Use consistent help
On iOS, place help buttons consistently across your app to enhance user experience and ensure that users can easily find assistance when needed. Help buttons should be positioned in a way that aligns with the app's overall layout and navigation patterns, such as in the top-right or bottom-right corners of a screen.
swift
class HelpButton: UIButton {
private func configure() {
let config = UIImage.SymbolConfiguration(pointSize: 20, weight: .regular)
let image = UIImage(systemName: "questionmark.circle", withConfiguration: config)
setImage(image, for: .normal)
accessibilityLabel = "Help"
}
}
class ApptViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let helpButton = HelpButton()
// Set constraints consistently across screens
}
