যে কেউ শেভরনের সাথে পিছনে বোতামের স্টাইলটি আয়না করার চেষ্টা করছেন তাদের জন্য:
import UIKit
class NextBarButton: UIBarButtonItem {
convenience init(target: Any, selector: Selector) {
// Create UIButton
let button = UIButton(frame: .zero)
// Set Title
button.setTitle("Next", for: .normal)
button.setTitleColor(.systemBlue, for: .normal)
button.titleLabel?.font = UIFont.systemFont(ofSize: 17)
// Configure Symbol
let config = UIImage.SymbolConfiguration(pointSize: 19.0, weight: .semibold, scale: .large)
let image = UIImage(systemName: "chevron.right", withConfiguration: config)
button.setImage(image, for: .normal)
// Add Target
button.addTarget(target, action: selector, for: .touchUpInside)
// Put the Image on the right hand side of the button
// Credit to liau-jian-jie for this part
button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
// Customise spacing to match system Back button
button.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: -18.0, bottom: 0.0, right: 0.0)
button.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -12.0, bottom: 0.0, right: 0.0)
self.init(customView: button)
}
}
বাস্তবায়ন:
override func viewDidLoad() {
super.viewDidLoad()
let nextButton = NextBarButton(target: self, selector: #selector(nextTapped))
navigationItem.rightBarButtonItem = nextButton
}
@objc func nextTapped() {
// your code
}
