Example - Implementing delegate in Swift

// 1.Make a protocol
// จะเขียนแยกใส่ไฟล์(.swift)หรือเขียนใน Class ที่จะเรียกใช้ delegate ก็ได้
protocol messageSenderDelegate{
    func receivedMessage(message:String)
}

// 2.Declare delegate you want to call
// สร้างตัวแปรสำหรับเก็บ class ที่เป็น delegate มารอไว้

MKCoordinateRegion theRegion = mapView.region

//Zoom out
theRegion.span.longitudeDelta *= 2.0
theRegion.span.latitudeDelta *= 2.0

mapView.setRegion(theRegion, animated: true)

// Struct
public struct MKCoordinateRegion {
    public var center: CLLocationCoordinate2D
    public var span: MKCoordinateSpan
    public init()
    public init(center: CLLocationCoordinate2D, span: MKCoordinateSpan)
}

// Setting region
MKCoordinateRegionMake(centerCoordinate: CLLocationCoordinate2D, span: MKCoordinateSpan)

kolathee

//Get previous map center
mapCenter = myMapView.centerCoordinate

//Set new location
mapCenter = mapView.convert(CGPoint.init(x: 1, y: mapView.frame.size.height/2.0), toCoordinateFrom: mapView)

//Set new center
mapView.setCenter(mapCenter, animated: true)

//====== MapKit ======================================

//  1.Import MapKit
import Mapkit

//  2.Imprement MKMapViewDelegate, CLLocationManagerDelegate
class ViewController: UIViewController, MKMapViewDelegate {
    
    @IBOutlet weak var mapView: MKMapView!

//1.Inheritance UIPickerViewDelegate, UIPickerViewDataSource
class RadioVC: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
    @IBOutlet weak var pickerView: UIPickerView!
	
    //2.Create data source for picker view
    let pickerData = ["Tree","Cup","Goal","Blast"]
  
    override func viewDidLoad() {
        super.viewDidLoad()
    //3.Set delegate
