How would I be able to open google maps when I press a button in my app?

Question

I have this app and I want to use google maps or apple maps to open when the user presses a button in my app. How would I be able to do this? Is there like a link to the map

Answer 1

Use this:

if node.name == "openMaps" {
    let customURL = "comgooglemaps://"

    if UIApplication.sharedApplication().canOpenURL(NSURL(string: customURL)) {
        UIApplication.sharedApplication().openURL(NSURL(string: customURL))
    }
    else {
        var alert = UIAlertController(title: "Error", message: "Google maps not installed", preferredStyle: UIAlertControllerStyle.Alert)
        var ok = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)
        alert.addAction(ok)
        self.presentViewController(alert, animated:true, completion: nil)
    }
}

You can find more info about the google maps URL scheme here

Edit: You must add a key to your info.plist for this to work.

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

Edit: Per updated Google Maps docs added "googlechromes" to plist above also.

At button click (in action) call function "directions()" with following code :

func directions() {
    // if GoogleMap installed
    if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {
        UIApplication.shared.openURL(NSURL(string:
            "comgooglemaps://?saddr=&daddr=\(Float(event.addressLat)!),\(Float(event.addressLong)!)&directionsmode=driving")! as URL)

    } else {
        // if GoogleMap App is not installed
        UIApplication.shared.openURL(NSURL(string:
            "https://maps.google.com/?q=@\(Float(event.addressLat)!),\(Float(event.addressLong)!)")! as URL)
    }
}

Edit your info.plist for LSApplicationQueriesSchemes :

Hope will help!
