How to show location in Apple Maps and Google Maps app in iOS

Issue #309

Apple Maps

let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: nil)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = shop.name
mapItem.openInMaps(launchOptions: [:])

Google Maps

• https://developers.google.com/maps/documentation/urls/ios-urlscheme
• Use q to show pin

Since iOS 9, we need to declare LSApplicationQueriesSchemes

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>comgooglemaps</string>
</array>

var string = "comgooglemaps://"
string += "?q=Food"
string += "&center=\(coordinate.latitude),\(coordinate.longitude)"
string += "&zoom=15"
let googleUrl = URL(string: string)!

if UIApplication.shared.canOpenURL(URL(string: "comgooglemaps://")!) {
    UIApplication.shared.open(googleUrl)
}
