Apple Mapsを開くためのボタンを追加して道順を取得する

Question

アップルMapsアプリを開くボタンを追加しようとしていて、その場所へのルートが表示されます。ヘルプは非常に高く評価されるだろう！

import UIKit

      let pinImage = UIImage(named: "pawPrint.png") 
      let size = CGSize(width: 30, height: 30)

      annotationView.image = resizedImage     
     } 

     return annotationView 
    }  

}

それはあなたはアップルの地図アプリを開き、任意のコードを追加していないあなたのため

func openMap() { 

    let lat1 : NSString = self.placeLat 
    let lng1 : NSString = self.placeLng 

    let latitute:CLLocationDegrees = lat1.doubleValue 
    let longitute:CLLocationDegrees = lng1.doubleValue 

    let regionDistance:CLLocationDistance = 10000 
    let coordinates = CLLocationCoordinate2DMake(latitute, longitute) 
    let regionSpan = MKCoordinateRegionMakeWithDistance(coordinates, regionDistance, regionDistance) 
    let options = [ 
     MKLaunchOptionsMapCenterKey: NSValue(MKCoordinate: regionSpan.center), 
     MKLaunchOptionsMapSpanKey: NSValue(MKCoordinateSpan: regionSpan.span) 
    ] 
    let placemark = MKPlacemark(coordinate: coordinates, addressDictionary: nil) 
    let mapItem = MKMapItem(placemark: placemark) 
    mapItem.name = "\(self.placeName)" 
    mapItem.openInMapsWithLaunchOptions(options) 

}
