UIView anchor isActive option

[sbrioux]

Was wondering about possibly modifying the anchor method to have an additional property at the end. Add in a isActive: Bool = true. That way we can make multiple sets of constraints and activate and deactivate as needed.

Example would be a set of default constraints and a set of constraints for Accessibility text sizes.

Like this:

    @discardableResult
    open func anchor(top: NSLayoutYAxisAnchor?, leading: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, trailing: NSLayoutXAxisAnchor?, padding: UIEdgeInsets = .zero, size: CGSize = .zero, isActive: Bool = true) -> AnchoredConstraints {
        
        translatesAutoresizingMaskIntoConstraints = false
        var anchoredConstraints = AnchoredConstraints()
        
        if let top = top {
            anchoredConstraints.top = topAnchor.constraint(equalTo: top, constant: padding.top)
        }
        
        if let leading = leading {
            anchoredConstraints.leading = leadingAnchor.constraint(equalTo: leading, constant: padding.left)
        }
        
        if let bottom = bottom {
            anchoredConstraints.bottom = bottomAnchor.constraint(equalTo: bottom, constant: -padding.bottom)
        }
        
        if let trailing = trailing {
            anchoredConstraints.trailing = trailingAnchor.constraint(equalTo: trailing, constant: -padding.right)
        }
        
        if size.width != 0 {
            anchoredConstraints.width = widthAnchor.constraint(equalToConstant: size.width)
        }
        
        if size.height != 0 {
            anchoredConstraints.height = heightAnchor.constraint(equalToConstant: size.height)
        }
        
        [anchoredConstraints.top, anchoredConstraints.leading, anchoredConstraints.bottom, anchoredConstraints.trailing, anchoredConstraints.width, anchoredConstraints.height].forEach{ $0?.isActive = isActive }
        
        return anchoredConstraints
    }

This functionality falls outside the scope of this library. You can include your own extension that can disable all the AnchorConstraints [.top, .bottom, .trailing, .leading, .height, .width] constraints.
