【Swift】mapviewにピンを立てバルーン表示まで行う

Last updated at Posted at 2020-01-25

#mapkitを使う

mapviewでピンを立て、なおかつバルーン表示などもやっていきたいと思ったときのコード
現在地は不使用(緯度と経度で場所を指定)

なお、緯度と経度は下記のgeocodingで場所検索すれば一発!
http://www.geocoding.jp/

mapkit.swift

import MapKit

class ViewController: UIViewController {

    @IBOutlet weak var myMapView: MKMapView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
    //中心となる場所の座標オブジェクト作成
      //フィリピンのセブ・マクタン空港

   let coordinate = CLLocationCoordinate2DMake(10.310656, 123.98022)
        
   //種尺を設定
   let span = MKCoordinateSpanMake(0.2, 0.2)
             
   //範囲オブジェクトを作成
   let region = MKCoordinateRegionMake(coordinate, span)
        
   //MapViewに範囲オブジェクトを設定
   myMapView.setRegion(region, animated: true)
    
   //ピンを生成
   let myPin = MKPointAnnotation()
        
   //ピンの座標設定
   myPin.coordinate = coordinate
        
   //タイトル、サブタイトルを設定
   myPin.title = "セブ・マクタン空港"
   myPin.subtitle = "Jollibeeうまい"
        
   //mapViewにピンを追加
   myMapView.addAnnotation(myPin) 

      }

override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
}

ここまででとりあえずピンが中心地に立ち
タイトル、サブタイトルまで出るようになった

【備考】
Jollibeeはフィリピンのマクドナルドみたいな感じ
