如何在swift中添加位置圖標？

Question

我該如何將這些東西添加到我的項目中。它們是否集成在MKMapView？

我沒有找到關於他們的互聯網什麼。

1. 上創建MKMapView的頂部的兩個按鈕添加則它們的約束在viewDidLayourSubviews功能編寫此代碼舍入所希望的角部和陰影和圖像添加到按鈕。從身份檢查員中選擇他們的淺灰色背景顏色。

   override func viewDidLayoutSubviews() { 
   
   let infoButtonShape = CAShapeLayer() 
   infoButtonShape.bounds = infoButton.frame 
   infoButtonShape.position = infoButton.center 
   
   let locationButtonShape = CAShapeLayer() 
   locationButtonShape.bounds = locationButton.frame 
   locationButtonShape.position = locationButton.center 
   
   
   infoButton.clipsToBounds = true 
   infoButton.layer.masksToBounds = false 
   infoButton.layer.shadowColor = UIColor.white.cgColor 
   infoButton.layer.shadowRadius = 2 
   infoButton.layer.shadowOpacity = 0.5 
   infoButton.layer.shadowOffset = CGSize(width: 2, height: -2) 
   infoButton.layer.shadowPath = UIBezierPath(rect: infoButton.bounds).cgPath 
   
   
   
   locationButton.clipsToBounds = true 
   locationButton.layer.masksToBounds = false 
   locationButton.layer.shadowColor = UIColor.white.cgColor 
   locationButton.layer.shadowRadius = 2 
   locationButton.layer.shadowOpacity = 0.5 
   locationButton.layer.shadowOffset = CGSize(width: -2, height: 2) 
   locationButton.layer.shadowPath = UIBezierPath(rect: locationButton.bounds).cgPath 
   
   infoButton.layer.shouldRasterize = true 
   locationButton.layer.shouldRasterize = true 
   
   locationButtonShape.path = UIBezierPath(roundedRect: locationButton.bounds, byRoundingCorners: [UIRectCorner.bottomLeft , UIRectCorner.bottomRight], cornerRadii: CGSize(width:10.0, height:10.0)).cgPath 
   
   infoButtonShape.path = UIBezierPath(roundedRect: infoButton.bounds, byRoundingCorners: [UIRectCorner.topRight , UIRectCorner.topLeft], cornerRadii: CGSize(width:10.0, height:10.0)).cgPath 
   
   infoButton.layer.mask = infoButtonShape 
   locationButton.layer.mask = locationButtonShape 
   
   infoButton.contentMode = .scaleAspectFit 
   locationButton.contentMode = .scaleAspectFit 
   
   
   infoButton.setImage(#imageLiteral(resourceName: "information-icon-3"), for: .normal) 
   locationButton.setImage(#imageLiteral(resourceName: "LocationArrow-512"), for: .normal) 
   
   
   } 
   

2. 然後添加按鈕的IBAction更新位置

   let manager = CLLocationManager() 
   
   func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
   
   //Use location.last add to map then stop updating location 
   manager.stopUpdatingLocation() 
   
   } 
   
   @IBAction func updateLocationAction(_ sender: UIButton) { 
   
   manager.startUpdatingLocation() 
   } 
   

3. 對於兩個其它UIViews只是創建一個UILabel用於溫度以及用於雲圖標一個的UIImageView。對於UILabel和UIImageView的背景顏色及其圓角半徑，您可以做類似於我爲按鈕所做的操作，但是這次爲UIImageView和UILabel的左角選擇了正確的角點。

這裏是輸出：當然，您可以使用更好的大小的圖標圖像爲您的按鈕。
