ios - 打开谷歌地图应用程序以从另一个应用程序进行导航

Question

我尝试使用这些代码从我的应用程序打开谷歌地图应用程序

if (UIApplication.sharedApplication().canOpenURL(NSURL(string:"comgooglemaps://")!)) {
        UIApplication.sharedApplication().openURL(NSURL(string:
            "comgooglemaps://?saddr=\(fromLatitude),\(fromLongitude)&daddr=\(toLatitude),\(toLongitude)&directionsmode=driving")!)
    }else{
        showAlert()
    }

我已经在我的 iPhone 中安装了谷歌地图，但这段代码总是会转到其他部分

Launch Services (part of the Core Services framework in macOS) provides support for launching apps and matching document types to apps.

您应该将其包含在您的info.plist 文件中

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

如果没有安装谷歌地图，您可以在浏览器中打开。

// if GoogleMap installed
if (UIApplication.shared.canOpenURL(URL(string:"comgooglemaps://")!)) {
    UIApplication.shared.openURL(NSURL(string:
        "comgooglemaps://?saddr=\(fromLatitude),\(fromLongitude)&daddr=\(toLatitude),\(toLongitude)&directionsmode=driving")! as URL)

} else {
    // if GoogleMap App is not installed
    UIApplication.shared.openURL(NSURL(string:
                "https://www.google.co.in/maps/dir/?saddr=\(fromLatitude),\(fromLongitude)&daddr=\(toLatitude),\(toLongitude)&directionsmode=driving")! as URL)
}
