DuctTape
let label = UILabel().ductTape
.numberOfLines(0)
.textColor(.red)
.text("Hello, World!!")
.build()
Above is same as below definition.
let label: UILabel = {
let label = UILabel()
label.numberOfLines = 0
label.textColor = .red
label.text = "Hello, World!!"
return label
}()
Usage
NSObject already has been compatible with DuctTape, so you can access .ductTape
property like below.
let builder: Builder<UIView> = UIView().ductTape
If you access .ductTape
, it returns Builder
that provides setter of properties via KeyPath dynamicMemberLookup.
let view: UIView = UIView().ductTape
.backgroundColor(.red)
.translatesAutoresizingMaskIntoConstraints(false)
.build()
Finally, If you call .build()
, Builder
returns instance that has set property values.
If some objects are not compatible with DuctTape, there are two ways to use DuctTape.
- Use DuctTapeCompatible
class Dog: DuctTapeCompatible {
var name: String
}
let dog = Dog().ductTape
.name("Copernicus")
.build()
- Use Builder directly
class Dog {
var name: String
}
let dog = Builder(Dog())
.name("Copernicus")
.build()
Sample
class ViewController: UIViewController {
let flowLayout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
.ductTape
.minimumLineSpacing(10)
.minimumInteritemSpacing(10)
.itemSize(CGSize(width: 100, height: 100))
.scrollDirection(.vertical)
.build()
lazy var collectionView: UICollectionView = UICollectionView(frame: .zero,
collectionViewLayout: flowLayout)
.ductTape
.dataSource(self)
.delegate(self)
.translatesAutoresizingMaskIntoConstraints(false)
.reinforce {
$0.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell")
}
.build()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(collectionView)
NSLayoutConstraint.activate([
view.topAnchor.constraint(equalTo: collectionView.topAnchor),
view.leadingAnchor.constraint(equalTo: collectionView.leadingAnchor),
view.trailingAnchor.constraint(equalTo: collectionView.trailingAnchor),
view.bottomAnchor.constraint(equalTo: collectionView.bottomAnchor)
])
}
}
