【问题描述】：
我在互联网上阅读，但找不到合法的答案。当用户单击按钮以显示路线时，我需要打开 Google 地图。起点和终点必须自动填写。
如何在 Swift 中实现这一点？
如果有人有解决方案，请提供示例代码。起点始终是用户的当前位置。

【问题描述】：
好的，我自己找到了答案。
如果您想显示从用户当前位置出发的路线，请将字段 saddr 留空，并在字段 daddr 中输入目的地坐标。
我就是这样做的
if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"comgooglemaps://")!)) {
UIApplication.sharedApplication().openURL(NSURL(string:
"comgooglemaps://?saddr=&daddr=\(place.latitude),\(place.longitude)&directionsmode=driving")!)
} else {
NSLog("Can't use comgooglemaps://");
}
}
如有任何进一步的疑问，您可以参考此链接Google Map URL Scheme

-
抱歉，您的 place 变量在 place.latitude 中是什么？我有这个网址“maps.google.com/…”，但我不知道抽象 2.721966 和 101.94508010000004
-
您是如何添加按钮的？我已经设法显示地图并添加了标记，但是当我单击标记时，按钮没有显示，请问您能提供您的代码吗？
-
您知道如何在路线中添加航点（多个位置）吗？
-
我使用了你的代码。但我在我的设备谷歌地图中遇到了问题，没有安装，但在其他情况下仍然没有触发。
-
显示当前位置和目的地，直到我按下谷歌地图上的汽车或自行车图标后才会显示路线。有什么帮助吗？
Swift 5 - 代码
func openGoogleMap() {
guard let lat = booking?.booking?.pickup_lat, let latDouble = Double(lat) else {Toast.show(message: StringMessages.CurrentLocNotRight);return }

这里是 Swift 3 更新
首先，您需要在 info.plist 中将两个项目添加到LSApplicationQueriesSchemes。
然后你就可以使用这个功能在谷歌地图上加载地址了。
let primaryContactFullAddress = "No 28/A, Kadalana, Moratuwa, Sri Lanka"
@IBAction func showLocaionOnMaps(_ sender: Any) {
let testURL: NSURL = NSURL(string: "comgooglemaps-x-callback://")!
if UIApplication.shared.canOpenURL(testURL as URL) {
if let address = primaryContactFullAddress.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) {
let directionsRequest: String = "comgooglemaps-x-callback://" + "?daddr=\(address)" + "&x-success=sourceapp://?resume=true&x-source=AirApp"
let directionsURL: NSURL = NSURL(string: directionsRequest)!
let application:UIApplication = UIApplication.shared
if (application.canOpenURL(directionsURL as URL)) {
application.open(directionsURL as URL, options: [:], completionHandler: nil)
}
}
} else {
NSLog("Can't use comgooglemaps-x-callback:// on this device.")
}
}
【讨论】：
-
谢谢！这正是我想要的，拥有完整的目的地地址。
Swift 4 工作代码
if let url = URL(string: "comgooglemaps://?saddr=&daddr=\(location.coordinate.latitude),\(location.coordinate.longitude)&directionsmode=driving") {
UIApplication.shared.open(url, options: [:])
}
此代码对我有用。而且我没有插入
* LSApplicationQueriesSchemes
如果你使用模拟器是看不到结果的。不要忘记在电话上处理您的项目。
【讨论】：
-
它也会播放语音指令吗？
-
是的。如果您的设备有谷歌地图应用程序，您可以播放语音指令。这可以使用浏览器导航谷歌地图。当页面打开时，谷歌会自动显示警报，例如“open google maps app bla bla”
1) 方法：你可以传递唯一的目的地地址当前地址将被谷歌地图应用程序自动获取。
let strLat : String = "23.035007"
let strLong : String = "72.529324"
override func viewDidLoad() {
super.viewDidLoad()
if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {
UIApplication.shared.openURL(URL(string:"comgooglemaps://?saddr=&daddr=\(strLat),\(strLong)&directionsmode=driving")!)
}
else {
print("Can't use comgooglemaps://");
}
}
2) 您可以同时传递起始地址和目标地址
let strLat : String = "23.035007"
let strLong : String = "72.529324"
let strLat1 : String = "23.033331"
let strLong2 : String = "72.524510"
override func viewDidLoad() {
super.viewDidLoad()
if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {
UIApplication.shared.openURL(URL(string:"comgooglemaps://?saddr=\(strLat),\(strLong)&daddr=\(strLat1),\(strLong2)&directionsmode=driving&zoom=14&views=traffic")!)
}
else {
print("Can't use comgooglemaps://");
}
}
【讨论】：
我希望用户可以通过浏览器打开谷歌地图（仅当用户没有谷歌地图应用时才有效） Google 提供了该here 的文档。 从 iOS 9 开始，您必须设置一个方案。这个你会找到here。
对我来说，谷歌解决方案不起作用。也许您更聪明并找到了解决方案（请发布！）。
反正我打了一个简单的网络电话：
let lat = 37.7
let lon = -122.4
if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"https://maps.google.com")!))
{
UIApplication.sharedApplication().openURL(NSURL(string:
"https://maps.google.com/?q=@\(lat),\(lon)")!)
}
这可以用作 sumeshs 答案的一种后备。

