ApplyStyleKit
ApplyStyleKit is a library that applies styles to UIKit using Swifty Method Chain.
Normally, when applying styles to UIView etc.,it is necessary to write propertyName and equal operator many times.
With ApplyStyleKit, you can comfortably apply style to your code.
Like this:
sampleLabel.applyStyle
.backgroundColor(.yellow)
.text("sample label")
.textAlignment(.center)
.textColor(.green)
.font(.boldSystemFont(ofSize: 30.0))
.numberOfLines(0)
Installation
Requirements
- iOS 9.0 or later
- Swift 4.2
- Xcode 10
Carthage
github "shindyu/ApplyStyleKit"
CocoaPods
target '<Your Target Name>' do
pod 'ApplyStyleKit'
end
Usage
import ApplyStyleKit
class ViewController: UIViewController {
let sampleView = UIView()
let sampleLabel = CustomLabel()
override func viewDidLoad() {
super.viewDidLoad()
// Apply style
sampleView.applyStyle
.backgroundColor(.red)
.alpha(0.5)
// When applying to layer
sampleView.layer.applyStyle
.cornerRadius(10)
.borderColor(.gray)
.borderWidth(2)
// Of course, you can apply it if you inherit UIView etc.
sampleLabel.applyStyle
.text("Of course, you can apply it if you inherit UIView etc.")
.textAlignment(.center)
.textColor(.green)
.font(.boldSystemFont(ofSize: 30.0))
.numberOfLines(0)
}
}
Advanced
You can also create your own applyStyleMethod.
To be able to define the extension, the access modifier of base which is a property of StyleObject is public.
example:
extension StyleObject where Base: UIView {
@discardableResult func specialStyle() -> StyleObject {
base.backgroundColor = .red
base.layer.cornerRadius = 10
return self
}
}

Basic policy
ApplyStyleKit intends to target methods with no return value and properties with setter. Due to the nature of ApplyStyleKit, I think that returning types other than StyleObject should be avoided.
