Swift Create Custom Button Programmatically With Code Examples
Through the usage of the programming language, we are going to work collectively to unravel the Swift Create Custom Button Programmatically puzzle on this lesson. This is demonstrated within the code that follows.
let button = self.makeButton(title: "Login", titleColor: .blue, font: UIFont.init(identify: "Arial", dimension: 18.0), background: .white, cornerRadius: 3.0, borderWidth: 2, borderColor: .black)
view.addSubview(button)
// Adding Constraints
button.topAnchor.constraint(equalToFixed: 40).isActive = true
button.leftAnchor.constraint(equalTo: view.leftAnchor, fixed: 40).isActive = true
button.properAnchor.constraint(equalTo: view.properAnchor, fixed: -40).isActive = true
button.backsideAnchor.constraint(equalTo: view.backsideAnchor, fixed: -400).isActive = true
button.addTarget(self, motion: #selector(pressed(_ :)), for: .touchUpInside)
// Define commmon technique
func makeButton(title: String? = nil,
titleColor: UIColor = .black,
font: UIFont? = nil,
background: UIColor = .clear,
cornerRadius: CGFloat = 0,
borderWidth: CGFloat = 0,
borderColor: UIColor = .clear) -> UIButton {
let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle(title, for: .regular)
button.backgroundColor = background
button.setTitleColor(titleColor, for: .regular)
button.titleLabel?.font = font
button.layer.cornerRadius = 6.0
button.layer.borderWidth = 2
button.layer.borderColor = UIColor.purple.cgColor
return button
}
// Button Action
@objc func pressed(_ sender: UIButton) {
print("Pressed")
}
The an identical situation Swift Create Custom Button Programmatically might be resolved utilizing a special technique, which is described within the part beneath with code samples.
let button = UIButton(body: CGRect(x: 20, y: 20, width: 200, top: 60))
button.setTitle("Email", for: .regular)
button.backgroundColor = .white
button.setTitleColor(UIColor.black, for: .regular)
button.addTarget(self, motion: #selector(self.buttonTapped), for: .touchUpInside)
myView.addSubview(button)
@objc func buttonTapped(sender : UIButton) {
//Write button motion right here
}
Utilizing a variety of various examples allowed the Swift Create Custom Button Programmatically downside to be resolved efficiently.
