Usage
Init
Create UIView instances from either storyboard or programmatically.
Don't forget to set view.translatesAutoresizingMaskIntoConstraints = false if you are creating them programmatically.
Wraper
The main function of all kit.
Wraps addConstraint: method of autolayout.
func pin(
inView inView: UIView? = nil,
edge: NSLayoutAttribute,
toEdge: NSLayoutAttribute,
ofView: UIView?,
withInset: CGFloat = 0) {
let view = inView ?? ofView ?? self
view.addConstraint(NSLayoutConstraint(
item: self,
attribute: edge,
relatedBy: .Equal,
toItem: ofView,
attribute: toEdge,
multiplier: 1,
constant: withInset))
}Example
box.fill(toView: view)
blue.pinTop(toView: box, withInset: 10)
blue.fillHorizontal(toView: box, withInset: 10)
blue.pinHeight(90)
red.pinBottom(toView: box, withInset: 10)
red.fillHorizontal(toView: box, withInset: 10)
red.pinHeight(90)
yellow.pinToTop(ofView: red, withOffset: 10)
yellow.pinCenterX(toView: red)
yellow.pinSize(width: 50, height: 50)That would be look like this:
