Fill views in iOS easy

JVConstraintEdges

Short introduction JVConstraintEdges makes it very easy to add views that are constrainted to other views. Along with extensions to UIView, adding views programmatically is fast and easy.

How to use

This section is split up in two sections:

1. The struct ConstraintEdges.
2. General extensions.

ConstraintEdges

ConstraintEdges is a struct with 4 properties: leading, top, trailing and bottom. It is very similar to UIRectInsets, however, all the properties of ConstraintEdges are optional. There are a lot of overloaded/convencience overloads available e.g.:

let edges = ConstraintEdges(all: 5) // Initializes all 4 properties with a value of 5 
let view = UIView() 
view.fill(toSuperview: mySuperview, edges: edges) * 

*-Omit the edges parameters to completetly fill the calling uiview to the superview. -Add toSafeEdges to the parameters to fill it to the safe areas.

General UIView extensions

The following extensions are pretty commonly used:

• Filling a view. fill(toSuperview: UIView,
  edges: ConstraintEdges? = nil,
  addToSuperView: Bool = true,
  toSafeMargins: Bool = false) This method is also seen in section ConstraintEdges.

• Filling a view with a callback to the (added) constraints fillWithResult(… activateConstraints: Bool = true) Fill with result does do the same thing as the normal fill function, but it returns the constraints it has added.

• Set equal height/width to other UIView .equal(to: UIView, height: Bool, width: Bool) The function signature is pretty clear what it does. It equals the height and/or width from the calling view .

TODO: Add more function descriptions.

jvconstraintedges's Issues

Remove the one-edge-only initializers and add default nil values to the initializer that takes all 4 edges

Safes a few lines of code
