AlertViewController is a customizable replacement for native UIAlertController.
Sometimes we need to set NSAttributedString into native alert, but public API doesn't allow it. As a workaroud we could use private API, but in general we should avoid using it.
AlertViewController looks exactly like native UIAlertController, but very configurable.
- Default initialization with title, message as
String.
let cancelAction = Alert.Action(title: "Cancel", style: .primary) let confirmAction = Alert.Action(title: "Confirm", style: .default) let viewModel = Alert( title: "Your Title", titleFont: ... // your custom title font message: "Your Message", messageFont: ... // your custom message font actions: [cancelAction, confirmAction] ) let alert = AlertViewController(viewModel: viewModel) present(alert, animated: true)- Default initialization with title, message as
NSAttributedString
let cancelAction = Alert.Action(title: "Cancel", style: .primary) let confirmAction = Alert.Action(title: "Confirm", style: .default) let viewModel = Alert( title: ... // your title (NSAttributedString) message: ... // your message (NSAttributedString) actions: [cancelAction, confirmAction] ) let alert = AlertViewController(viewModel: viewModel) present(alert, animated: true)- Initialization with title, message and custom
UIViewobject as content view to implement complex layout.
let cancelAction = Alert.Action(title: "Cancel", style: .primary) let confirmAction = Alert.Action(title: "Confirm", style: .default) let customView = CustomView() customView.translatesAutoresizingMaskIntoConstraints = false customView.imageView.backgroundColor = .orange customView.titleLabel.text = "Some text" customView.subtitleLabel.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua." let viewModel = Alert( title: "Your Title", message: nil, contentView: customView, actions: [cancelAction, confirmAction] ) let alert = AlertViewController(viewModel: viewModel) present(alert, animated: true)See Alert.swift for more details.
When you need to present few alerts in a row you should set shouldDismissAutomatically flag to false and add action AFTER view controller initialization to be able to capture alert instance in action handler's closure.
let viewModel = Alert( title: "Your Title", message: "Your Message" ) let alert = AlertViewController(viewModel: viewModel) alert.shouldDismissAutomatically = false let cancelAction = Alert.Action(title: "Cancel", style: .primary) { [weak alert] _ in alert?.dismiss(animated: true) { // present something else } } alert.addAction(cancelAction) let confirmAction = Alert.Action(title: "Confirm", style: .default) { [weak alert] _ in alert?.dismiss(animated: true) { // present something else } } alert.addAction(confirmAction) present(alert, animated: true)Anton Poltoratskyi
