@IBAction func redButtonAction(_ sender: Any) {
PickedColorEvent(color: UIColor.red, name: "RED").fire()
}
@IBAction func greenButtonAction(_ sender: Any) {
PickedColorEvent(color: UIColor.green, name: "GREEN").fire()
}
@IBAction func blueButtonAction(_ sender: Any) {
PickedColorEvent(color: UIColor.blue, name: "BLUE").fire()
}
@IBAction func resetButtonAction(_ sender: Any) {

}
}Example of how to listen for notifications
class ChildViewController: UIViewController {
@IBOutlet weak var colorName: UILabel!
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
flow_start()
}
override func viewDidDisappear(_ animated: Bool) {
flow_stop()
super.viewDidDisappear(animated)
}
}
extension ChildViewController: FlowDispatcher {
func flow_dispatch(_ event: FlowEvent) {
if let e = event as? PickedColorEvent {
view.backgroundColor = e.color
colorName.text = e.name
}
if event is ResetEvent {
view.backgroundColor = nil
colorName.text = ""
}
}
}Support
You are welcome to use SSEventFlow free of charge.
If you are using and enjoying my work, maybe you could donate me a beer (or if you don’t drink – a coffee and bagel will do just fine, a good kind of bagel though, you know… with wonderful stuff inside to make it glorious).
Please donate via PayPal and just like they say on TV – give generously! It motivates me to keep working on this.
