当我按下应用程序中的按钮时，如何打开Goog​​le地图？ [英] How would I be able to open google maps when I press a button in my app?

问题描述

我有这个应用程序，当用户在我的应用程序中按下按钮时，我想使用谷歌地图或苹果地图打开。我将如何能够做到这一点？有没有像打开应用程序的地图的链接，还是其他东西？如果你能指出我正确的方向，那将是非常有用的。谢谢！

  override func touchesEnded（touches：Set< UITouch> ;, withEvent event：UIEvent？ ）{
 
触摸（触摸）{
 let location = touch.locationInNode（self）
 let node = self.nodeAtPoint（location）
 
 if node.name ==openMaps{
 
 //打开谷歌地图或苹果地图的代码.... 
 
} 
  
 <$ p $  
 
 
 $ b $如果使用UIApplication.sharedApplication（）。canOpenURL（NSURL（）（）;如果node.name ==openMaps{
 let customURL =comgooglemaps：//
 
，字符串：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：UIAlertAc tionStyle.Default，handler：nil）
 alert.addAction（ok）
 self.presentViewController（alert，animated：true，completion：nil）
} 
} 
  

您可以在Google地图网址方案此处

编辑：您必须为您的钥匙添加钥匙 info.plist 为此工作。

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

编辑：每更新 Google地图文档在plist上添加了googlechromes。

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 maps that opens the app or is it something else? If you can point me in the right direction it would be really helpful. Thanks! I have the button set up below like this:

override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {

    for touch in (touches ) {
    let location = touch.locationInNode(self)
    let node = self.nodeAtPoint(location)

    if node.name == "openMaps" {

     //code to open google maps or apple maps....

    }

解决方案

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.