您可以为 URL 创建小型构建器，这会将您重定向到 GoogleMaps

public enum NavigationType: String {
case driving
case transit
case walking

public class func prepareURIFor(latitude lat: Double,
longitude long: Double,
fromLatitude fromLat: Double? = nil,
fromLongitude fromLong: Double? = nil,
navigation navigateBy: NavigationType) -> URL? {
if let googleMapsRedirect = URL(string: "comgooglemaps://"),
UIApplication.shared.canOpenURL(googleMapsRedirect) {

let fromLong = fromLong {

嗨 gbk，它在应用程序的源和目标上显示纬度和经度。这不是很好的用户体验。我们如何显示那些经纬度的真实地址？
首先，谢谢你们的回答。但是当我工作时，我没有找到适合我的工作答案。结果我用两种情况编写了工作代码：当用户有谷歌地图应用程序时，如果没有。 这是我的代码版本。 Xcode 10，斯威夫特 4.2。希望它会有所帮助。
第 1 步：找到您的 info.plist 并打开为 -> 源代码
第 2 步：在<dict> 和</dict> 之间添加这些行
第 3 步：在您的操作中添加此代码。不要忘记设置您的纬度和经度。
let latitude = 44.987781
let longitude = 88.987781
let appDomen: String = "comgooglemaps://"
let browserDomen: String = "https://www.google.co.in/maps/dir/"
let directionBody: String = "?saddr=&daddr=\(latitude),\(longitude)&directionsmode=driving"
// Make route with google maps application
if let appUrl = URL(string: appDomen), UIApplication.shared.canOpenURL(appUrl) {
guard let appFullPathUrl = URL(string: appDomen + directionBody) else { return }

这是在苹果和谷歌地图之间选择导航应用程序的简单解决方案（如果已安装，否则系统将导航到默认的苹果地图）。
在您的项目中添加这个 OpenMaps 类。
class OpenMaps {
// Presenting Action Sheet with Map Options Like Google And Apple Maps.
/// - Parameter coordinate: coordinate of destination
static func presentActionSheetwithMapOption(coordinate: CLLocationCoordinate2D) {
let latitude = coordinate.latitude
let longitude = coordinate.longitude
// Google MAP URL
let googleURL = "comgooglemaps://?daddr=\(latitude),\(longitude)&directionsmode=driving"
let googleItem = ("Google Maps", URL(string:googleURL)!)
// Apple MAP URL
let appleURL = "maps://?daddr=\(latitude),\(longitude)"
var installedNavigationApps = [("Apple Maps", URL(string:appleURL)!)]
if UIApplication.shared.canOpenURL(googleItem.1) {
installedNavigationApps.append(googleItem)
}
if installedNavigationApps.count == 1 {
if let app = installedNavigationApps.first {
self.openMap(app: app)
}
return
}
// If there are google map install in the device then System will ask choose map application between apple and google map.
let alert = UIAlertController(title: nil,
message: "Choose application",
preferredStyle: .actionSheet)
for app in installedNavigationApps {
let button = UIAlertAction(title: app.0,
style: .default, handler: { _ in
self.openMap(app: app)

alert.addAction(cancel)
