint from the view.
Declaration
func removeConstraint(_ constraint: NSLayoutConstraint)Parameters
- constraint:
The constraint to remove. Removing a constraint not held by the view has no effect.
Discussion
When developing for iOS 8.0 or later, set the constraint’s isActive property to false instead of calling the removeConstraint(_:) method directly. The isActive property automatically adds and removes the constraint from the correct view.
